Is PHP a dying language

It seems like this question gets asked every year, as for some reason the perception surrounding PHP is that it is a language used by hobbyists, or a dying language - a programming language on its way out.

Before we take a look at "is PHP being used less," let's start with some critical points to consider when choosing a programming language to learn/ invest in.

PHP powers ~80% of the web


The first point is how popular PHP is as a program language. Recently in a podcast a debate around PHP was raised, with the question being is it an "enterprise" language. The argument against PHP is that it is not widely adopted by enterprises for enterprise application development - or apps that are traditionally developed in Java or .Net.

The key here is understanding that every tool has its strengths and weaknesses, and there are times where using a compiled language such as Java is a smarter move than using PHP. As always, you want to choose the right tool for the job, and PHP as a programming language excels for web applications. That's why today it powers nearly 80% of the websites on the internet! I want to repeat that number, nearly 80% of websites on the internet!

In the podcast, after the initial argument that PHP was not an enterprise language, I had one question to ask - "can you name one enterprise that doesn't use PHP?" Despite the misconception that PHP is not an enterprise language, nearly every enterprise utilizes PHP in some fashion (many for their website, blog, or internal tools). While PHP may not power the app they offer as a service (although for many companies it does), it powers just as critical of offerings that help drive success for the company.

PHP made Yahoo, Facebook, and Tumblr possible


It's not just personal blogs running on a WordPress install, or small sites running on Drupal (btw, both of these power high traffic, well known web properties), but PHP actually makes development for the web easier and faster. Because it is not a compiled language and is designed to scale, companies are able launch faster, add new features as they go, and grow to enormous scale.

Some of the sites that started with PHP include Yahoo, Facebook, Tumblr, Digg, Mailchimp, and Wikipedia! But it's not just older platforms that started off and have grown to scale with PHP - Etsy, Slack, Baidu, Box, and Canva also got started with PHP! Read why Slack chose PHP

In fact, according to BuiltWith, PHP powers 53.22% of the top 10k websites!

Programming languages don't just disappear


Understanding the prevalence of PHP today, and how often it is used is critical to understanding the longevity of PHP. Despite the radicalized idea, programming languages (and thus programming jobs) do not just disappear overnight. Today you can still find jobs writing code used in mainframes - such as Fortran or Cobol.

As long as companies have applications that use PHP, they'll need someone who knows PHP to maintain the application. And with PHP actively being developed and maintained (PHP 8 having just been released), and PHP powerhouses like WordPress, Drupal, SugarCRM, and others powering websites and apps around the world, it's a safe bet PHP won't be going anywhere anytime soon.

But with the basics out of the way, let's look at how PHP has faired over the years.

PHP usage over the years


While there is no exact measurement that determines how programming languages are ranked, there are several different rankings we can look at to see how a language has evolved over the years, and where it ranks today.

GitHub's most popular programming languages


Every year GitHub releases a report of the most popular languages being used to create repositories on GitHub.com. While this isn't an exact way to quantify a programming language, it does help us understand what languages developers are using and promoting for their applications. It also helps us see how lively the community itself is.

In 2014, PHP was ranked as the 3rd most popular programming language, being beat out only by JavaScript and Java. With the emergence of Typescript, C# moving open source, and increased usage of Python for AI - PHP did drop - and was the 6th most popular programming language on GitHub for 2020.

PHP on GitHub over the years

PHP's ranking on the Tiobe index


Another index for software popularity is the Tiobe index, which bases their ratings off of the number of search engines for programming languages. This index is heavily relied on by companies when making programming and investment decisions, especially in developer marketing.

Like with GitHub, PHP has also seen a decline in the Tiobe index. Ranked 8th last year for all languages, PHP dropped to 9th place, being outranked by the C languages (C, C#, C++), Java, Visual Basic, Python, JavaScript, and Assembly. However, to put the rankings in contrast, PHP is 9th out of the 274 languages Tiobe tracks, and bests SQL, Ruby, Groovy, Go, and Swift.

You can see the latest Tiobe index (updated monthly) at: https://www.tiobe.com/tiobe-index/

PHP's ranking on BuiltWith


The last model we'll look at is BuiltWith. BuiltWith scans website headers to determine what a website is powered by, and like GitHub and Tiobe provides a ranking of programming language popularity and trends.

Builtwith provides an interesting perspective in that we can see an explosion of sites being built with PHP (nearly tripling from 2013 to 2016) before dropping and normalizing in 2017. From 2017 to present, the number of sites using PHP has remained almost constant.

BuiltWith PHP Usage

This suggests (as with what we've seen with GitHub and Tiobe) that other languages have grown in popularity, such as JavaScript and Node.js. This doesn't mean that PHP is no longer being used or relied or, but rather that there is more competition and that there are other viable options whereas PHP stood alone at times in terms of being the goto language for web development.

Indeed, when we look at how PHP ranks amongst all technologies on BuiltWith, PHP receives the following BuiltWith awards:

• The most popular on the Entire Internet in Frameworks category.

• The most popular in the Top 10k sites in Frameworks category.

• The most popular in the Top 100k sites in Frameworks category.

• The most popular in the Top 1 Million sites in Frameworks category.

Conclusion


PHP's popularity has dropped from its height 10 years ago, however it still remains the most popular programming language powering the web. It's important to remember that every tool has pros and cons, and some of the bad rap PHP gets is when compared to languages designed to accomplish tasks or build programs that PHP was never designed to.

It's also important to remember a lot of early criticism for PHP came from it being a procedural programming language and not encompassing Object Oriented Programming capabilities. These capabilities were added in PHP 4 and with PHP 7 & 8 OOP has become a staple of the PHP language.

PHP is a viable, powerful language used by nearly every enterprise and many businesses large and small. In fact it powers over 50% of the top 10,000 websites on the web! With such large usage, popular tools such as WordPress, and an active community, it is safe to assume that PHP will remain a prominent language for years to come.

To bridge the gap between web-based and cloud-based applications, businesses often rely on skilled DevOps developers. These professionals play a crucial role in ensuring seamless integration, efficient customization, and robust back-end infrastructure for applications. The expertise of DevOps developers is indispensable for optimizing development workflows and enhancing collaboration between development and operations teams in the dynamic landscape of app development services.

In the realm of cloud computing, web based application in cloud computing play a pivotal role. Technically, web apps, as the name suggests, are applications hosted on remote servers & accessible through web browsers. On the other hand, cloud-based apps are web applications that come with advanced functionalities & elaborate compatibility.


In the realm of contemporary software development, the demand for innovative solutions is evident in the competition between web and cloud-based applications. These two platforms share similarities but diverge significantly in crucial aspects. This article will delve into the distinctions between web-based and cloud-based applications, exploring facets such as back-end infrastructure, scalability, and technical perspectives, shedding light on the nuances that developers navigate in this dynamic landscape, including the pivotal role of technologies like chatbot development.
What Is a Web Application?

A web-based app is an application designed and developed for the web browser. Unlike cloud based application development, the web app completely depends on the web server for functionality & processing. This application program is mainly stored on the remote server & delivered through a web browser interface over the internet. According to web application development company, web apps have client-server architecture & their codes are divided into 2 major components – server-side architecture & client-side architecture.

Server-side architecture: The server-side architecture or script usually deals with data processing. The web server can process a client request & send a response back. This web app architecture defines a simultaneous interaction between database instances, components, user interfaces, middleware systems, and servers.

Client-side architecture: The client-side architecture mainly deals with interface functionalities such as drop-down boxes and buttons. When a user clicks on the link, the browser will start loading the client-side script & rendering a text and graphic element for interaction.
Types of Web Apps
Nowadays, many businesses are already adopting various kinds of web-based applications because of their several advantages, features, and functionalities. 8 most popular types of web apps include:
    . Static Web Apps
Static web applications, constructed using HTML, CSS, and JavaScript, lack the flexibility of dynamic counterparts. These web based services provide content directly to users without requiring server-side modifications, resulting in simplicity and straightforward development. Key benefits of these apps include:
Very fast load time
Highly secure
Less complex to build
    . Dynamic Web Apps
This is a complex type that provides real-time data based on the server response and the user’s request. Dynamic web apps can be developed either as a conventional website with several pages and levels of navigation or as a single-page web application. They use several server-side and client-side languages to create web pages such as HTML, CSS, JavaScript, Python, PHP, Ruby, etc. Key benefits of dynamic web apps include:
Wider audience reach
Scalable in comparison to static web apps
Very flexible in terms of a new content update
    . Single Page Apps
A single page web app entirely runs on the browser & never requires browser reloading. This is actually a dynamic web app that manages all data on a single HTML page. This type of web app is faster than traditional websites as its logic is implemented in the browser directly than a server. Gmail, Netflix, Pinterest & Paypal are the best examples of single page applications. Key benefits include:
Enhanced user experience
Minimized server load
Improved app performance
    . Multiple-Page Apps
Multiple page apps are designed multiple pages separately and combined to form a website. They have different pages with static information like texts & images. Web based app development companies recommend using multiple-page apps as they offer excellent control over search engine optimization techniques. Major benefits of Multiple page apps include:
Ideal for SEO
Quick browser back or forward navigation
Simple to develop
    . Animated Web Apps
This is a type of web application that effectively supports synchronization & animation on the web platform. These applications are widely used by freelancers and creative companies to present their creativity better. Technically, JavaScript, HTML5, FLASH, and CSS are used to create animated web applications. Key benefits of AWAs include
Improved User Engagement
Enhanced Navigation
Excellent Branding
    . Web Apps with CMS
In this web application, content is updated constantly. It helps to manage, modify and create digital content with ease. WordPress is one of the best examples of CMS web applications. A variety of languages are used to create content management systems such as C#, PHP, Java, and Python. Key advantages of CMS web apps include:
Quick content creation & management
Efficient & quick updates
A vast range of features
    . E-commerce Web Apps

What is a Cloud Based App?
These apps are online software programs with elements accessible via a local server and executed on the cloud environment. As internet-based software, cloud applications are stored in the remote data center & handled by cloud-service providers. These apps are used for file sharing & storage, order entry, word processing, inventory management, financial accounting, customer relationship management, data collection, etc.

According to the report, the global market size of cloud apps is projected to reach approx 168.6 billion USD by 2025. Cloud apps usually support several user requirements through customization and provide several services to meet storage, backup & security needs. Some major characteristics of cloud apps include:
Agile application
Microservices-oriented
API-backed
Continuously integrated & delivered
DevOps-enabled
Analytics-infused
User experience-centric
Types of Cloud-based Applications
Cloud apps are divided into three major cloud computing models – SaaS, PaaS, and IaaS. Each model also shows several parts of cloud computing stacks. Take a closer look at these types:
    . SaaS or Software as a Service
SaaS is one of the best cloud apps that enable users to easily access full-functioning software applications over the internet. These cloud applications are primarily designed for freelance services, large enterprises & SMBs. Some of the best examples of SaaS applications are HubSpot CRM, Wrike, MS Office 365, Sisense, Wix, etc.
    . PaaS or Platform as a Service
PaaS provides users with the infrastructure, computing platforms, and solutions to build their own applications. Platform as a Service is ideal for businesses that mainly engage in collaboration, testing, and development of cloud solutions. PaaS applications have a deployment environment including run-time system libraries, operating systems, and graphic UI. Some of the best examples of PaaS apps are Google App Engine, Microsoft Azure, Rackspace Cloud Sites, etc.
    . IaaS or Infrastructure as a Service
IaaS consists of basic building blocks that offer access to networking functionalities, features & data storage space. It enables users to outsource IT infrastructures like servers, processing, virtual machines, storage, networking & other resources. IaaS applications also offer a good level of management control and flexibility over IT resources. Some of the best examples of IaaS apps are Amazon WorkSpaces, IBM Cloud, Google Cloud, etc.
Benefits of Cloud Apps
Web based application in cloud computing boost productivity, accessibility, security, and data safety. They help businesses make the process of collaboration more effective and easier. Key benefits of cloud applications include:
Minimal service provider interaction & management effort
Provides large computing capabilities, online & offline
Provides access to information from any device or place
Offers fast access to important applications through cloud servers
The performance of the availability of cloud apps enhances profitability & streamlines workflows
Serves multiple consumers with virtual and physical needs
Provides high transparency to resource providers & consumers
Offers improved collaboration options

Create Alarm and Monitoring on Custom Memory and Disk Metrics for Amazon EC2

Today I am going write a blog on how to Monitor Memory and Disk custom metrics and creating alarm in Ubuntu.

To do this, we can use Amazon CloudWatch, which provides a flexible, scalable and reliable solution for monitoring our server.

Amazon Cloud Watch will allow us to collect the custom metrics from our applications that we will monitor to troubleshoot any issues, spot trends, and configure operational performance. CloudWatch functions display alarms, graphs, custom metrics data and including statistics.

Installing the Scripts


Before we start installing the scripts for monitoring, we should install all the dependent packages need to perform on Ubuntu.

First login to your AWS server, and from our terminal, install below packages

sudo apt-get update
sudo apt-get install unzip
sudo apt-get install libwww-perl libdatetime-perl


Now Install the Monitoring Scripts


Following are the steps to download and then unzip we need to configure the Cloud Watch Monitoring scripts on our server:
1. In the terminal, we need to change our directory and where we want to add our monitoring scripts.
2. Now run the below command and download the source:

curl https://aws-cloudwatch.s3.amazonaws.com/downloads/CloudWatchMonitoringScripts-1.2.2.zip -O

3. Now uncompress the currently downloaded sources using the following commands

unzip CloudWatchMonitoringScripts-1.2.2.zip && \

rm CloudWatchMonitoringScripts-1.2.2.zip && \

cd aws-scripts-mon


The directory will contain Perl scripts, because of the execution of these scripts only report memory run and disk space utilization metrics will run in our Ubuntu server.
Currently, our folder will contain the following files:
mon-get-instance-stats.pl - This Perl file is used to displaying the current utilization statistics reports for our AWS instance on which these file scripts will be executed.
mon-put-instance-data.pl - This Perl script file will be used for collecting the system metrics on our ubuntu server and which will send them to the Amazon Cloud Watch.
awscreds.template - This Perl script file will contain an example for AWS credentials keys and secret access key named with access key ID.
CloudWatchClient.pm - This Perl script file module will be used to simplify by calling Amazon Cloud Watch from using other scripts.
LICENSE.txt – This file contains the license details for Apache 2.0.
NOTICE.txt – This file contains will gives us information about Copyright notice.
4. For performing the Cloud Watch operations, we need to confirm that whether our scripts have corresponding permissions for the actions:

If we are associated with an IAM role with our EC2 Ubuntu instance, we need to verify that which will grant the permissions to perform the below-listed operations:

cloudwatch:GetMetricStatistics

cloudwatch:PutMetricData

ec2:DescribeTags

cloudwatch:ListMetrics


Now we need to copy the ‘awscreds.template’ file into ‘awscreds.conf’ by using the command below and which will update the file with details of the AWS credentials.

cp awscreds.template awscreds.conf

AWSAccessKeyId = my_access_key_id

AWSSecretKey = my_secret_access_key


Now we completed the configuration.

mon-put-instance-data.pl


This Perl script file will collect memory, disk space utilization data and swap the current system details and then it makes handling a remote call to Amazon Cloud Watch to reports details to the collected cloud watch data as a custom metrics.

We can perform a simple test run, by running the below without sending data to Amazon CloudWatch

./mon-put-instance-data.pl --mem-util --verify --verbose


Now we are going to set a cron for scheduling our metrics and we will send them to Amazon CloudWatch
1. Now we need to edit the crontab by using below command:

 crontab -e

2. Now we will update the file using the following query which will disk space utilization and report memory for particular paths to Amazon CloudWatch in every five minutes:

*/5 * * * * ~/STORAGE/cloudwatch/aws-scripts-mon/mon-put-instance-data.pl --mem-util --mem-avail --mem-used --disk-space-util --disk-space-avail --disk-space-used --disk-path=/ --disk-path=/STORAGE --from-cron


If there is an error, the scripts will write an error message in our system log.

Use of Options

--mem-used
The above command will collect the information about used memory and which will send the details of the reports in MBs into the MemoryUsed metrics. This will give us information about the metric counts memory allocated by applications and the OS as used.
--mem-util
The above command will collect the information about memory utilization in percentages and which will send the details of the Memory Utilization metrics and it will count the usage of the memory applications and the OS.
--disk-space-util
The above command will collect the information to collect the current utilized disk space and which will send the reports in percentages to the DiskSpaceUtilization for the metric and for the selected disks.
--mem-avail
The above command will collect the information about the available memory and which will send the reports in MBs to the MemoryAvailable metrics details. This is the metric counts memory allocated by the applications and the OS as used.
--disk-path=PATH
The above command will collect the information and will point out the which disk path to report disk space.
--disk-space-avail
The above command will collect the information about the available disk space and which will send the reports in GBs to the DiskSpaceAvailable metric for the selected disks.
--disk-space-used
The above command will collect the information about the disk space used and which will send the reports in GBs to the DiskSpaceUsed metric for the selected disks.

The PATH can specify to point or any of the files can be located on which are mounted point for the filesystem which needs to be reported.

If we want to points to the multiple disks, then specify both of the disks like below:

--disk-path=/ --disk-path=/home


Setting an Alarm for Custom Metrics


Before we are going to running our Perl Scripts, then we need to create an alarm that will be listed in our default metrics except for the custom metrics. You can see some default metrics are listed in below image:



Once we completed setting the cron, then the custom metrics will be located in Linux System Metrics.

Now we are going to creating the alarm for our custom metrics
1. We need to open the cloudwatch console panel at https://console.aws.amazon.com/cloudwatch/home
2. Now navigate to the navigation panel, we need to click on Alarm and we can Create Alarm.
3. This will open a popup which with the list of the CloudWatch metrics by category.
4. Now click on the Linux System Metrics . This will be listed out with custom metrics you can see in the below pictures






5. Now we need to select metric details and we need to click on the NEXT button. Now we need to navigate to Define Alarm step.



6. Now we need to define an Alarm with required fields

Now we need to enter the Alarm name for identifying them. Then we need to give a description of our alarm.

Next, we need to give the condition with the maximum limit of bytes count or percentage when it notifies the alarm. If the condition satisfies, then the alarm will start trigger.

We need to provide a piece of additional information about for our alarm.

We need to define what are the actions to be taken when our alarm changes it state.

We need to select or create a new topic with emails needed for sending notification about alarm state.
7. Finally, we need to choose the Create Alarm.

So its completed. Now the alarm is created for our selected custom metrics.

Finished!

Now the alarm will be listed out under the selected state in our AWS panel. Now we need to select an alarm from the list seen and we can see the details and history of our alarm.

Working With Thin Controller And Fat Model Concept In Laravel

Models and controllers are one of the most essential programming handlers in the Laravel MVC framework, and both are used vastly for different functional operations. Models in Laravel are created inside the app folder and are mostly used to interact with the database using Eloquent ORM, while the controllers are located inside the directory App/Http/Controllers.

As a programmer, you should have the knowledge how to keep the balance in between the programming usage of Models and controllers. As which one should be more utilized for allowing functional tasks in applications deployed on any PHP MySQL hosting.


What is the Concept of Thin Controller and FAT Models


The concept of the thin controller and fat model is that we do less work in our controllers and more work in our models. Like we use our controllers to validate our data and then pass it to the models. While in models, we define our actual functional logic and main coding operations of the desired application. This code structuring process is also a very basic concept of MVC and also the differentiating factor from the conventional complex programming which we mistakenly ignore sometimes.


Why FAT Controllers Are Bad For Handling Code


Controllers are always meant to be defined short and concise, and it should only be used for receiving requests and return responses to it. Anything else further should be programmed in Models, which is actually made for main functional operations.

Placing functional logic in controllers can be bad for many reasons for your applications deployed on anyhosting for PHP. As it not only makes code structure long but also makes it complex sometimes. Further placing code in Controllers is also not recommended because if same functionality is needed somewhere else in route, then pulling out the whole code from their becomes difficult and so its reusability in the application.

Though Laravel is an MVC framework while developing on laravel, we sometimes ignore this and write mostly all our code including the extending of App\Model and all our functional logic in controller route methods. What we can do here is we can create a sub model of our parent model. For example, our parent model is User then we can create another sub model of username in CustomerModel if you are using the same User model for all types of users. In this model, we will write all the logic related to user type Customer.

So now let's take an example of my existing blog creating comment system with laravel and vuejs. In that article, you can see I have made so much mess in my controller methods. Mostly, I have written all my comments logic in my methods, so to shorten that let's clean them in this article. Inside app folder, I will create a new file with name CommentModel.php. Inside this file, I will write my whole logic for comment functions. This is my basic file:


<?php
namespace App;

use App\Comment;
use App\CommentVote;
use App\CommentSpam;
use App\User;
use Auth;

class CommentModel
{


}

?>



Right now it contains no function but has the reference of all my models which I required for this model. Let's first add a function namedgetallcomments passing$pageId as a parameter inside it. The function will get all the comments for the given page:


public function getAllComments($pageId)
{
$comments = Comment::where('page_id',$pageId)->get();

$commentsData = [];


foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$replies = $this->replies($key->id);
$photo = $user->first()->photo_url;
$reply = 0;
$vote = 0;
$voteStatus = 0;
$spam = 0;
if(Auth::user()){
$voteByUser = CommentVote::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();


if($voteByUser){
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if($spamComment){
$spam = 1;
}
}


if(sizeof($replies) > 0){
$reply = 1;
}

if(!$spam){
array_push($commentsData,[
"name" => $name,
"photo_url" => (string)$photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"reply" => $reply,
"votedByUser" =>$vote,
"vote" =>$voteStatus,
"spam" => $spam,
"replies" => $replies,
"date" => $key->created_at->toDateTimeString()
]);
}


}
$collection = collect($commentsData);
return $collection->sortBy('votes');
}



Now I will create another function namedreplies which takes$commentId as a parameter. The function is more or less programmed in the same manner as the upper function get all comments.


protected function replies($commentId)
{
$comments = Comment::where('reply_id',$commentId)->get();
$replies = [];



foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$photo = $user->first()->photo_url;

$vote = 0;
$voteStatus = 0;
$spam = 0;


if(Auth::user()){
$voteByUser = CommentVote::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();

if($voteByUser){
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if($spamComment){
$spam = 1;
}
}
if(!$spam){


array_push($replies,[
"name" => $name,
"photo_url" => $photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"votedByUser" => $vote,
"vote" => $voteStatus,
"spam" => $spam,
"date" => $key->created_at->toDateTimeString()
]);
}




}


$collection = collect($replies);
return $collection->sortBy('votes');
}



Now lets create a functioncreate comment which passes$array as a parameter in it:


public function createComment($arary)
{
$comment = Comment::create($array);


if($comment)
return [ "status" => "true","commentId" => $comment->id ];
else
return [ "status" => "false" ];
}



Similarly, Now I will create all the function for comment in myCommentModel, so that all the functions gets accumulated in one model.


<?php
namespace App;

use App\Comment;
use App\CommentSpam;
use App\CommentVote;
use App\User;
use Auth;

class CommentModel
{
public function getAllComments($pageId)
{
$comments = Comment::where('page_id', $pageId)->get();

$commentsData = [];

foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$replies = $this->replies($key->id);
$photo = $user->first()->photo_url;
$reply = 0;
$vote = 0;
$voteStatus = 0;
$spam = 0;
if (Auth::user()) {
$voteByUser = CommentVote::where('comment_id', $key->id)->where('user_id', Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id', $key->id)->where('user_id', Auth::user()->id)->first();

if ($voteByUser) {
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if ($spamComment) {
$spam = 1;
}
}

if (sizeof($replies) > 0) {
$reply = 1;
}

if (!$spam) {
array_push($commentsData, [
"name" => $name,
"photo_url" => (string) $photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"reply" => $reply,
"votedByUser" => $vote,
"vote" => $voteStatus,
"spam" => $spam,
"replies" => $replies,
"date" => $key->created_at->toDateTimeString(),
]);
}

}
$collection = collect($commentsData);
return $collection->sortBy('votes');
}

protected function replies($commentId)
{
$comments = Comment::where('reply_id', $commentId)->get();
$replies = [];

foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$photo = $user->first()->photo_url;

$vote = 0;
$voteStatus = 0;
$spam = 0;

if (Auth::user()) {
$voteByUser = CommentVote::where('comment_id', $key->id)->where('user_id', Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id', $key->id)->where('user_id', Auth::user()->id)->first();

if ($voteByUser) {
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if ($spamComment) {
$spam = 1;
}
}
if (!$spam) {

array_push($replies, [
"name" => $name,
"photo_url" => $photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"votedByUser" => $vote,
"vote" => $voteStatus,
"spam" => $spam,
"date" => $key->created_at->toDateTimeString(),
]);
}

}

$collection = collect($replies);
return $collection->sortBy('votes');
}

public function createComment($arary)
{
$comment = Comment::create($array);

if ($comment) {
return ["status" => "true", "commentId" => $comment->id];
} else {
return ["status" => "false"];
}

}

public function voteComment($commentId, $array)
{
$comments = Comment::find($commentId);
$data = [
"comment_id" => $commentId,
'vote' => $array->vote,
'user_id' => $array->users_id,
];

if ($array->vote == "up") {
$comment = $comments->first();
$vote = $comment->votes;
$vote++;
$comments->votes = $vote;
$comments->save();
}

if ($array->vote == "down") {
$comment = $comments->first();
$vote = $comment->votes;
$vote--;
$comments->votes = $vote;
$comments->save();
}

if (CommentVote::create($data)) {
return true;
}

}

public function spamComment($commentId, $array)
{
$comments = Comment::find($commentId);

$comment = $comments->first();
$spam = $comment->spam;
$spam++;
$comments->spam = $spam;
$comments->save();

$data = [
"comment_id" => $commentId,
'user_id' => $array->users_id,
];

if (CommentSpam::create($data)) {
return true;
}

}
}
?>



Now we have all our required methods inCommentModel. So now let's clean upCommentController which is currently bit complex and lengthy in code structure. As right nowCommentController look like this:


<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Comment;
use App\CommentVote;
use App\CommentSpam;
use App\User;
use Auth;

class CommentController extends Controller
{



public function index($pageId)
{
$comments = Comment::where('page_id',$pageId)->get();

$commentsData = [];




foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$replies = $this->replies($key->id);
$photo = $user->first()->photo_url;
$reply = 0;
$vote = 0;
$voteStatus = 0;
$spam = 0;
if(Auth::user()){
$voteByUser = CommentVote::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();


if($voteByUser){
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if($spamComment){
$spam = 1;
}
}


if(sizeof($replies) > 0){
$reply = 1;
}

if(!$spam){
array_push($commentsData,[
"name" => $name,
"photo_url" => (string)$photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"reply" => $reply,
"votedByUser" =>$vote,
"vote" =>$voteStatus,
"spam" => $spam,
"replies" => $replies,
"date" => $key->created_at->toDateTimeString()
]);
}


}
$collection = collect($commentsData);
return $collection->sortBy('votes');
}

protected function replies($commentId)
{
$comments = Comment::where('reply_id',$commentId)->get();
$replies = [];



foreach ($comments as $key) {
$user = User::find($key->users_id);
$name = $user->name;
$photo = $user->first()->photo_url;

$vote = 0;
$voteStatus = 0;
$spam = 0;


if(Auth::user()){
$voteByUser = CommentVote::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();
$spamComment = CommentSpam::where('comment_id',$key->id)->where('user_id',Auth::user()->id)->first();

if($voteByUser){
$vote = 1;
$voteStatus = $voteByUser->vote;
}

if($spamComment){
$spam = 1;
}
}
if(!$spam){


array_push($replies,[
"name" => $name,
"photo_url" => $photo,
"commentid" => $key->id,
"comment" => $key->comment,
"votes" => $key->votes,
"votedByUser" => $vote,
"vote" => $voteStatus,
"spam" => $spam,
"date" => $key->created_at->toDateTimeString()
]);
}




}


$collection = collect($replies);
return $collection->sortBy('votes');
}


public function store(Request $request)
{
$this->validate($request, [
'comment' => 'required',
'reply_id' => 'filled',
'page_id' => 'filled',
'users_id' => 'required',
]);
$comment = Comment::create($request->all());
if($comment)
return [ "status" => "true","commentId" => $comment->id ];
}


public function update(Request $request, $commentId,$type)
{
if($type == "vote"){


$this->validate($request, [
'vote' => 'required',
'users_id' => 'required',
]);

$comments = Comment::find($commentId);
$data = [
"comment_id" => $commentId,
'vote' => $request->vote,
'user_id' => $request->users_id,
];

if($request->vote == "up"){
$comment = $comments->first();
$vote = $comment->votes;
$vote++;
$comments->votes = $vote;
$comments->save();
}

if($request->vote == "down"){
$comment = $comments->first();
$vote = $comment->votes;
$vote--;
$comments->votes = $vote;
$comments->save();
}

if(CommentVote::create($data))
return "true";
}

if($type == "spam"){


$this->validate($request, [
'users_id' => 'required',
]);

$comments = Comment::find($commentId);


$comment = $comments->first();
$spam = $comment->spam;
$spam++;
$comments->spam = $spam;
$comments->save();

$data = [
"comment_id" => $commentId,
'user_id' => $request->users_id,
];

if(CommentSpam::create($data))
return "true";
}
}


public function destroy($id)
{
}
}?>



After cleaning up the controller it will look much simpler and easy to understand like this:


<?php

namespace App\Http\Controllers;

use App\CommentModel;
use Illuminate\Http\Request;

class CommentController extends Controller
{

private $commentModel = null;
private function __construct()
{
$this->commentModel = new CommentModel();
}


public function index($pageId)
{
return $this->commentModel->getAllComments($pageId);
}


public function store(Request $request)
{
$this->validate($request, [
'comment' => 'required',
'reply_id' => 'filled',
'page_id' => 'filled',
'users_id' => 'required',
]);
return $this->commentModel->createComment($request->all());
}


public function update(Request $request, $commentId, $type)
{
if ($type == "vote") {

$this->validate($request, [
'vote' => 'required',
'users_id' => 'required',
]);

return $this->commentModel->voteComment($commentId, $request->all());
}

if ($type == "spam") {

$this->validate($request, [
'users_id' => 'required',
]);

return $this->commentModel->spamComment($commentId, $request->all());
}
}

}
?>




Wrap Up!


So Isn't it looking much cleaner and simpler to understand now? This is what actually a thin controller and fat model looks like. We have all our logic related to Comment system programmed in ourCommentModel and our controller is now just used to transfer data from the user to our model and returning the response which is coming from our model.

So this is how the structuring of the thin controller and fat model is made. Give your thoughts in the comments below.

Why Cloudways is the Perfect Managed Hosting for PHP Applications

The following is a sponsored blogpost by Cloudways


Developing an application is not the sole thing you should bank on. You must strive to find the best hosting solution to deploy that application also. The application’s speed is dependent on the hosting provider, that is why I always advise you to go for the best hosting solution to get the ultimate app performance.

Now a days, it is a big challenge to choose any web hosting, as each hosting has its own pros and cons which you must know, before considering it finally for the deployment. I don’t recommend shared hosting for PHP/Laravel based applications, because you always get lot of server hassles like downtime, hacking, 500 errors, lousy support and other problems that are part and parcel of shared hosting.

For PHP applications, you must focus on more technical aspects like caching, configs, databases, etc. because these are essential performance points for any vanilla or framework-based PHP application. Additionally, if the app focuses on user engagement (for instance, ecommerce store), the hosting solution should be robust enough to handle spikes in traffic.

Here, I would like to introduce Cloudways PHP server hosting to you which provides easy, developer and designer friendly managed hosting platform. With Cloudways, you don't need to focus on PHP hosting, but must focus on building your application. You can easily launch cloud servers on five providers including DigitalOcean, Linode, Vultr, AWS and GCE.


Cloudways ThunderStack


Being a developer, you must be familiar with the concept of stack - an arrangement of technologies that form the underlying hosting solution.

To provide a blazing fast speed and a glitch-free performance, Cloudways has built a PHP stack, known as ThunderStack. This stack consists of technologies that offer maximum uptime and page load speed to all PHP applications. Check out the following visual representation of ThunderStack and the constituent technologies:


alt_text


As you can see, ThunderStack comprises of a mix of static and dynamic caches with two web servers, Nginx and Apache. This combination ensures the ultimate experience for the users and visitors of your application.


Frameworks and CMS


The strength and popularity of PHP lies in the variety of frameworks and CMS it offers to the developers. Realizing this diversity, Cloudways offers a hassle-free installation of major PHP frameworks including Symfony, Laravel, CakePHP, Zend, and Codeigniter. Similarly, popular CMS such as WordPress, Bolt, Craft, October, Couch, and Coaster CMS - you can install these with the 1-click option. The best part is that if you have a framework or CMS that is not on the list, you can easily install it through Composer.


1-Click PHP Server & Application Installation


Setting up a stack on an unmanaged VPS could take an entire day!

When you opt for Cloudways managed cloud hosting, the entire process of setting up the server, installation of core PHP files and then the setup of the required framework is over in a matter of minutes.

Just sign up at Cloudways, choose your desired cloud provider, and select the PHP stack application.


alt_text


As you can see, your LAMP stack is ready for business in minutes.

Many PHP applications fail because essential services are either turned off or not set up properly. Cloudways offers a centralized location where you can view and set the status of all essential services such as:



* Apache
* Elasticsearch
* Memcached
* MySQL
* PHP-FPM
* Nginx
* New Relic
* Redis
* Varnish


alt_text


Similarly, you can manage SMTP add-ons without any fuss.


Staging Environment


With Cloudways, you can test your web applications for possible bugs and errors before taking it live.

Using the staging feature, developers can first deploy their web sites on test domains where they can analyze the applications performance and potential problems. This helps site administrators to fix those issues timely and view the application performance in real-time.

A default sub domain comes pre-installed with the newly launched application, making it easy for the administrators to test the applications on those testing subdomains. Overall, it's a great feature which helps developers know about the possible errors that may arise during the live deployment.

alt_text

Pre-Installed Composer & Git


PHP development requires working with external libraries and packages. Suppose you are working with Laravel and you need to install an external package. Since Composer has become the standard way of installing packages, it comes preinstalled on the Cloudways platform. Just launch the application and start using Composer in your project.

Similarly, if you are familiar with Git and maintain your project on GitHub or BitBucket, you don’t need to worry about Git installation. Git also comes pre-configured on Cloudways. You can start running commands right after application launch.


Cloudways MySQL Manager


When you work with databases in PHP, you need a database manager. On the Cloudways platform, you will get a custom-built MySQL manager, in which you can perform all the tasks of a typical DB manager.

alt_text


However, if you wish to install and use another database manager like PHPMyAdmin, you can install it by following this simple guide on installing PHPMyadmin.


Server & Application Level SSH


If you use Linux, you typically use SSH for accessing the server(s) and individual applications. A third-party developer requires application and server level access as per the requirements of the client. Cloudways offers SSH access to fit the requirements of the client and users.

alt_text


PHP-FPM, Varnish & Cron Settings


Cloudways provides custom UI panel to set and maintain PHP-FPM and Varnish settings. Although the default configuration is already in place, you can easily change all the settings to suit your own, particular development related requirements. In Varnish settings, you can define URL that you want to exclude from caching. You can also set permissions in this panel.

alt_text


Cron job is a very commonly used component of PHP application development process. On Cloudways platform, you can easily set up Cron jobs in just a few clicks. Just declare the PHP script URL and the time when the script will run.

alt_text


Cloudways API & Personal Assistant Bot


Cloudways provides an internal API that offers all important aspects of the server and application management. Through Cloudways API, you can easily develop, integrate, automate, and manage your servers and web apps on Cloudways Platform using the RESTful API. Check out some of the use cases developed using Cloudways API. You just need your API key and email for authentication of the HTTP calls on API Playground and custom applications.

alt_text


Cloudways employs a smart assistant named CloudwaysBot to notify all users about server and application level issues. CloudwaysBot sends the notifications on pre-approved channels including email, Slack and popular task management tools such as Asana and Trello.


Run Your APIs on PHP Stack


Do you have your own API which you want to run on the PHP stack? No problem, because you can do that, too with Cloudways! You can also use REST API like Slim, Silex, Lumen, and others. You can use APIs to speed up performance and require fast servers with lots of resources. So, if you think that your API response time is getting slower due to the large number of requests, you can easily scale your server(s) with a click to address the situation.


Team Collaboration


When you work on a large number of applications with multiple developers, you need to assign them on any specific application. Cloudways provides an awesome feature of team collaboration through which you can assign developers to specific application and give access to them. You can use this tool to assign one developer to multiple applications. Through team feature, you can connect the team together and work on single platform. Access can be of different type; i.e. billing, support and console. You can either give the full access or a limited one by selecting the features in Team tab.

alt_text


Final Words


Managed cloud hosting ensures that you are not bothered by any hosting or server related issues. For practical purposes, this means that developers can concentrate on writing awesome code without worrying about underlying infrastructure and hosting related issues. Do sign up and check out Cloudways for the best and the most cost-effective cloud hosting solution for your next PHP project!
