Composer is the way that that PHP developers manage libraries and their dependencies. Previously, developers mainly stuck to existing frameworks. If you were a Symfony developer, you used Symfony and libraries built around it. You didn’t dare cross the line to Zend Framework. These days however, developers focus less on frameworks, and more on the libraries they need to build the project they are working on. This decoupling of projects from frameworks is largely possible because of Composer and the ecosystem that has built up around it.

Like PHP, Composer is easy to get started in, but complex enough to take time and practice to master. The Composer manual does a great job of getting you up and running quickly, but some of the commands are involved enough so that many developers miss some of their power because they simply don’t understand.

I’ve picked out five commands that every user of Composer should master. In each section I give you a little insight into the command, how it is used, when it is used and why this one is important.

1: Require

Sample:

$ composer require monolog/monolog

Require is the most common command that most developers will use when using Composer. In addition to the vendor/package, you can also specify a version number to load along with modifiers. For instance, if you want version 1.18.0 of monolog specifically and never want the update command to update this, you would use this command.

$ composer require monolog/monolog:1.18.0

This command will not grab the current version of monolog (currently 1.18.2) but will instead install the specific version 1.18.0.

If you always want the most recent version of monolog greater than 1.8.0 you can use the > modifier as shown in this command.

$ composer require monolog/monolog:>1.18.0

If you want the latest in patch in your current version but don’t want any minor updates that may introduce new features, you can specify that using the tilde.

$ composer require monolog/monolog:~1.18.0

The command above will install the latest version of monolog v1.18. Updates will never update beyond the latest 1.18 version.

If you want to stay current on your major version but never want to go above it you can indicate that with the caret.

$ composer require monolog/monolog:^1.18.0

The command above will install the latest version of monolog 1. Updates continue to update beyond 1.18, but will never update to version 2.

There are other options and flags for require, you can find the complete documentation of the command here.

2: Install a package globally

The most common use of Composer is to install and manage a library within a given project. There are however, times when you want to install a given library globally so that all of your projects can use it without you having to specifically require it in each project. Composer is up to the challenge with a modifier to the require command we discussed above, global. The most common use of this is when you are using Composer to manage packages like PHPUnit.

$ composer global require "phpunit/phpunit:^5.3.*"

The command above would install PHPUnit globally. It would also allow it to be updated throughout the 5.0.0 version because we specified ~5.3.* as the version number. You should be careful in installing packages globally. As long as you do not need different versions for different projects you are ok. However, should you start a project and want to use PHPUnit 6.0.0 (when it releases) but PHPUnit 6 breaks backwards compatibility with the PHPUnit 5.* version, you would have trouble. Either you would have to stay with PHPUnit 5 for your new project, or you would have to test all your projects to make sure that your Unit Tests work after upgrading to PHPUnit 6.

Globally installed projects are something to be thought through carefully. When in doubt, install the project locally.

3: Update a single library with Composer

One of the great powers of Composer is that developers can now easily keep their dependencies up-to-date. Not only that, as we discussed in tip #1, each developer can define exactly what “up-to-date” means for them. With this simple command, Composer will check all of your dependencies in a project and download/install the latest applicable versions.

$ composer update

What about those times when you know that a new version of a specific package has released and you want it, but nothing else updated. Composer has you covered here too.

$ composer update monolog/monolog

This command will ignore everything else, and only update the monolog package and it’s dependencies.

It’s great that you can update everything, but there are times when you know that updating one or more of your packages is going to break things in a way that you aren’t ready to deal with. Composer allows you the freedom to cherry-pick the packages that you want to update, and leave the rest for a later time.

4: Don’t install dev dependencies

In a lot of projects I am working on, I want to make sure that the libraries I download and install are working before I start working with them. To this end, many packages will include things like Unit Tests and documentation. This way I can run the unit Tests on my own to validate the package first. This is all fine and good, except when I don’t want them. There are times when I know the package well enough, or have used it enough, to not have to bother with any of that.

Many packages create a distribution package that does not contain tests or docs. (The League of Extraordinary Packages does this by default on all their packages.) If you specify the --prefer-dist flag, Composer will look for a distribution file and use it instead of pulling directly from github. Of course if you want want to make sure you get the full source and all the artifacts, you can use the --prefer-src flag.

5: Optimize your autoload

Regardless of whether you --prefer-dist or --prefer-source, when your package is incorporated into your project with require, it just adds it to the end of your autoloader. This isn’t always the best solution. Therefore Composer gives us the option to optimize the autoloader with the --optimize switch. Optimizing your autoloader converts your entire autoloader into classmaps. Instead of the autoloader having to use file_exists() to locate a file, Composer creates an array of file locations for each class. This can speed up your application by as much as 30%.

$ composer dump-autoload --optimize

The command above can be issued at any time to optimize your autoloader. It’s a good idea to execute this before moving your application into production.

$ composer require monolog/monolog:~1.18.0 -o

You can also use the optimize flag with the require command. Doing this every time you require a new package will keep your autoloader up-to-date. That having said, it’s still a good idea to get in the habit of using the first command as a safety net when you roll to production, just to make sure.

BONUS: Commit your composer.lock

After you have installed your first package with composer, you now have two files in the root of your project, composer.json and composer.lock. Of the two, composer.lock is the most important one. It contains detailed information about every package and version installed. When you issue a composer install in a directory with a composer.lock file, composer will install the exact same packages and versions. Therefore, by pulling a git repo on a production server will replicate the exact same packages in production that were installed in development. Of course the corollary of this is that you never want to commit your vendor/ directory. Since you can recreate it exactly, there is no need to store all of that code in your repo.

It is recommended that also commit your composer.json. When you check out your repo into production and do an install, composer will use the composer.lock instead of the composer.json when present. This means that your production environment is setup exactly like your development environment.

A little history

Several years ago I had the distinct privilege of founding Midwest PHP with Jonathan Sundquist. The goal was simple, to bring an affordable PHP conference to Minnesota and the midwest region.

Midwest PHP was created for one simple reason - there weren't a lot of alternatives, especially affordable ones. At the time, your choices were ZendCon in Silicon Valley, php[tek] in Chicago, or Northeast PHP in Boston. While Northeast PHP formed the blueprint of a community conference - it still required a flight and a costly hotel in Boston. I wanted something where local attendees, college students, and those just beginning in their PHP careers could go to learn, network, and become part of the PHP community.

Shortly after Midwest PHP was formed (originally we were using the name PHPFreeze - until Sundquist told me what a horrible idea it was), Adam Culp launched Sunshine PHP which has become one of the top community focused PHP conferences (but still requires that flight and hotel in Miami). Sundquist and I knew that any reasonable developer would still prefer to attend a conference in a blizzard than enjoy the beautiful Floridian weather (ok, that might not be it, but we still understood the need that existed).

After moving to California for my new job, Jonathan Sundquist continued to run Midwest PHP as more community conferences appeared. With his efforts, and the torch being passed to Mike Willbanks, Midwest PHP celebrated it's seventh consecutive year, becoming the longest continuously running PHP conference (if you go by formed date, if you go by actual conference date Sunshine PHP beats us out by a month).

A renewed focus

Because of the incredible work Jonathan and Mike have done, Midwest PHP has stood the test of time - and the peaks and valleys that come with any conference. With the shifts in the PHP community and the sad loss of several community conferences - we realized the need for Midwest PHP is more now than ever, and to meet that need we needed to reimagine the way the conference operated.

We also realized that the best way to make Midwest PHP accessible was to combine forces, creating a seamless partnership between Nomad PHP and Midwest PHP. Through this partnership we're not only able to stream the event to make it more accessible ($19.95/mo), but also expand the conference.

This year, taking place onApril 2-4, 2020 - Midwest PHP will bring together over 800 developers both in-person and virtually! Making this year truly unique, however, and staying with our purpose of helping new developers be part of the PHP community is abrand new, FREE, beginner track. I'm excited to say we will be giving away 200 tickets to those wishing to attend our Beginner or Learn PHP track!!!

We will also work to keep prices as low as possible as we offer our standard PHP tracks (Everyday PHP and PHP Performance & Security) starting at $250/ person, anda brand new enterprise track geared at developers facing challenges at unprecedented scale starting at $450/ person.

Last but not least, it is our goal with the help of our sponsors to include the workshop day as part of your ticket price - allowing you to get one day of in-depth training, and two more full days of sessions. On top of this, we're also excited to make the Nomad PHP and Nomad JS video libraries available for Standard and Enterprise attendees, providing over 220 additional virtual sessions on demand!

For sponsors

Sponsoring a conference is hard. We understand the challenge of gauging ROI, planning travel, and coordinating outreach. With the combined forces of Midwest PHP and Nomad PHP, we're able to offer sponsors unique plans that maximize their investment - while ensuring the funds go back into the event to create an amazing experience for our attendees.

Beyond Midwest PHP's goal to be the largest PHP conference this year - the included Nomad PHP advertising will help you reach a much larger and broader audience, allowing for follow up advertisements and consistent engagement with the PHP community.

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:





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.





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





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.

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.




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.

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.




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.

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.




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.

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!

Your biggest asset is also your biggest risk... your developers

Your business thrives because of the incredible work and innovation of your developers. With simple keystrokes your developers can completely transform your business, add new features, and drive new sales.

But those same keystrokes can take down production, create security back doors, and put your business at risk. That's why it's more important than ever for your team members to be up to speed with the latest technology, especially around performance and security.

Of course, some things are easier said than done - after all everyone is super busy these days. So how can you help keep your team members learning, and putting your business first in the process?

Conference Parties

There's nothing better than attending a PHP or programming conference in person - the chance to meet speakers face to face, to network, the knowledge, and the hallway track. However, many companies aren't able to afford multiple (or even one) conference for their developers - especially ones that require airfare and hotel.

However, that doesn't mean you shouldn't still participate in these conferences. The good news is that roughly once a quarter Nomad PHP streams talks from a conference right to your computer. This means that your team members can all participate in a multi-day conference from the comfort of your office (or their home) - and you can provide this for your team for less than the cost of a single conference ticket!

Make the conference party even more special by providing lunch during the lunch break, bringing in party gifts, having give-aways during the conference, and planning activities during longer breaks for your team.

Since many conferences take place on Friday, not only are you providing invaluable training and an incredible work benefit, but ending the week on a super positive note that your team members will appreciate (and your risk assessment teams will greatly appreciate as new security practices and compliance practices are put into place).

Monthly Lunch and Learns

Every month Nomad PHP offers live virtual talks by the industry's top experts. With talks at 11am Pacific, and 6pm Pacific it's a perfect time to grab a conference room and order a couple pizzas for lunch (or if Eastern, grab some snacks and maybe a beer) and play the monthly meeting on the large screen.

Your team members will have the opportunity to take notes, discuss with each other, and perhaps most importantly ask the speaker real-world questions that directly impact your business, providing tangible solutions to the problems they are facing.

And since every Nomad PHP Pro meeting is recorded, your team members can refer back to the video at any time, watching sections relevant to them or digging in for more information.

Developer Book Club

Encourage your team members to share what they're learning with others, and help build each other up. Not only are you helping grow skills and ensure your team is following the latest best practices, but you're also fostering a mentor-mentality within your team - where each team member feels invested in the growth of other members.

With Nomad PHP you receive a new issue of [php[architect]](/books) each month and have several additional books available to read on demand - providing the latest updates and an invaluable resource to help your book club get started.

Developer Movie Nights

Sometimes we all just want to get away, grab some popcorn, and watch a movie. Similar to lunch and learns, give your developers a night or two where they can get together and watch one of the 250+ training videos available on Nomad PHP. You can even make it a movie marathon!

Whether it's pizza, popcorn, sodas, beers - your team members will have the chance to kick back, relax a bit, build team camaraderie, and learn valuable skills to help your business succeed. Essentially, turning a training day into a fun team-bonding activity.

Learning Path Challenges

Every company has challenges, and areas they need their team members to master. Whether it's DevOps and containerization, security, performance, management, modernization, or soft skills - work with your team to determine what skills will help them succeed and work with your team members to put together video learning paths.

Your team members can watch through these videos on-demand, go back and replay to refresh their knowledge, and work their way towards mastery in the subjects that will help your company succeed.

Certification

Show that you are invested in your developers by helping them earn Professional Certification. These certifications demonstrate that your team members have a fundamental grasp of the technology they are working with and understand when and how to use this technology.

With free certification exams included with Nomad PHP - you no longer have to worry about failed exams or expensive test credits. Your team members can take the exams at their own pace, discover the areas they need to improve, and take the exam again when they are ready. After all, shouldn't the goal of certification be to help your developers learn these skills and prove their expertise?

You can go even further with certifications by having a special company award, framing their certificate, or calling out newly certified developers at team meetings or all-hands.

Learning Incentives/ Rewards

Of course there are even more ways you can help your developers learn new skills, grow their careers, and build loyalty within your company. With Nomad PHP there are numerous ways for your team members to grow their skills, and numerous ways you can reward/ incentivize them - from rewards for the most active learner, to setting goals for learning new skills, to obtaining certifications, to attending streams, to watching videos on-demand. All of these are included with our Professional Nomad PHP Team subscriptions.

It took me quite some time to settle on my first blog post in this series and I found myself thinking about the most requested functionality in my career – The good ‘ol Custom CMS – typically geared towards clients that want a straight forward, secure solution that can be expanded upon in a modular format and that’s their IP.

This will be our starting point. A blank slate to build something epic with clean code and even cleaner design. And in the spirit of building from scratch, I will refrain from using classes or a framework. The main reasoning behind this is to truly get everyone acquainted with and excited about PHP development.

Join me as I transform rudimentary code into something extraordinary that can be morphed into just about any Content, PHP, and MySQL driven project. So without further ado, let’s jump into it!

The bare necessities

If you’re just getting started with development, there’s a nifty bite sized server called UniformServer that will be your best friend throughout your coding career. PHPMyAdmin (an awesome visual db management tool) comes built in so if you’re looking for a work right out of the box solution, this is it.

Alternatively, you can opt for XAMPP or use an alternative server of your choice.

Now here’s where the exciting stuff begins, mapping things out.

I don’t see this done/encouraged often enough. Feel free to grab a piece of paper to logically map out your steps or produce a rough draft of where you’d like this project to go.

In this tutorial, I would like to achieve the following:

DB, DB, Set up your DB.

This requires a bit of planning but let’s start of with the basic structure we need to see this through.

We are going to need a user table and a content table and are a few ways to tackle this.

If you’re using the PHPMyAdmin tool you can create your database, add user permissions (Click on Permissions after creating your database), and create a table with ease.



If you’re like me and prefer to look at good ‘ol SQL then writing an SQL statement is the preferred approach.

CREATE TABLE <code>mydbname</code>.<code>content</code> ( <code>ID</code> INT(11) NOT NULL AUTO_INCREMENT , <code>title</code> VARCHAR(100) NOT NULL , <code>content</code> LONGTEXT NOT NULL , <code>author</code> VARCHAR(50) NOT NULL , PRIMARY KEY (<code>ID</code>)) ENGINE = MyISAM COMMENT = 'content table';

Understanding the SQL statement

In a nutshell we are creating a table with important fields. Namely:

####

ID | Title | Content | Author

#######

The ID field is our unique identifier.Now we can move on to the file structure.

Everything has a place in the file structure game

You can use a structure that speaks to your coding style / memory.

I tend to use the following:



Choose a name for your CMS, which should be placed at the webroot of your localhost/server.

Replicate the folder structure as per the above example.

Next, we’re going to create a basic connection file.

You can create a conn.php file in your root/includes folder.

The connection file will provide crucial information to connect to the database.

Type the following into your conn.php file, remember to include your own database credentials.

<?php

$letsconnect = new mysqli("localhost","dbuser","dbpass","dbname");

?>

Let’s go to the homepage (index.php)

Create a file called index.php at the root of your CMS folder.

I will be adding comments in my code to help you understand what each line does.

Comments are a useful tool for developers to add important notes private to their code.

We need to pull information from the database so it’s imperative that we include our connection file.

<?php

include('includes/conn.php');

if ($letsconnect -> connect_errno) { echo "Error " . $letsconnect -> connect_error;

}else{

$getmydata=$letsconnect -> query("SELECT * FROM content");

foreach($getmydata as $mydata){	echo "Title: ";	echo $mydata['title'];	echo "<br/>";	echo "Content: ";	echo $mydata['content'];	echo "<br/>";	echo "Author: ";	echo $mydata['author'];	echo "<br/>";	echo "<br/>";

}

}

$letsconnect -> close();

?>

Let’s get a (very) basic backend up and running

Create a file called index.php in your backend folder.

We need to create a basic form to capture our data.

Let’s code some HTML!

<html>

<head><title>Backend - Capture Content</title></head>

<body>

<form action="<?php $_SERVER[‘PHP_SELF’];?>" method="post">

<input type="text" name="title" placeholder="Content Title here" required/>

<textarea name="content">Content Here</textarea>

<input type="text" name="author" placeholder="Author" required/>

<input type="submit" value="Save My Data" name="savedata"/>

</form>

</body>

</html>

Next, we need to process the form data.

Type the following just above the

<form> 

tag.

<?php

if(isset($_POST['savedata'])){

include('../includes/conn.php');

if ($letsconnect->connect_error) {

die("Your Connection failed: " . $letsconnect->connect_error);

}else{

$sql = "INSERT INTO content(title,content,author)VALUES ('".$_POST["title"]."', '".$_POST["content"]."', '".$_POST["author"]."')";

if (mysqli_query($letsconnect, $sql)) {

echo "Your data was saved successfully!";

} else { echo "Error: " . $sql . "" . mysqli_error($letsconnect);

} $letsconnect->close();

}

}

?>

Note, this is a basic MySQL query to insert data. However, before using this in production it's important to add proper escaping and security to prevent SQL injections. This will be covered in the next article.

Congrats you made it to the end of tutorial 1!

Test out your creation, modify your content, and play around.

Go to your sitename/index.php to see your frontend after capturing data via sitename/backend/index.php

Conclusion

Coding doesn’t have to be daunting and it’s my aim to divide a complex system into bitesized tutorials so you can truly use the knowledge you’ve acquired in your own projects.
