PHP & Web Development Blogs

Recently I was faced with a task to post data from a .csv file to an external REST API. I’m just going to log in to this article about what I did to get the job done.

Let’s start by creating a template for uploading the file. For this article’s sake, lets make the changes in the dashboard.blade.php file.

<form method="post" enctype="multipart/form-data"> @csrf <div class="custom-file"> <input type="file" accept=".csv" name="excel" class="custom-file-input" id="customFile" /> <label class="custom-file-label" for="customFile">Choose file</label	> </div> <div> <button type="submit" class="btn btn-primary btn-sm" style="margin-top: 10px"	>Submit> </div>

</form>

Note : Don’t forget to add enctype=”multipart/form-data”!



Once the user has submitted the file, we need a new router to process the file and send its content to the REST API. Let’s start by creating a Controller.

php artisan make:controller UploadController

Now in the web.php file,

Route::post('/upload', [UploadController::class, 'upload'])->name('upload')->middleware('auth');

In the UploadController.php , create a function named upload. We will be writing all the code inside this function. Also, we need an action for the form.

<form method="post" action="{{route('upload')}}" enctype="multipart/form-data">

Now inside the upload function, we need to get the submitted file and parse its contents.

Get the submitted file,

$file = $request->file('excel');

Parse the submitted file,

if (($handle = fopen($file, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { ..... }

}

We will be using a dummy REST API to create users — https://reqres.in/api/users. This is the request body required to create a user.

{ "name": "test", "job": "test"

}

Keeping this in mind, we will create a sample .csv template to be submitted. The fields need to be two, namely Name and Job.



We need to send the values from this file as the request body to the API. So let’s add the code to loop through the content of this file.

if (($handle = fopen($file, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { Http::post('https://reqres.in/api/users', [ 'name' => $data[0], 'job' => $data[1], ]); }

}

This will create each student for each row of the file. But we don’t need to send the data of the first row of the file.

Full code:

public function upload(Request $request){ $file = $request->file('excel'); if($file){ $row = 1; $array = []; if (($handle = fopen($file, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { if($row > 1){ Http::post('https://reqres.in/api/users', [ 'name' => $data[0], 'job' => $data[1], ]); array_push($array,$data[0]); } $request->session()->flash('status', 'Users '.implode($array,", ").' created successfully!'); $row++; } } }else{ $request->session()->flash('error', 'Please choose a file to submit.'); } return view('dashboard');

}

This will post the data starting from the second row of the file, display a success message once the users are created, and an error message if the submit button is clicked without choosing a file.

Full template:

<div class="container max-w-7xl mx-auto sm:px-6 lg:px-8" style="width: 50%"> @if (session('status')) <div class="alert alert-success"> {{ session('status') }} </div> @endif @if (session('error')) <div class="alert alert-error"> {{ session('error') }} </div> @endif <form action="{{route('upload')}}" method="post" enctype="multipart/form-data"> @csrf <div class="custom-file"> <input type="file" accept=".csv" name="excel" class="custom-file-input" id="customFile" /> <label class="custom-file-label" for="customFile">Choose file</label> </div> <div> <button type="submit" class="btn btn-primary btn-sm" style="margin-top: 10px">Submit</button> </div> </form>

</div>

That’s it, thanks for reading :)

PHP, by all means, is an immensely powerful language!



We may fall short of words, but there won't come any end to its qualities. The endless functionalities and possibilities of this server-side scripting language have managed to get it a strong and supportive community of PHP programmers on a global level. At present, PHP powers more than half on websites and applications on the internet.


Do you know what makes PHP so praiseworthy?



It is the simplicity, easy programming structure, and developer-friendly web functionalities that are to be credited to turn PHP into one of the top programming languages. You can create highly interactive and dynamic websites and applications with desired results by making use of PHP.



However, coding often could be a tough and tedious task to accomplish. As a solution to this, you get built-in PHP libraries that optimize the process of coding for maximum productivity.

But what are these libraries?

That's exactly what you will find out as you move ahead in this article, a list of top 12 PHP libraries capable of leading the development process in an intended manner.



So, without waiting any further, let's move ahead to learn about PHP libraries in-depth.

PChart

PChart is a PHP library assisting with the generation of text data in the form of something more appealing to the eyes and known as visual charts.



You can use this library to represent data as bar charts, pie charts, and many more different formats. The PHP script here utilizes SQL queries to put data in the impressive charts or graphs form.

Mink

Another well-known in the list of PHP libraries is Mink. It allows you to keep an eye on if a proper interaction is happening between your web apps and the browser. Eliminating the API differences between the two types of browser emulators, Mink offers an authentic testing environment for you. It also supports PHPUnit, Behat, and Symfony2.

Monolog

Monolog is a PHP logging library that helps you with saving logs to the specified locations by sending them to set files, sockets, inboxes, databases, or other web services. The use of the PSR-3 interface permits to type-hint logs in counter to your libraries that maintain optimum interoperability.

Hoa

This modular, extensible, and structured set of PHP libraries we know as Hoa establishes a link between the research and the industry.



It recommends essential paradigms, mechanisms, and algorithms for building the reliability of a site. Many PHP developers in different parts of the world use Hoa for ideal PHP development.

Guzzle

Guzzle is an HTTP client library for PHP that enables you to send HTTP requests to combine with web services.



It offers a simple interface that makes the development of query strings, POST requests, HTTP cookies, and many other attributes possible. You can also use Guzzle to send synchronous and asynchronous requests from the similar interface.

Ratchet

If your need is to develop real-time, two-directional apps between clients and servers over WebSockets, Ratchet is the PHP library you need to do it effectively.



Creating event-driven apps with Ratchet is a rapid, simple, and easy job to do!

Geocoder

Geocoder is a library to create applications that are very well geo-aware.



With Geocoder, there is an abstraction layer that helps with geocoding manipulations.



It is further split into two parts, known as HttpAdapter and Provider.

ImageWorkshop

ImageWorkshop is an open-source PHP library letting you work over the manipulation of images with layers. You can crop, resize, add watermarks, create thumbnails, and so much more. You can also enhance the images on the sites.

PhpThumb

phpThumb is the library specialized at handling the work associated with creating thumbnails with minimal coding. Accepting every image source type and image formats, it makes you do a lot ranging from rotating or cropping to watermarking or defining the image quality.

Parody

This simple library we know as Parody is used to copy classes and objects. It also provides results for method calls, acquiring properties, instantiating objects, and more. Sequential method chaining is used by Parody to produce defining class structures.

Imagine

This object-oriented PHP library is meant for working with images along with manipulating them. The often adopted operations such as resizing, cropping, and applying filters happen instantly and relatively well with Imagine.



With Imagine, you get a color class that forms the RGB values of any given color. Draw shapes like arc, ellipse, line, etc. with the features available.

PhpFastCache

PhpFastCache is an open-source PHP library that makes caching feasible. Coming as a single-file, it can be integrated within a matter of minutes.



Caching methods supported by PhpFastCache involve apc, memcache, memcached, wincache, pdo, and mpdo.


The Bottom Line




It's not about what extra difference these libraries make; it's about what significant individual contributions these libraries make for a final desired PHP app or website.



A PHP programmer, too, agrees with these libraries' benefits.



It's your time now to try and believe!

People that visit your website face an invisible threat each time they log on. Small businesses are especially vulnerable to digital data breaches, and that can change the way your customers feel about you. But, although you cannot stop hackers from trying, there are things you can do as a business owner to make your website a safer experience for everyone. Keep reading for tips.

Mature digitally.

You may be ahead of the times when it comes to products and services, but, chances are, your website hasn't fully kept up. It's time to learn all you can about the internet and digital security. If you are already somewhat tech savvy, a PHP Security Course from Nomad PHP can help you better understand everything from cryptography to website error messages.

Adapting to today's digital environment means transforming your website to quickly and easily identify threats via machine learning and network monitoring. And, as Upwork explains, digital maturity not only keeps your website safe, but adopting this mindset can also increase your efficiency and accuracy by reducing human errors.

Understand the threats.

It is not enough to simply keep up with your website, you also have to understand the types of threats that are out there. You're likely familiar with ransomware and phishing, but, it's also a good idea to know how a website can get hacked. Your site's content management system and vulnerabilities within your operating system are all weak points that hackers can easily identify.

Insist on security measures.

When customers log into your website, they input their credentials. Each time they do so, you can best protect their information by keeping your systems up to date. You'll also want to ensure that your site is hosted on a secure service and that you have an SSL certificate installed.

If you are not already, have your IT department or managed IT services perform regular website security checks. PhoenixNAP, an IT services provider, notes that those websites working via WordPress should also be safely outfitted with the most recent security plug-ins.

Eliminate spam.

If your website allows for comments that are not manually approved, anyone on the internet can post. This leaves it open for hackers and other unscrupulous individuals to comment with spam and malicious links that your customers may inadvertently click on. While many of these simply exist as a way for the commenter to drive traffic to another website, others are designed to draw your readers' attention, gain their trust, and access their personal information.

Prioritize passwords.

Your customers' passwords are the keys by which they open the door to your website. Unfortunately, many people do not treat them with as much care as they do the keys they use in the non-digital world.

It's true, passwords can be a pain, but you are not doing yourself or your customers any favors by allowing simple one-word passcodes to access your site. Instead, design your site to require a strong password. How-To Geek asserts that this will have a minimum of 12 characters and include a combination of upper and lower case letters, symbols, and numbers.

While you will likely rely on your IT experts to secure your website, the truth is that it is ultimately up to you to ensure this is done. So even if you are not a digital mastermind, knowing all you can about web security can help you be a better business owner. Your customers will be safer, and a secure website is just one way to strengthen your business's online presence and keep up with today's -- and tomorrow's -- technology.

Welcome back! If you're new to this series have a look at Part 1 here

Today we are going to beef things up a bit and we will focus on the backend and some key CMS functionality.

It's time to get excited, this is where you'll start to see your barebones structure morph into something extraordinary!

Tired of my intro? That's ok! Let's jump into it!

Getting the DB on board

Before we delve into this, it's imperative that we take a minute and plan things out.

The database tables that are vital to any CMS are the menu, the user table, and the content table.

Our menu table will start of as follows:

CREATE TABLE 'mydbname'.'menus' ( 'ID' INT(11) NOT NULL AUTO_INCREMENT , 'menuname' VARCHAR(100) NOT NULL , 'item' VARCHAR(50) NOT NULL , 'itemlink' VARCHAR(100) NOT NULL , PRIMARY KEY ('ID')) ENGINE = MyISAM COMMENT = 'menu table';

Let's break this down a bit.

In the SQL above, we're creating a new table called menus.

Essentially our structure looks like this:

ID | Menuname | Item | Itemlink

Our ID field is our unique identifier (our PRIMARY KEY).

Tip: Remember, you can use raw SQL or a tool like PhpMyAdmin to create your db tables/execute SQL queries.

Next up is our user table.

CREATE TABLE 'mydbname'.'users' ( 'ID' INT(11) NOT NULL AUTO_INCREMENT , 'username' VARCHAR(100) NOT NULL , 'password' VARCHAR(50) NOT NULL , 'email' VARCHAR(100) NOT NULL , PRIMARY KEY ('ID')) ENGINE = MyISAM COMMENT = 'user table';

Visually represented this structure looks like this:

ID | Username | Password | Email

Our ID field is our unique identifier.

And finally, our content table modifications. You probably remember creating a rudimentary content table in Part 1 of the series.

ALTER TABLE 'mydbname'.'content' ADD content_type VARCHAR(50);

Yep, you guessed right, in the above statement we are altering our content table and adding a new field called content type.

Our new table structure now looks like this:

ID | Title | Content | Author | Content Type

Planning to Add to the Backend

Next , we're going to add a menu section, an add user section, and we'll also modify our content section.

Let's do this! reate a file called menus.php in your backend folder.

Next, code a HTML form to save your menu data.

The form needs the following fields:

Menu Name (we called this menuname in our db table).

Menu Item Name (we called this item in our db table).

Menu Link (we called this itemlink in our db table).

Try to follow Part 1 to do this on your own.

If you get a little stuck, that's ok. You can also follow the example below:

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

<input type="text" name="menuname" class="mytextbox" placeholder="Menu Name" required />

<input type="text" name="item" class="mytextbox" placeholder="Item" required />

<input type="text" name="itemlink" class="mytextbox" placeholder="Item Link" required />

<input type="submit" value="Save Menu Item" name="savemenu" class="mybutton"/>

</form>
 

Notice the use of CSS classes? The gravy!

This will come in handy in our next tutorial.

Next, let's add the form processing code as we need to save these fields to the database. Remember to use the sanitization technique you learned in Part 2.

Add this above your <form> tag.

<?php

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

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

if ($letsconnect->connect_error) {

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

}else{

$menuname = $letsconnect ->real_escape_string($_POST['menuname']);

$item = $letsconnect -> real_escape_string($_POST['item']);

$itemlink = $letsconnect->real_escape_string($_POST['itemlink']);

$sql = "INSERT INTO menus(menuname,item,itemlink) VALUES ('".$menuname."', '".$item."', '".$itemlink."')";

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

echo "Your data was saved successfully!";

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

} $letsconnect->close();

}

}

?>

Ok phew, the menu data capturing section is done.

Let's move on to the user data capturing section, and modify the content capturing screen.

Repeat the steps above and create these two screens. Remember to keep an eye out for our database field names that we defined earlier! If you get stuck, look at the end result below:

Create adduser.php in your backend folder.

Create your data capturing form.

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

<input type="text" name="username" class="mytextbox" placeholder="Username" required/>

<input type="password" name="password" class="mytextbox" placeholder="Password" required />

<input type="email" name="email" class="mytextbox" placeholder="Email" required />

<input type="submit" value="Save Menu Item" name="saveuser" class="mybutton"/>

</form>

Add your PHP processing code, remember the security!

Add this above your <form> tag.

<?php

if(isset($_POST[‘saveuser])){

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

if ($letsconnect->connect_error) {

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

}else{

$menuname = $letsconnect -> real_escape_string($_POST[‘username']);

$item = $letsconnect -> real_escape_string($_POST[‘password']);

$itemlink = $letsconnect -> real_escape_string($_POST[‘email']);

$sql = "INSERT INTO menus(username,password,email) VALUES ('".$username."', '".$password."', '".$email."')";

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

echo "Your data was saved successfully!";

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

} $letsconnect->close();

}

}

?>

Please note that I will be covering Password security in the tutorials that follow.

Make sure that you are using your localhost server to complete this tutorial series. Do not publish your work until you complete this series.

Lastly, let's move to our content capturing screen which is currently found in index.php in the backend folder.

We will be changing this to a more professional dashboard in the tutorials that follow!
Our current file looks like this:

<html>

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

<body>

<?php

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

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

if ($letsconnect->connect_error) {

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

}else{

$title = $letsconnect -> real_escape_string($_POST['title']);

$content = $letsconnect -> real_escape_string($_POST['content']);

$author = $letsconnect -> real_escape_string($_POST['author']);

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

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

echo "Your data was saved successfully!";

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

} $letsconnect->close();

}

}

?>

<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>

We need to modify this slightly to include our new field, content_type.

Add the input field in your <form> above the submit button.

<input type="text" name="content_type" placeholder="Content Type" required/>;

Next, add the content_type to the sanitization lineup.

$content_type = $letsconnect->real_escape_string($_POST['content_type']);

Lastly, store this variable to the database by modifying the $sql.

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

Conclusion

Chopping and changing is not always as daunting. Find a rhythm. There are many ways to make cumbersome coding a breeze and we will delve into that in the tutorials to come.

Challenge

Think of ways to test what we just did through retrieving and echoing data from the database.

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.
