PHP for the Web is a terrific introduction on how to use modern PHP effectively. While there is a lot of material out there about building applications with PHP, most of them focus on using a framework like Laravel or Symfony. By working with pure PHP, you will be able to focus on the core ideas instead of how a particular framework implements them.

In this course, you will learn how to use multiple web technologies like POST requests, forms, sessions, and redirects to build a CRUD application with an authentication system.

By the end, you will have all the ingredients at your disposal to go out and build stunning, dynamic PHP web applications.

PHP for the Web: Learn PHP without a Framework

# Array of key-value pairs
The PHP server has a built-in mechanism that takes the `Cookie` header from the request, processes its contents, and produces a nice array of key/value pairs.
The array is a superglobal variable, just like `$_GET`  and `$_POST`.
This one is called `$_COOKIE`.

Let's use the `name` cookie in `random.php` to personalize the page a bit:

<h1>Your lucky number is: <?php echo $randomInt; ?></h1>
<?php if ($randomInt > 5) { ?>
    <h2>Nice, <?php
        echo htmlspecialchars($_COOKIE['name'], ENT_QUOTES);
    ?>!</h2>
<?php } ?>

Reload the page a few times until it shows a random number higher than 5, after which you should see your name on the screen.

Let's see how it works right away. 

# Array of key-value pairs
The PHP server has a built-in mechanism that takes the `Cookie` header from the request, processes its contents, and produces a nice array of key/value pairs.
The array is a superglobal variable, just like `＄_GET`  and `＄_POST`.
This one is called `＄_COOKIE`.

Let's use the `name` cookie in `random.php` to personalize the page a bit:
