## $_GET and $_POST
$_GET and $_POST are Superglobal variables in PHP which used to collect data from HTML form and URL.

There are two ways the browser(client) can send information to the web server.

-The GET Method
-The POST Method

*********The GET Method*********
In PHP, the $_GET variable is used to collect values from HTML forms using method get.
Information sent from an HTML form with the GET method is displayed in the browser's address bar, and it has a limit on the amount of information to send.

The example below contains an HTML form with two input fields, and a submit button fot GET Methood:
-----------------------------------------------------------------------------
<html>
<body>

<form action="registration.php" method="get">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html>
-----------------------------------------------------------------------------

When the user clicks on the "Submit button", the URL will be something like this:
localhost/registration.php?name=Alex&email=alex%40example.com

registration.php looks like this:
-----------------------------------------------------------------------------
<html>
<body>

Welcome <?php echo $_GET["name"]; ?>!
Your email address is <?php echo $_GET["email"]; ?>

</body>
</html>

Output:
Welcome Alex!
Your email address is alex@example.com.

-----------------------------------------------------------------------------

*********The POST Method*********
In PHP, the $_POST variable is used to collect values from HTML forms using method post.
Information sent from a form with the POST method is invisible and has no limits on the amount of information to send.

The example below contains an HTML form with two input fields, and a submit button fot POST Methood:
-----------------------------------------------------------------------------
<html>
<body>

<form action="registration.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html>
-----------------------------------------------------------------------------
When the user clicks on the "Submit button", the URL will be something like this:
localhost/registration.php

registration.php looks like this:
-----------------------------------------------------------------------------
<html>
<body>

Welcome <?php echo $_POST["name"]; ?>!
Your email address is <?php echo $_POST["email"]; ?>
