PHP Superglobal - $_GET
Super global variables are built-in variables that are always available in all scopes.
PHP $_GET is a PHP super global variable which is used to collect form data after submitting an HTML form with method="get".
$_GET can also collect data sent in the URL.
Assume we have an HTML page that contains a hyperlink with parameters:
<a href="test_get.php?subject=PHP&web=W3schools.com">Test $GET</a>
When a user clicks on the link "Test $GET", the parameters "subject" and "web" are sent to "test_get.php", and you can then access their values in "test_get.php" with $_GET.
The example below shows the code in "test_get.php":
echo "Study " . $_GET['subject'] . " at " . $_GET['web'];
Tip: You will learn more about $_GET in the PHP Forms chapter.
