How to Get URL Parameter in PHP

Getting GET parameters:

If the URL has GET parameters, so it looks like, for example:

localhost/snippetsdb/?name=Anna

or

localhost/snippetsdb/?name=Anna&age=31

We can simply refer to GET values using $_GET[‘name‘], as in the following example:

<?php
    echo $_GET['name'] . ' is ' . $_GET['age'] . ' years old.';
?>

Getting other URL parameters:

If we don’t have access to GET parameters, we can get all URL parameters using parse_url function. However, in the first parameter we have to specify the URL (or only its parameters) we want to check.

<?php
    $url = parse_url( $_SERVER['REQUEST_URI']);

    var_dump($url);
?>

Output for localhost/snippetsdb/?name=Anna&age=31:

array(2) { ["path"]=> string(12) "/snippetsdb/" ["query"]=> string(16) "name=Anna&age=31" }
