How can PHP utilize the $_GET superglobal array to retrieve parameters from a URL and display relevant information?

To retrieve parameters from a URL using the $_GET superglobal array in PHP, you can access the values passed through the URL query string. This allows you to dynamically display relevant information based on the parameters provided in the URL. 

<?php
// Retrieve parameters from the URL using $_GET superglobal array
if(isset($_GET['param1']) && isset($_GET['param2'])) {
    $param1 = $_GET['param1'];
    $param2 = $_GET['param2'];

    // Display relevant information based on the parameters
    echo "Parameter 1: " . $param1 . "<br>";
    echo "Parameter 2: " . $param2 . "<br>";
} else {
    echo "Parameters not provided in the URL.";
}
?>
