How can parameters passed through the URL be handled and processed in PHP?

When parameters are passed through the URL in PHP, they can be accessed using the $_GET superglobal array. This array contains key-value pairs of the parameters passed in the URL. To handle and process these parameters, you can simply access them by their key in the $_GET array. 

// Example of handling parameters passed through the URL in PHP
if(isset($_GET['param1'])) {
    $param1 = $_GET['param1'];
    
    // Process the parameter as needed
    echo "Parameter 1: " . $param1;
} else {
    echo "No parameter passed in the URL";
}
