How can PHP handle GET parameters passed through a link?

When a link passes GET parameters to a PHP script, the script can access these parameters using the $_GET superglobal array. To handle these parameters, you can use isset() to check if a specific parameter is set and then access its value from $_GET. You can then use this value in your PHP script as needed. 

if(isset($_GET['param_name'])) {
    $param_value = $_GET['param_name'];
    // Use $param_value in your script
}
