How can PHP be used to differentiate between module requests and module parameters in a URL structure?

To differentiate between module requests and module parameters in a URL structure using PHP, we can use the $_GET superglobal array to access the query parameters in the URL. We can check if a specific parameter exists in the URL to determine if it is a module request or a module parameter.

// Check if a specific parameter exists to differentiate between module requests and module parameters
if(isset($_GET['module'])) {
    // This is a module request
    $module = $_GET['module'];
    // Perform actions based on the module request
} else {
    // This is a module parameter
    $parameter = $_GET['parameter'];
    // Perform actions based on the module parameter
}
