What are the key considerations when implementing URL routing in PHP for improved website navigation?

Key considerations when implementing URL routing in PHP for improved website navigation include defining clear and meaningful URLs, organizing routes effectively, handling dynamic parameters, and ensuring proper error handling.

<?php

// Define a simple routing mechanism using a switch statement
$route = $_GET['route'] ?? '';

switch ($route) {
    case 'home':
        include 'home.php';
        break;
    case 'about':
        include 'about.php';
        break;
    case 'contact':
        include 'contact.php';
        break;
    default:
        include '404.php';
        break;
}

?>
