What is the concept of routing in PHP and how does it relate to form submission and PHP files?

The concept of routing in PHP involves directing incoming requests to the appropriate PHP files based on the URL. This is commonly used in web applications to handle form submissions by routing the request to the PHP file responsible for processing the form data. By setting up routing rules, developers can organize their code and improve the overall structure of their application. 

<?php
// index.php
$route = $_SERVER['REQUEST_URI'];

switch ($route) {
    case '/form-submit':
        include 'form-submit.php';
        break;
    // Add more cases for other routes as needed
    default:
        echo '404 Not Found';
}
?>
