What are some best practices for using mod_rewrite and PHP to manage URL routing efficiently?

When using mod_rewrite and PHP to manage URL routing efficiently, it is important to create a clear and organized structure for your URLs. This can be achieved by defining specific rules in your .htaccess file using mod_rewrite to redirect incoming requests to the appropriate PHP script. In the PHP script, you can then parse the URL parameters and execute the corresponding logic based on the routing rules. 

// .htaccess
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [L]

// index.php
$url = $_GET['url'];
$routes = [
    'home' => 'home.php',
    'about' => 'about.php',
    'contact' => 'contact.php'
];

if(array_key_exists($url, $routes)) {
    include $routes[$url];
} else {
    include '404.php';
}
