What are best practices for handling different request methods in PHP?

When handling different request methods in PHP, it is best practice to use the $_SERVER['REQUEST_METHOD'] variable to determine the method used for the current request. This allows you to properly handle GET, POST, PUT, DELETE, etc. requests in your PHP script. 

// Check the request method
$request_method = $_SERVER['REQUEST_METHOD'];

// Handle different request methods
if ($request_method === 'GET') {
    // Handle GET request
} elseif ($request_method === 'POST') {
    // Handle POST request
} elseif ($request_method === 'PUT') {
    // Handle PUT request
} elseif ($request_method === 'DELETE') {
    // Handle DELETE request
} else {
    // Handle unsupported request method
}
