Why is it recommended to use POST requests instead of GET requests for operations that modify data in PHP applications?

Using POST requests instead of GET requests for operations that modify data in PHP applications is recommended because GET requests append data to the URL, making it visible and potentially accessible to others. POST requests, on the other hand, send data in the request body, keeping it hidden from users and providing a more secure way to transmit sensitive information.

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process the form data here
}
