Why is it recommended to use post-Requests instead of get-Requests for data-altering operations in PHP?

It is recommended to use post-Requests instead of get-Requests for data-altering operations in PHP because get-Requests expose the data in the URL, making it visible to users and potentially compromising sensitive information. 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 data for operations that alter the state of the system.

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Handle data-altering operations here
} else {
    // Redirect or display an error message for invalid requests
}
