In PHP, why is it recommended to always use POST requests for actions that modify data in a database instead of GET requests?

When modifying data in a database, it is recommended to use POST requests instead of GET requests because GET requests expose 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, which is not visible in the URL. This helps improve security and protects sensitive data from being exposed. 

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process the form data and modify the database here
} else {
    // Redirect or display an error message for invalid requests
}
