Why is it recommended to use $_POST instead of $_REQUEST in PHP code for form submissions?

It is recommended to use $_POST instead of $_REQUEST in PHP code for form submissions because $_POST only retrieves data sent via the POST method, which is more secure and prevents unintended data manipulation. Using $_REQUEST can potentially expose your application to security vulnerabilities if data is sent via the GET method. By explicitly using $_POST, you ensure that your form submissions are handled securely. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data securely using $_POST
}
