What is the significance of using $_POST instead of $_REQUEST in PHP forms?

Using $_POST instead of $_REQUEST in PHP forms is significant for security reasons. $_POST only retrieves data sent via the POST method, which is more secure than using $_REQUEST, which can also retrieve data sent via GET and COOKIE methods. By using $_POST, you can prevent potential security vulnerabilities such as CSRF attacks. 

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