What are the differences between using $_POST and $_REQUEST when handling form data in PHP?

When handling form data in PHP, it is generally recommended to use $_POST over $_REQUEST for security reasons. $_POST only contains data submitted through the POST method, while $_REQUEST includes data from both GET and POST requests. By using $_POST, you can ensure that you are only accessing data that was meant to be submitted securely. 

// Using $_POST to handle form data in PHP
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Process the form data securely
}
