What is the recommended alternative to using $_REQUEST in PHP?

Using $_REQUEST in PHP is not recommended due to security concerns as it combines data from GET, POST, and COOKIE requests, making it vulnerable to injection attacks. It's better to use $_GET or $_POST specifically, depending on the type of request being made. This ensures that you are only accessing the data from the intended source and reduces the risk of security vulnerabilities. 

// Example of using $_POST instead of $_REQUEST
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    // Process the form data securely
}
