What resources or tutorials would you recommend for someone looking to refresh their knowledge of PHP form handling and variable usage?

To refresh your knowledge of PHP form handling and variable usage, I recommend checking out online tutorials on websites like W3Schools, PHP.net, and TutorialsPoint. These resources offer comprehensive guides and examples on how to properly handle form submissions, validate user input, and work with variables in PHP. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process form data or perform validation here
}
?>
