Are there any best practices for handling form data and button clicks in PHP scripts?

When handling form data and button clicks in PHP scripts, it is best practice to check if the form has been submitted before processing the data. This can be done by checking if the request method is POST and if the submit button has been clicked. By following this approach, you can ensure that the form data is only processed when the form is actually submitted. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["submit"])) {
    // Process form data here
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Perform validation and other operations
}
?>
