What is the purpose of passing values from HTML to PHP in this code snippet?

Passing values from HTML to PHP allows you to collect user input or data from a form on a webpage and process it using server-side scripting with PHP. This enables you to perform various operations on the data, such as saving it to a database, sending emails, or generating dynamic content based on user input. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $email = $_POST['email'];
    
    // Process the data as needed, such as saving it to a database or sending an email
    
    // Redirect to a thank you page or display a success message
    header("Location: thank_you.php");
    exit();
}
?>
