How can PHP be used to manipulate hidden fields created dynamically by JavaScript?

When hidden fields are created dynamically by JavaScript, they may not be directly accessible by PHP when the form is submitted. To manipulate these hidden fields using PHP, you can store their values in session variables or pass them as parameters in the form submission. This way, PHP can access and manipulate the hidden field values. 

<?php
session_start();

if(isset($_POST['hidden_field'])) {
    // Manipulate the hidden field value
    $hiddenFieldValue = $_POST['hidden_field'];
    
    // Example manipulation: appending 'PHP' to the hidden field value
    $manipulatedValue = $hiddenFieldValue . 'PHP';
    
    // Output the manipulated value
    echo $manipulatedValue;
}

?>
