How can hidden input fields be utilized to pass variables between PHP scripts?

Hidden input fields can be utilized to pass variables between PHP scripts by including them within a form that is submitted to another PHP script. These hidden input fields can store data that needs to be transferred between scripts without displaying it to the user. The receiving PHP script can then access this data using the $_POST or $_GET superglobals. 

// Sending PHP script
<form action="receiver.php" method="post">
    <input type="hidden" name="variable_name" value="variable_value">
    <input type="submit" value="Submit">
</form>

// Receiving PHP script (receiver.php)
<?php
$received_variable = $_POST['variable_name'];
echo $received_variable;
?>
