What is the purpose of using a PHP script to dynamically resize an iframe?

When embedding an iframe on a webpage, the size of the iframe is typically fixed. However, in some cases, you may want the iframe to dynamically resize based on its content. One way to achieve this is by using a PHP script to calculate the height of the content within the iframe and adjust the iframe height accordingly. 

<?php
// Get the height of the content inside the iframe
$content_height = // Calculate the height of the content dynamically

// Set the new height of the iframe
$new_height = $content_height + 20; // Add some extra padding
echo "<script type='text/javascript'>
        parent.document.getElementById('iframe_id').style.height = '$new_height' + 'px';
      </script>";
?>
