What is the main issue the user is facing with their PHP script regarding dynamic page length adjustment?

The main issue the user is facing with their PHP script regarding dynamic page length adjustment is that the script is not properly adjusting the page length based on the content being displayed. To solve this issue, the user can calculate the height of the content and dynamically adjust the page length accordingly using JavaScript.

<?php
echo "<html>
<head>
<script>
window.onload = function() {
    var contentHeight = document.getElementById('content').clientHeight;
    window.resizeTo(800, contentHeight + 100); // Adjust the width as needed
}
</script>
</head>
<body>
<div id='content'>
// Your dynamic content here
</div>
</body>
</html>";
?>
