What are common issues with caching in PHP when using iframes or divs in Internet Explorer?

Common issues with caching in PHP when using iframes or divs in Internet Explorer can arise when the browser does not properly refresh the content within the iframe or div, leading to outdated or cached content being displayed. To solve this issue, you can add a random query string parameter to the URL of the iframe or div content, forcing the browser to fetch the content anew each time. 

<div>
    <iframe src="content.php?<?php echo uniqid(); ?>"></iframe>
</div>
