What are some alternative methods to dynamically resize iframes in PHP scripts that are more universally compatible?

When dynamically resizing iframes in PHP scripts, it's important to consider cross-browser compatibility and ensure the resizing works consistently across different platforms. One alternative method is to use JavaScript to dynamically adjust the height of the iframe based on its content, as this approach is more universally compatible.

<?php
echo '<iframe id="myIframe" src="https://example.com"></iframe>';
echo '<script>
    var iframe = document.getElementById("myIframe");
    function resizeIframe() {
        iframe.style.height = iframe.contentWindow.document.body.scrollHeight + "px";
    }
    iframe.onload = resizeIframe;
</script>';
?>
