How can PHP be used to dynamically load iframes and save their positions in the DOM using cookies?

To dynamically load iframes and save their positions in the DOM using cookies, you can use PHP to generate the iframe elements with unique IDs and then use JavaScript to save and retrieve their positions in cookies. This way, when the page is reloaded, the iframes will be loaded in their previous positions. 

<?php
// PHP code to generate iframes with unique IDs
for ($i = 1; $i <= 3; $i++) {
    echo '<iframe id="iframe'.$i.'" src="iframe'.$i.'.html"></iframe>';
}
?>

<script>
// JavaScript code to save and retrieve iframe positions in cookies
window.onload = function() {
    var iframes = document.getElementsByTagName('iframe');
    
    for (var i = 0; i < iframes.length; i++) {
        var iframe = iframes[i];
        var iframeId = iframe.id;
        var iframePosition = localStorage.getItem(iframeId);
        
        if (iframePosition) {
            iframe.style.left = iframePosition.split(',')[0];
            iframe.style.top = iframePosition.split(',')[1];
        }
        
        iframe.addEventListener('mouseup', function() {
            var position = this.style.left + ',' + this.style.top;
            localStorage.setItem(this.id, position);
        });
    }
}
</script>
