What are the limitations of directly controlling iframes from PHP and how can JavaScript be used as a workaround for reloading content dynamically?

When using PHP to directly control iframes, there are limitations in dynamically reloading content within the iframe without refreshing the entire page. To work around this limitation, JavaScript can be utilized to dynamically reload the content within the iframe without affecting the rest of the page. 

<!-- PHP code to generate iframe with dynamic content reload using JavaScript -->
<iframe id="myFrame" src="initial_content.php"></iframe>
<button onclick="reloadIframe()">Reload Content</button>

<script>
function reloadIframe() {
  var iframe = document.getElementById('myFrame');
  iframe.src = iframe.src; // Reloads the iframe content without refreshing the entire page
}
</script>
