How can the use of iframes impact the functionality of TinyMCE in a PHP environment?

When using iframes within TinyMCE in a PHP environment, it can sometimes cause issues with the editor's functionality, such as content not being displayed correctly or saved properly. One way to solve this issue is to disable the automatic cleanup of iframes in TinyMCE by setting the `cleanup` option to `false` in the configuration. This allows the iframes to be preserved without interference from TinyMCE's cleanup process. 

// Initialize TinyMCE editor with iframe cleanup disabled
<script>
  tinymce.init({
    selector: 'textarea',
    cleanup: false
  });
</script>
