How can JavaScript be utilized to retrieve the content of a frame for PHP processing?

To retrieve the content of a frame for PHP processing using JavaScript, you can use the `contentWindow` property of the frame element to access its content document. You can then use the `innerHTML` property to retrieve the HTML content of the frame. 

<?php
  // Retrieve the HTML content of the frame using JavaScript
  $frame_content = "<script>
                      var frame = document.getElementById('frame_id');
                      var frame_content = frame.contentWindow.document.documentElement.innerHTML;
                      console.log(frame_content);
                    </script>";
  
  // Process the retrieved content in PHP
  // For example, you can echo the content
  echo $frame_content;
?>
