How can the use of JavaScript SRC attribute be optimized for embedding PHP scripts on various web pages?

When embedding PHP scripts on various web pages using the JavaScript SRC attribute, it is important to dynamically generate the URL of the PHP script to ensure it works correctly on different pages. This can be achieved by using PHP to echo out the URL of the PHP script within the JavaScript code. 

<script>
  var phpScriptUrl = "<?php echo 'http://www.example.com/script.php'; ?>";
  var script = document.createElement('script');
  script.src = phpScriptUrl;
  document.body.appendChild(script);
</script>
