    How to get the value of the HTML title tag?

    I was using the below javasciprt code, can the innerHTML be used in PHP? Is it possible to change this code into php?
    Code:
    function get_title() {
	var t = document.getElementsByTagName('title')[0];
	if ( !!t.childNodes.length ) {
		document.write(t.firstChild.data);
	} else if ( t.innerHTML ) {
		document.write(t.innerHTML);
	}
}

      You can output any type of code that will go into the HTML page using PHP.

      Are you trying to get a new page title from the server based on some "on server" processing? If YES, you can make it easier by having a variable defined in JavaScript; I'd suggest an anonymous object or out of GLOBAL scope, and make an AJAX call on a PHP script at the server.

      Generating "in page" JavaScript is done all the time.

      Although after the code generation is done, there is no longer a connection to the PHP script running on the server. YOU can get very sophisticated and replace JavaScript script tag contents on the fly; even via AJAX calls to a PHP script - as mentioned above.

      Code:
      <html>
  <head>
    <title><?php echo $page_title?></title>
    <script type="text/javascript" src="<?php echo getScript()?>"></script>
    <script type="text/javascript">
      <?php
        // Generate a bunch of JavaScript code here...
      ?>
    </script>
  </head>
  <body>

  </body>
</html>

          Sorry for the confusing post... I was very sleep deprived...

          A specific line from the original post should be read as:
          "I'd suggest an anonymous object or an out of GLOBAL scope variable"
