PHP do not have js engine to run js code. And requesting data from your own server is quite nonsense — Your Common Sense

You're trying to retrieve information from a file on your server and then displaying that returned information on the page - using JavaScript? — jlindenbaum

no, not the returned information, but the url page...or the xmlhttprequest or whatever it is.. it is something like localhost/jquerystudy/mine/processjson.php?path=masterData/…} — jayAnn

PHP is server side while Javascript is client side. The only way to get you parameters to js would be to return them via an array in an ajax call (ie. return as json) or echo the parameters to the final page where the js will hold them.

echo the parameters to the final page?... i already tried that one but the output is in complete. it will not display "localhost....". instead, it will only display the "processjson.php?path=masterData/...."

something like: echo "<script>var url = '$url';</script>"; where $url is the php version of the url. Then you can access it in your js using the url variable.

Because the file_get_contents function is processed on the server side before sending the response, there is no way for javascript to access the value of the argument. You could, however, use PHP to write additional HTML (or javascript) that's sent in the response; something like this:

  <?php
        echo "<script>var url='http://localhost/" . $_GET["path"] . "?json=" . urlencode($_GET["json"])."';</script>";
    ?>

You'd then have a javascript variable with that argument.
