If your script is inline on a PHP page:

myChart.setDataURL("<?php echo $mytempname; ?>");

Even if it's not, you would use the same syntax, but let's say your script is called chart.js and you use a tag like:

<script type="text/javascript" src="chart.js"></script>

to get it onto your page. Then you need to rename it to chart.php and call it like so to your page:

<script type="text/javascript" src="chart.php"></script>

AND you need to put this as the very first line in it:

<?php header('Content-type: text/javascript'); ?>
