Help please: Passing PHP values to Javascript

Hi,

I need to pass some PHP values to Javascript. I tried the following example:

<? $vartopass = "Hello"; ?>
<script = "javascript">
var strnewVar = '<?=$vartopass?>';
alert(strnewVar);
</script>

But the screen output is "<?=$vartopass?>" instead of "Hello".
What's wrong with my code? How to make it work?

Thanks a lot for any help.

 

Perhaps you don't have PHP short tags on (I'm assuming this is in a PHP script.)

Try:
<?php echo $vartopass; ?>

 

Thank you Danltn for the reply.
I tried your code, but the alert didn't show at all this time. Do you know what the reason probably is?

Thank you very much.

 

Is the file extension .php?

<script = "javascript">
var strnewVar = '<?=$vartopass?>';
alert(strnewVar);
</script>

Should be...
<script type="text/javascript">
...
</script>
