Hi there,

I've never used PHP before, but if it's like ASP, you should be able to do this...

(Sorry if this doesn't work!!!)

 <?php
  $number=rand();
 
 ?>
 
 For JavaScript:
 <Script>
  var num = "<?=$number?>";
 
 </script>

The quotes just make sure that there isn't a syntax error if $number contains nothing (in this case it should always have something, but not for all instances is $number guaranteed to have anything).

Unfortunately following does not work.

<?php
	$number = rand();
?>

<script language="javascript">
	var num = <?php $number ?>
	document.write(num)
</script>

It says "undefined".

Then this suggests two possibilities.

1. PHP does not allow $number to be accessible across data islands (which to me sounds almost impossible)

2. The value returned from rand() when assigned to $number is undefined.

Either way, this is starting to sound like a problem with PHP rather than JavaScript q:)

It's definately possible with Perl and ASP, so I can't see why it wouldn't work!

You'll just need to place the echo command in between:

var num=<? echo $number; ?>;
