I'm new to php, but can anyone give me the proper syntax to initialize a javascript variable with a php variable value?

What is in your javascript that you need? What variable? How is it being passed, what was it from originally?

If you can answer these I can probably give you the best way to do this.

Hmm, I'm not sure about proper syntax, but here's the way I do it (and the way I do it in ASP).

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

This may not be the proper way, but it works for me.

HTH!

That's the ASP way. In PHP, like ASP, you can print any variables to output, including HTML output, including inside a Javascript tag like this:

<?PHP
print "<script language=\"Javascript1.2\">\nfoo=$foo;\n</script>";
?>

(results at http://www.peakepro....h/foo.php?foo=3 )

or this:

<script language="Javascript1.2">
foo=<?PHP print $foo; ?>;
</script>

(results at http://www.peakepro..../foo2.php?foo=3 )

Either will work. Be wary of mixing HTML and PHP in large applications; it can create maintenance headaches.

<?php print $foo; ?> == <?=$foo?>

in more recent versions of PHP...

As will the method I described. I'll agree with cyberscribe's caveat concerning the mixing of both, however. It can get nasty to debug on large apps.

Yikes! PHP is turning into Perl.

Couldn't find the versioning, but found this along the way which is worth noting:
