Anyone has any method he/she uses to accomplish this?

The scenario is I have a php document containing some variables and I need to do some calculations in a seperate javascript file using those php variables. I have already achieved this but I am trying to optimize my codes so i'm looking to know if there's a better way anyone has of doing this.

Here's how I do it.
I use html as the bridge. I include the php document into html and pass the variables into hidden form fields
<input type="hidden" value ="<?php echo $variable1 ?>" id = "variable1" />

In javascript I now get the variable from the hidden field in the html.
var variable1 = parseInt($('#variable1').val());

And then I can do any math I want.

Now imagine crossing about a hundred variables from php to javascript through my kinda bridge! That's too many kids on the bridge!! I know there must be a better way, any ideas?

<script language="javascript">var e='<?php echo $variable;?>';</script>

Hmmm,

Another way I can think of is masking ur php as js and passing the variables to it via GET like this

HTML:
<script type="text/javascript" src="js/js.php?var=value&var2=value2"></script>

JS (js.php):
<?php
header('content-type:application/x-javascript');
foreach($_GET as $k => $v){
  $$k = $v;
}
?>
var variable1 = <?= $var; ?>;
var variable2 = <?= $var2; ?>;

The drawback however, is that it is assumed the variables are already declared before including the js.

I think you can pull some resources from here

www.phpjs.org

I know it will be of great help.

Thanks guys
