PHP and JS question when is php code called?

[That's what she said]

Hey...Question about JS functions.

So If I have a .php file which has a few javascript functions in it...is the php code that is INSIDE the js function only called when the JS function is called?

so lets say within the js code I have say <?php echo total();?> //PHP FUNCTION

will that be called when ever the document is run, or jsut when the JS function is called?

Thanks!

It will only be called once, when the document is requested.
