Re: Calling Javascript-function from php-script ...

I think the point here is that it be made clear to those who might get confused that the javascript (unless it's a server-side script) is running in a browser and as such there is no way for the server to 'make a call to it by URL.' The Javascript can call the server but the server-side PHP script cannot call the client. Therefore, no PHP script can 'call' a javascript function.
