why not use a script include instead of a php one?  ie:

You don't and you can't. PHP does not interact with the client (like you are 
thinking it does) and Javascript does not interact with the server. They are 
completely different and not related, except that PHP can send Javascript to 
the client for the client to interpret.

It's a bit confusing at first but once you understand it, you'll wonder why it 
ever didn't make sense.

You can't do that.

You could do this:


Then, when the page gets sent to the browser, the def() function gets
called by the browser.

PHP runs on your server.

JavaScript is run by the browser, on the web surfer's computer, millions
of miles away, and long after PHP has finished its work and gone away.

Now... i want to call this JavaScript function from the regular PHP
files. In particular, before the HTML code.
Like this:

How can i do this ?
How to tell PHP, that def(word) is a JS function in js.php file ?
I've tried include ('js.php'), etc., but got no results :(
include ('js.php') will output the contents of that file to the browser,
assuming include() actually finds the file.

You don't and you can't. PHP does not interact with the client (like you are thinking it does) and 
Javascript does not interact with the server. They are completely different and not related, except 
that PHP can send Javascript to the client for the client to interpret.
javascript is a scripting language, there is no theoretical reason that it 
can't be used as a serverside
scripting language, but the fact that practically nobody in the real does says 
something :-). anyway
its not strictly correct to say javascript is 'clientside'.
as for calling a javascript function directly from php code, forget about it.
It's a bit confusing at first but once you understand it, you'll wonder why it ever didn't make sense.
1 round trip:
1. a (php) webserver gets a request for a page.
2. the server runs the requested (php) script.
3. the server sending some output to the browser.
4. the browser interprets the output.
the output is generally a webpage - this can include
