Sorry, you are out of luck.
JavaScript is on the client side, PHP is on the server side. You will need to write a JavaScript function to emulate whatever the php function does.

If you absolutely need to get Javascript to trigger something in PHP, you have a few options, none of which are pretty:

- open a popup window (could be blocked, you could make it visible, or make it very very small)
- open a pop-under window (virtually invisible but could be blocked)
- use a hidden frame

any of these sound good?  if not, just make a new request to the server, do whatever you need to do, and bring the user back to the page she was on.   if you need to maintain some variables you can just pass them along in PHP...

hope that helps.

Well the simplest thing to do would first:
input type="text" name="world" onchange="javascript:world()"

and create a spot on your page -preferably a text box as to keep things simple.
<input type="textbox" name="datadisplay" value="">

second:
insert this at the top of your page
<script language="javascript">
function world(){
  document.datadisplay.value="Hello world!"
}

This should get your desired affect - if you have a better example of what you are trying to do, it would help to better illustrate what you need and point to some preexisting javascript code that you could use.

Hope this helps,
