javascript and PHP

Ok. My last post didn't go throught the list software because of the tags. I am replacing the "<" and ">"'s with *'s now so that hopefully it will go through so that people can see it. ------Original message---- Does anybody know of a good/short tutorial about passing variables from JavaScript to/from PHP? For example, how to do the following: *html* *head* *SCRIPT LANGUAGE="JavaScript"* $data = "hello world"; */script* */head* *body* *? echo "$data*br*"; ?* */body* */html* The above might at least give me a clue. Just a note. I really know nothing to speak of about JavaScript. Thanks in Advance Steve
