how to let php reflesh part of page

[scorpioy]

I want to write some code that when some variable condition is met, it will change a table cell value (only reflesh that value instead of the whole page), I used to think it as calling JavaScript function first, which in turn change that table cell value in the page. But I don't know how to let php call JavaScript, or mimic click button action to call JavaScript.

Can someone help me on this? Thanks.

You've got to use AJAX

Or iframe...

I have some basic knowledge about AJAX. But isn't it still having JavaScript involved. Then When my php script is trigered by something, how do I make php call JavaScript which in turn does AJAX?

Please help.
