Update ExtJS Progressbar with php

Hi,

I have a loop in a PHP script and i would like to update a ExtJs progressbar ?

Is it possible to do that (and how) ?

Thanks

You are probably looking for a server-push functionality such as comet or reverse ajax, which Ext does not (yet) support natively. There are a few proof of concept code examples floating around if you search, but its a pretty advanced topic.
