PRADO is the php equivolent to save asp.net. I think that it has some potential for specific developers, especially as a gui gets built to harness the ease of use that type of approach gives developers. But the overhead for going back to the server for each action is something I rarely see as a good thing unless you are doing intranet sites. There are ways to optimize as in asp.net with disabling viewstate but in the long run I see most scripting languages going this way.
