"Superior" is good commentary. No way you can quantify that. But, as I have never used PHP and don't have plans to do so, I won't say anything else on PHP vs. VFP.

>Gee, how about good old foxpro with jQuery and jQuery Mobile (this is a foxpro forum after all...), especially if you have a bunch of existing vfp code and experience. VFP is superior to PHP on windows. It just doesn't have as many free and cheap web apps available.
