It's worth repeating:

VFP is better than PHP because:
VFP uses ISAPI (PHP uses FASTCGI and discourages ISAPI for stability reasons)
VFP can truly multi-thread using a VFP MTDLL and can spawn a background thread (PHP cannot. PERIOD)
VFP has had memory garbage collection for quite some time (I believe this is a fairly recent addition to PHP)
VFP compiles to intermediate bytecode (PHP DOES NOT!)
VFP has a built-in and integrated database. PHP does NOT!
VFP is almost guaranteed to work better on Windows because of Microsoft's long involvement with it

If you've got existing VFP code and experience and your customers are not demanding that you use something different because of "something they heard about foxpro", it's pretty much a no-brainer if you want to save money and time.

>"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.
