PHP
-no multi-threading (VFP can do this fairly smoothly)
-no ISAPI on Windows (VFP web tools use ISAPI all over the place, so PHP performance will suffer and, no, FastCGI is not nearly as good))
-no 64 bit on Windows (VFP can't either but this is mainly for data anyway)
-no intermediate byte code (like JIT in .NET) or automatic Garbage collection (VFP check, check)
-of course, no integrated database
-language is harder to learn than VFP imo
-not a great COM story (VFP has an excellent COM story, of course)

IMHO, PHP is one of those "good enough" languages that caught on with enough good, young programmers, primarily on LINUX to generate a lot of great applications primarily on LINUX that got ported over to Windows as an afterthought.

I'm a fan of PHP but don't delude yourself that it works better than VFP on Windows, even for web apps.

>>>FWIW, I switched to PHP a little lest than two years ago. Frankly, for doing web stuff, I like PHP better then VFP. The hard part is going back and forth.

>Some years back I posted in a thread comparing PHP to C# to conduct a typical web function. As always some saw this as a p*ssing contest, but my intent was to show that PHP is very readable for VFP'ers. Easy enough to make the switch, and it'll keep getting easier. I still don't "get" technical reasons why some people are so opposed- but then I had the same thoughts about Remote Views and change tracking. ;-)
