yes that makes sense. But i wonder, does that imply python or ruby are more difficult to understand than php? I believe they must be on the same level of sophistication and understandability.
And if python, (or ruby) for example, was "better" (as in gets more developer love) then shouldn't it's availability on hosting services increase? Its not like either of php or python is new and needs time to settle down. If availability on hosting providers were to increase, it would have increased long ago.
and as for file extensions, as i noted in another comment in this thread, file extension is just a part of my observation. It also includes tutorials, how-tos, questions/answers on stack overflow-like sites, etc. all of these are more for php than any other language.
