[cmm14513]

php means personal home page,
it is used for webprogramming,
it is compiled and executed by the apachee server,
it is independent in both windows and linux operating system.

Actually, PHP means PHP HyperText Preprocessor, and has been called that for a while now...

It's a scripting language, not a programming language.

The only "event" PHP really know is the start event, when a page containing PHP code is opened.
