Ignore all the PHP hate. It is clearly the best language.
- Very easy to learn (Compare with Perl, it will take you years just to learn the syntax)
- Friendly user community with experts eager to help (compare with Perl, full of incompetent assholes, and Ruby, full of immature dicks).
- The best documentation for any language. Just type
http://php.net/name_of_whatever_function and you get the documentation, right now, no effort (compare with Ruby... oh wait you can't, they have no documentation at all).
- Share-nothing architecture engineered to deliver perfect horizontal scalability. (I don't even have to name names here)
- Cpan is full of jokes packages (they have a whole NAMESPACE dedicated to those) and software that stayed at version 0.0.1 for years. When you use a PEAR module, you get the assurance that it's robust and actively maintained. Don't look at the numbers, look at the facts.
