Why did you choose PHP?

PHP for life

Well, I was thinking about: why do I use PHP? I met the language after I have learned a little of Perl, and as soon I saw it I loved it. In few time, I was noting that it is more fantastic then I though. It did "magic" for programmers. I select some features:

  • Magic methods and some interfaces to overload core language actions;
