symbols

Some time ago I had a look into Ruby and one of the things which stood out most for me was the way of using symbols.

While you to use defines or strings like in C++ or Python as an alternative, in Ruby you just write :mySymbol and the interpreter takes over the enumeration for you.

I can't see any disadvantage this feature has, so why is it missing in say, PHP and Python?
