:: in PHP

[Decode]

I was wondering what "::" is used for, I saw it in Jewish Bears signature. It was like $var = hi :: function().

Thanks

It's the scope resolution operator, it's similar to -> only you don't need to do $blah = new blah(); you just do include('file.php'); then className::functionName();

It allows access to static, constant and over-ridden members / methods of a class.
