Isn't this / ?

Why is there a constant for it? It's not like it can change, right?

PATH_SEPARATOR is the character used to separate many paths in a unique string (like include_path in php.ini).

Its value is ':' on a UNIX system and ';' on a Windows system.

What you're talking about ('/' on UNIX and '' on Windows) is the DIRECTORY_SEPARATOR constant.
