In the php.ini the include_path for windows systems looks something like this:
; UNIX: "/path1:/path2"
;include_path = ".:/php/includes"
;
; Windows: "\path1;\path2"
include_path=".;C:\php\PEAR"
I understand the paths themselves, but what does the ".:" mean in the Unix include path, and the ".;" mean in the Windows include path?
