This code
return $this->var1 .DS. $this->var2;
won't work on Windows (XP) while it does on Mac OS. ('DS' is defined as DIRECTORY_SEPARATOR.)
If I change the code, that is change DS with "/",
return $this->var1 ."/". $this->var2;
then it works.
Why doesn't it work (or where am I mistaking)? Would really like to use DS in place of "/".
