Note Submitter: fphilibert@realink.org ---- Please, note that the returned value for the current working directory under Win32 is like "c:\directory_name". In order to write a user function that works unmodified both on Un*x and on Win32 platforms, you have to replace the "\" with "/", and to strip the volume letter (provided the accessed directory is on the same drive than the webserver. On Un*x platforms, the function getcwd(); returns a result similar to exec("pwd");.
