Thanks a lot forr your reply.
Here is the error msg:
*Warning*: fopen(/dev/pmsg)
[function.fopen<http://localhost/Source/test/function.fopen>]:
failed to open stream: Permission denied in *
/var/www/html/Source/test/register_user.php* on line *31
It still doesn't work even if I move pmsg to /tmp/ directory and change its
own to appache...
