You have to call read/recv or write/send before you call last_error. You should get FALSE from the return of your read/recv, and socket_last_error should contain EAGAIN if no data is avail on a non-blocking socket, ECONRESET if the connection was reset by the peer(etc..etc..), or you would get "" from the return of the read (0 bytes from recv) which would indicate EOF. -Jason > > -- > PHP Development Mailing List <http://www.php.net/> > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
