That is not a good example of a graceful shutdown. One should close the sending side of the socket and continue to read until the remote end closes its sending connection.

ludvig dot ericson

Sockets should be first shutdown and then closed. <?php // Sample: Closing sockets gracefully socket_shutdown($sock, 2); socket_close($sock); ?>
