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.

Sockets should be first shutdown and then closed.

<?php

// Sample: Closing sockets gracefully

socket_shutdown($sock, 2);

socket_close($sock);

?>
