(PHP 5 >= 5.2.1)

stream_socket_shutdownShutdown a full-duplex connection

Description

bool stream_socket_shutdown ( resource $stream , int $how )

Shutdowns (partially or not) a full-duplex connection.

Parameters

stream

An open stream (opened with stream_socket_client(), for example)

how

One of the following constants: STREAM_SHUT_RD (disable further receptions), STREAM_SHUT_WR (disable further transmissions) or STREAM_SHUT_RDWR (disable further receptions and transmissions).

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 A stream_socket_shutdown() example

<?php

$server 
stream_socket_server('tcp://127.0.0.1:1337');
$client stream_socket_client('tcp://127.0.0.1:1337');

var_dump(fputs($client"hello"));

stream_socket_shutdown($clientSTREAM_SHUT_WR);
var_dump(fputs($client"hello")); // doesn't work now

?>

The above example will output something similar to:

int(5)

Just a note to say that if you encounter problem closing some sockets using fclose in a multi client server, you should really  give this one a try.

Spent a full day trying to resolve this issue using stream_socket_shutdown($clientStream,STREAM_SHUT_RDWR);
finally do the trick.

Be wary of using stream_socket_shutdown with a TLS socket. The socket is closed without sending the "close_notify" message required by TLS protocol.

To correctly close a TLS socket, use fclose() instead, which internally calls OpenSSL's SSL_shutdown() function.

As Daniel J has pointed out, stream_socket_shutdown doesn't send the TLS close_notify message. In some instances, it's a preferred function over fclose (to trigger stream_select, for example).

To use this function correctly with TLS, use stream_socket_enable_crypto($fp, false); before shutting down the socket.
