Creates a stream or datagram socket on the specified local_socket
.
This function only creates a socket, to begin accepting connections use stream_socket_accept().
The type of socket created is determined by the transport specified using standard URL formatting: transport://target.
For Internet Domain sockets (AF_INET
) such as TCP and UDP, the target portion of the remote_socket
parameter should consist of a hostname or IP address followed by a colon and a port number. For Unix domain sockets, the target portion should point to the socket file on the filesystem.
Depending on the environment, Unix domain sockets may not be available. A list of available transports can be retrieved using stream_get_transports(). See List of Supported Socket Transports for a list of bulitin transports.
If the optional errno
and errstr
arguments are present they will be set to indicate the actual system level error that occurred in the system-level socket(), bind(), and listen() calls. If the value returned in errno
is 0 and the function returned FALSE
, it is an indication that the error occurred before the bind() call. This is most likely due to a problem initializing the socket. Note that the errno
and errstr
arguments will always be passed by reference.
See errno
description.
A bitmask field which may be set to any combination of socket creation flags.
Note:
For UDP sockets, you must use
STREAM_SERVER_BIND
as theflags
parameter.

Returns the created stream, or FALSE
on error.
<?php $socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr); if (!$socket) { echo "$errstr ($errno)<br />\n"; } else { while ($conn = stream_socket_accept($socket)) { fwrite($conn, 'The local time is ' . date('n/j/Y g:i a') . "\n"); fclose($conn); } fclose($socket); } ?>
The example below shows how to act as a time server which can respond to time queries as shown in an example on stream_socket_client().
Note: Most systems require root access to create a server socket on a port below 1024.
<?php $socket = stream_socket_server("udp://127.0.0.1:1113", $errno, $errstr, STREAM_SERVER_BIND); if (!$socket) { die("$errstr ($errno)"); } do { $pkt = stream_socket_recvfrom($socket, 1, 0, $peer); echo "$peer\n"; stream_socket_sendto($socket, date("D M j H:i:s Y\r\n"), 0, $peer); } while ($pkt !== false); ?>
