this function, compared to the function socket_accept, got an extra argument "timeout".
To make this function wait indefinitelly to incoming connections, just as in socket_accept, set timeout to -1. It works for me with PHP 5.0.4.
stream_socket_accept
Description
resource stream_socket_accept ( resource server_socket [, float timeout [, string &peername]] )Accept a connection on a socket previously created by stream_socket_server(). If timeout is specified, the default socket accept timeout will be overridden with the time specified in seconds. The name (address) of the client which connected will be passed back in peername if included and available from the selected transport.
peername can also be determined later using stream_socket_get_name().
If the call fails, it will return FALSE.
| 警告 |
This function should not be used with UDP server sockets. Instead, use stream_socket_recvfrom() and stream_socket_sendto(). |
See also stream_socket_server(), stream_socket_get_name(), stream_set_blocking(), stream_set_timeout(), fgets(), fgetss(), fwrite(), fclose(), feof(), and the Curl extension.

This code could be very helpfull...
The following code is for the "server". It listen for a message until CTRL-C
<?php
while (true)
{
// disconnected every 5 seconds...
receive_message('127.0.0.1','85',5);
}
function receive_message($ipServer,$portNumber,$nbSecondsIdle)
{
// creating the socket...
$socket = stream_socket_server('tcp://'.$ipServer.':'.$portNumber, $errno, $errstr);
if (!$socket)
{
echo "$errstr ($errno)<br />\n";
}
else
{
// while there is connection, i'll receive it... if I didn't receive a message within $nbSecondsIdle seconds, the following function will stop.
while ($conn = @stream_socket_accept($socket,$nbSecondsIdle))
{
$message= fread($conn, 1024);
echo 'I have received that : '.$message;
fputs ($conn, "OK\n");
fclose ($conn);
}
fclose($socket);
}
}
?>
The following code is for the "client". It send a message, and read the respons...
<?php
send_message('127.0.0.1','85','Message to send...');
function send_message($ipServer,$portServer,$message)
{
$fp = stream_socket_client("tcp://$ipServer:$portServer", $errno, $errstr);
if (!$fp)
{
echo "ERREUR : $errno - $errstr<br />\n";
}
else
{
fwrite($fp,"$message\n");
$response = fread($fp, 4);
if ($response != "OK\n")
{echo 'The command couldn\'t be executed...\ncause :'.$response;}
else
{echo 'Execution successfull...';}
fclose($fp);
}
}
?>
