socket_accept

Accepts a connection on a socket (PHP 4 >= 4.0.7, PHP 5)
resource socket_accept ( resource socket )

After the socket socket has been created using socket_create(), bound to a name with socket_bind(), and told to listen for connections with socket_listen(), this function will accept incoming connections on that socket. Once a successful connection is made, a new socket resource is returned, which may be used for communication. If there are multiple connections queued on the socket, the first will be used. If there are no pending connections, socket_accept() will block until a connection becomes present. If socket has been made non-blocking using socket_set_blocking() or socket_set_nonblock(), FALSE will be returned.

The socket resource returned by socket_accept() may not be used to accept new connections. The original listening socket socket, however, remains open and may be reused.

Parameters

socket: A valid socket resource created with socket_create().

Return Values

Returns a new socket resource on success, or FALSE on error. The actual error code can be retrieved by calling socket_last_error(). This error code may be passed to socket_strerror() to get a textual explanation of the error.

socket_accept with timeout, seems to work for me on Apache/1.3.37 (FreeBSD 6.0) PHP/4.4.7. Adapted from ScriptBlue at nyc dot rr dot com's post under socket_connect. <?php $socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); socket_bind($socket,$address,$port); socket_listen($socket); echo "Waiting for a connection\n"; $conn = false; switch(@socket_select($r = array($socket), $w = array($socket), $e = array($socket), 60)) { case 2: echo "Connection refused\n"; break; case 1: echo "Connection accepted\n"; $conn = @socket_accept($socket); break; case 0: echo "Connection timed out\n"; break; } if ($conn !== false) { // communicate over $conn } ?>

This example doesn't work. You have to call socket_listen($fd) after your bind in order to accept incoming connections. Simon
