The socket returned by this resource will be non-blocking, regardless of what the listening socket is set to. This is actually true for all FCNTL modifiers.

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 } ?>

Be aware signal handler functions set with pcntl_signal are not called while a socket is blocking waiting for a connection; the signal is absorbed silently and the handler called when a connection is made.

Accepting a connection using php-sockets: $fd = socket_create(AF_INET, SOCK_STREAM, 6 /* OR getprotobyname("TCP")*/); $PORT = 5000; socket_bind($fd, "0.0.0.0", $PORT); while(true) { $remote_fd = socket_accept($fd); remote_socket_client_handle($remote_fd); } It is simple!

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