To broadcast a message to all clients, you can use socket_write() for all required clients:... // Handle Input foreach ($clients as $key => $client) {if (in_array($client, $read)) {... if ($buf == 'message') {$talkback = "$buf $key\n"; foreach ($clients as $curClient) {socket_write($curClient, $talkback, strlen($talkback));} continue;}...}}...
