最近一直再讀GateWayWorkerman源碼 遇到一點(diǎn)困惑希望得到幫助。在GatewayWorker/Lib/Gateway.php文件中有一些TCP的問(wèn)題不是很理解。

  /**
     * 發(fā)送buffer數(shù)據(jù)到網(wǎng)關(guān)
     * @param string $address
     * @param string $gateway_buffer
     * @return bool
     */
    protected static function sendBufferToGateway($address, $gateway_buffer)
    {
        // 有$businessWorker說(shuō)明是workerman環(huán)境，使用$businessWorker發(fā)送數(shù)據(jù)
        if (self::$businessWorker) {
            if (!isset(self::$businessWorker->gatewayConnections)) {
                return false;
            }
            return self::$businessWorker->gatewayConnections->send($gateway_buffer, true);
        }
        // 非workerman環(huán)境
        $gateway_buffer = self::$secretKey ? self::generateAuthBuffer() . $gateway_buffer : $gateway_buffer;
        $flag           = self::$persistentConnection ? STREAM_CLIENT_PERSISTENT | STREAM_CLIENT_CONNECT : STREAM_CLIENT_CONNECT;
        $client         = stream_socket_client("tcp://$address", $errno, $errmsg, self::$connectTimeout, $flag);
        return strlen($gateway_buffer) == stream_socket_sendto($client, $gateway_buffer);
    }

這個(gè)函數(shù)中非workerman環(huán)境 啟動(dòng)了一個(gè)Socket客戶端 發(fā)送完數(shù)據(jù)后不用調(diào)用關(guān)閉socket的命令么？
還有在 sendAndRecv函數(shù)中也沒(méi)有見(jiàn)到關(guān)閉Socket函數(shù)的命令，這些打開(kāi)過(guò)的客戶端Socket不需要顯示關(guān)閉么？
難道是等待心跳超時(shí)GateWay端來(lái)關(guān)閉么？
