How to write native PHP.

$host = '服务端IP';    $port = 端口号;    $timeout = 5;    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);    if (socket_connect($socket, $host, $port) === false) { // 创建连接
        socket_close($socket);        $message = 'create socket error';        throw new Exception($message, socket_last_error());
    }   

    if (socket_write($socket, $buffer) === false) { // 发包
        socket_close($socket);        $message = sprintf("write socket error:%s", socket_strerror(socket_last_error()));        throw new Exception($message, socket_last_error());
    }   

    socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $timeout);    $rspBuffer = socket_read($socket, 65536); // 接收回包

    socket_close($socket);

Use swoole writing method.

$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_SYNC);$ret = $client->connect('服务端IP', 端口号, 0.5, 0);  // 创建连接if (!$ret) {
    throw new Exception('connect error', $client->errCode);
}   

$client->send($buffer); // 发包$rspBuffer = $client->recv(); // 接收回包
