PHP中如何进行RPC框架的开发？

interface RemoteService {
    function hello($name);
}

class RemoteServiceImpl implements RemoteService {
    function hello($name) {
        return "Hello, $name!";
    }
}

$server = stream_socket_server('tcp://0.0.0.0:1234', $errno, $errstr);
if (!$server) {
    die("Failed to create server: $errno - $errstr");
}
while ($socket = stream_socket_accept($server)) {
    // 处理客户端请求
}

while ($socket = stream_socket_accept($server)) {
    $data = fread($socket, 1024);
    $data = unserialize($data);
    $class = $data['class'];
    $method = $data['method'];
    $args = $data['args'];
    $impl = new $class();
    $ref = new ReflectionMethod($class, $method);
    $result = $ref->invokeArgs($impl, $args);
    fwrite($socket, serialize($result));
    fclose($socket);
}

class RpcClient {
    private $socket;
    private $host;
    private $port;

    public function __construct($host, $port) {
        $this->host = $host;
        $this->port = $port;
        $this->socket = stream_socket_client("tcp://$host:$port", $errno, $errstr);
        if (!$this->socket) {
            die("Failed to create socket $errno - $errstr");
        }
    }

    public function __destruct() {
        fclose($this->socket);
    }

    public function call($class, $method, $args) {
        $data = serialize(array('class'=>$class, 'method'=>$method, 'args'=>$args));
        fwrite($this->socket, $data);
        $result = fread($this->socket, 1024);
        $result = unserialize($result);
        return $result;
    }
}

$client = new RpcClient('127.0.0.1', 1234);
$result = $client->call('RemoteServiceImpl', 'hello', array('World'));
echo $result; // Hello, World!
