php7은 어떻게 다른 프레임워크로부터 학습하고 자체 프레임워크를 작성합니까?

// 第一种，使用匿名函数
App::router()->get('/', function () {
    echo "Beauty Framework.";
});

// 第二种，使用url分发到控制器
App::router()->post('/user/info/[0-9]+(/[0-9]+)?', 'App\Controllers\UserController@getUserInfo');

if (is_string($lostrcallable) && preg_match('!^([\a-zA-Z0-9]+)\@([a-zA-Z0-9]+)$!', $lostrcallable, $matches)) {
            $class  = $matches[1];
            $method = $matches[2];

            $callable = function () use ($class, $method) {
                static $obj = null;
                if ($obj === null) {

                    $obj = new $class;
                }

                return call_user_func_array(array($obj, $method), func_get_args());
            };
        }

    /**

     *
     * @access public
     * @param integer|array $limit Array to define SQL limit in format Array ($count, $offset)
     *                             or only $count

     * @return mixed Array of Clients

    protected function get($limit = null)
    {
        $this->dbClient->setQueryChannel($this->channel);

        $results = $this->dbClient->arrayBuilder()->get($this->dbTable, $limit, $this->fields);
        $this->_reset();

        if ($this->dbClient->count == 0) {
            return [];
        }

        return $results;

; This is a environment configuration file

// 支持使用.连接访问配置项，访问的是config/app.php中的config key
\Beauty\Core\App::config()->get("app.config");
