## 新建core/Config.php ``` <?php namespace core; class Config { protected $config = []; // 掃描 config 文件夾,加入到配置的大數組 public function init() { foreach (glob(FRAME_BASE_PATH.'/config/*.php') as $file){ $key = str_replace('.php','',basename($file)); $this->config[$key] = require $file; } } // 獲取配置 public function get($key) { $keys = explode('.',$key); $config = $this->config; foreach ($keys as $key) $config = $config[$key]; return $config; } // 重置配置的值 public function set($key, $val) { $keys = explode('.', $key); $newconfig = &$this->config; foreach($keys as $key) $newconfig = &$newconfig[$key]; // 傳址 $newconfig = $val; } } ``` ### 綁定配置 `app.php`  ### 加載配置  現在 配置信息已經完成了,接下來是運行下看看。 ### 創建config/database.php ``` <?php return [ 'default' => 'hello world', 'connections' => [ 'mysql_one' => [ 'driver' => 'mysql', 'host' => '134.175.80.215', 'username' => 'php_frame', 'dbname' => 'php_frame', 'password' => '12345678', 'prefix' => '', 'options' => [ ] ], ] ]; ``` ### 編輯routes/web.php ``` $router->get('/config',function (){ echo App::getContainer()->get('config')->get('database.connections.mysql_one.driver').'<hr/>'; App::getContainer()->get('config')->set('database.connections.mysql_one.driver','mysql set'); echo App::getContainer()->get('config')->get('database.connections.mysql_one.driver'); }); ```
