defined('YII_DEBUG') or define('YII_DEBUG', true); defined('YII_ENV') or define('YII_ENV', 'dev');

if (YII_ENV_DEV) { // configuration adjustments for 'dev' environment $config['bootstrap'][] = 'debug'; $config['modules']['debug'] = [ 'class' => 'yii\debug\Module', // uncomment the following to add your IP if you are not connecting from localhost. 'allowedIPs' => ['127.0.0.1', '我的IP'], ]; $config['bootstrap'][] = 'gii'; $config['modules']['gii'] = [ 'class' => 'yii\gii\Module', // uncomment the following to add your IP if you are not connecting from localhost. 'allowedIPs' => ['127.0.0.1', '我的IP'], ]; }
