laravel 记录错误日志到数据库：
​​​https://github.com/markhilton/monolog-mysql​​

在.env里面加上这两个全局变量:

DB_LOG_TABLE=debug_logs
DB_LOG_CONNECTION=mysql

composer require markhilton/monolog-mysql
php artisan vendor:publish
php artisan migrate

Open up config/app.php and find the providers key.

'providers' => array(
    // ...
    Logger\Laravel\Provider\MonologMysqlHandlerServiceProvider::class,
);

In your application bootstrap/app.php add:

$app->configureMonologUsing(function($monolog) use($app) {
    $monolog->pushHandler(new Logger\Monolog\Handler\MysqlHandler());
});
