Answer 2

您可以将PDO选项传递给连接（没有详细记录，但代码不会谎言：https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Connectors/Connector.php#L33）在 app / config / database.php 中，如下所示：

...

'connections' => [
        ...

        'mysql' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST', 'localhost'),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
            'engine'    => null,
            'dump_command_path' => '/opt/mysql/bin', 
            'options' => [
                PDO::ATTR_PERSISTENT => false //@todo
            ]
        ],

        ...
