PHP slim的数据库会话

Question

I am trying to connect my sessions to a database with the PHP slim framework but I cant seem to connect. I am using the following middleware: https://github.com/yusukezzz/slim-session-manager

But the example shows the connection like:

$manager->setDbConnection(Eloquent::getConnection());

I am not using Eloquent. I have tried:

$manager->setDbConnection(mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE));

But get the error:

Argument 1 passed to Illuminate\Session\DatabaseSessionHandler::__construct() must be an instance of Illuminate\Database\Connection, instance of mysqli given

How can I pass an instance of Illuminate\Database\Connection ?
