        'username' => 'DB_USER',
        'password' => 'DB_PASS',
        // additional can be passed options, server-role and pool name:
        // 'option'     => [
        //     PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'UTF8'",
        //     PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
        // ],
        // 'role'       => 'master', // or slave
        // 'pool_name'  => 'default', // pool list of connections
    ],
    // possible another connection config
    // for the implementation of master-slave
]);

Query execution

$stm = AEngine\Database\Db::query('SELECT * FROM `user` WHERE `age` > 23');

while ($a = $stm->fetch(PDO::FETCH_ASSOC)) {
    // some action
    var_dump($a);
}
