Multiple connections

[ilyagory]

Ability to use multiple connections.

How to use it

1. create a mysqlidb instance with params for the 1st database

$db = new MysqliDB($host, $username, $password);

2. add params for the 2nd database (via addConnection method)

$db->addConnection('second', ['host'=>$host2, 'username'=>$username2, 'password'=>$password2]);

3. switch to the 2nd connection for the next query via connection

$db->connection('second')->get('seconddb_table');

... or the 1st connection will be used

$db->get('firstdb_table');

ps.: selected connection (step 3) will be unselect after request done (at reset method).
