base\Module setModules()

Registers sub-modules in the current module.

Each sub-module should be specified as a name-value pair, where name refers to the ID of the module and value the module or a configuration array that can be used to create the module. In the latter case, Yii::createObject() will be used to create the module.

If a new sub-module has the same ID as an existing one, the existing one will be overwritten silently.

The following is an example for registering two sub-modules:

[
    'comment' => [
        'class' => 'app\modules\comment\CommentModule',
        'db' => 'db',
    ],
    'booking' => ['class' => 'app\modules\booking\BookingModule'],
]
