|

|
* |
|
|
|
|
* - create the object using the PHP `new` operator; |
|
|
|
|
* - if [[Yii::objectConfig]] contains the configuration for the object class, |

|
|
|
* it will be merged with the $config parameter; |
|
|
|
|
* - initialize the object properties using the configuration passed to this method; |
|
|
|
|
* - call the `init` method of the object if it implements the [[yii\base\Initable]] interface. |
|
|
|
|
* |
|
|
|

|
|
|
|
* |
|

|
|

|
* } |
|
|
|
|
* |
|
|
|
|
* $model = Foo::newInstance(array('c' => 3), 1, 2); |
|
|
|
|
* // which is equivalent to the following lines: |
|
|
|
|
* $model = new Foo(1, 2); |
|
|
|
|
* $model->c = 3; |
|
|
|
|
* $model->init(); |
|
|
|
|

|

* @param array $config the object configuration (name-value pairs that will be used to initialize the object) |
|
