yii\base\BaseObject

BaseObject is the base class that implements the property feature.
Property names are case-insensitive.

• Besides the property feature, BaseObject also introduces an important object initialization life cycle. In particular,
• creating an new instance of BaseObject or its derived class will involve the following life cycles sequentially:

1. the class constructor is invoked;
2. object properties are initialized according to the given configuration;
3. the init() method is invoked.
   In the above, both Step 2 and 3 occur at the end of the class constructor. It is recommended that you perform object initialization in the init() method because at that stage, the object configuration is already applied.
