For yii2, First Make a folder named "components" in your project root folder.

Then write your custom component inside components folder .i.e MyComponent.php or anything.

namespace app\components;

use Yii;
use yii\base\Component;
use yii\base\InvalidConfigException;

class MyComponent extends Component
{
  public function MyFunction($param1,$param2){
    return $param1+$param2; // (:)
  }
}

Now add your component inside the config file.

'components' => [

     'mycomponent' => [

        'class' => 'app\components\MyComponent',

        ],
       ]

Access in your app:

Yii::$app->mycomponent->MyFunction(4,2);

If it's shared only within the controller, you could just create a function inside it. The components in Yii2 should be use for Application purposes (to be shared between more than one controller).

  private function myFunction(a, b){
      return a+b;
  }

And then call it from anywher in your controller

public function actionSomeAction(){
   if(myFunction(1,2)>4){...}
}

Also the ideas of the component is to have more functionality that just a function, for example to have all users' behavior.
