activerecord - yii2 get getter's value in active query request (using asArray()) -

i have next code:

    $fixed_events = eventmain::find()         ->select(["id", "title", "files"])         //->joinwith(['files'])         //->with(['files'])         ->asarray()         ->all(); 

how can array "files" value, taking account, "files" modle's getter

public function getfiles() {     return (json_decode($this->all_files, true)) ?: []; }  

since files not relation eventmain table, guess easiest approach handle data , convert arrayhelper after coming db:

<?php use yii\helpers\arrayhelper;   $models = eventmain::find()->select(['id', 'title'])->all();  $array = arrayhelper::toarray($models, [     'app\models\eventmain' => ['id', 'title','files'] ]);  var_dump($array); ?>
