Is there any way to convert ActiveRecord to an array in Yii2? I do know we can do that for ActiveQuery, for example User::find()->asArray()->one();, but can we convert Model to array when it is already fetched? I want to do that in beforeSave() method and store that array in cache.

Try this!
$model = Post::find($id)->limit(10)->asArray()->all();
$model = Post::find($id)->select('id,name as full')->asArray()->one();
$model = Post::find($id)->select('id,name as full')->asArray()->all();
$model = Post::find()->where(['slug'=>$slug])->asArray()->one();

This answer is far more optimal
Boolean_Type
TS noted: But can we convert Model to Array when it is already fetched. So, that answer is not very useful.

From Yii2 guide - use ArrayHelper::toArray():
$posts = Post::find()->limit(10)->all();
$data = ArrayHelper::toArray($posts, [
'app\models\Post' => [
'id',
'title',
// the key name in array result => property name
'createTime' => 'created_at',
// the key name in array result => anonymous function
'length' => function ($post) {
return strlen($post->content);
},
],
]);

I would like to add that ActiveRecord also has a function
toArray(), so $model->toArray() would also work for converting a single model after it is fetched.

Hi @scaisEdge it's not a question, it's extra information to point out that there's also the function
toArray() you can use.ScaisEdge
@JelmerKeij yes i kwon is function of activeRecord yiiframework.com/doc-2.0/yii-db-activerecord.html
For one model it's sufficient to use a property attributes
$User = User::find()->one();
$user_as_array = $User->attributes;

Thank you! I'm new in Yii2, and it's a few difficult to make chains like
$model->search($request->get())->getModels()[0]->attributes for example, for debug. Becouse all works via magic methods and IDE can't help.
