Yii2 - ActiveRecord to Array

Question

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();

TS noted: _But can we convert Model to Array **when it is already fetched**_. So, that answer is not very useful. – Boolean_Type Nov 17 '17 at 10:44

This doesn't answer the question, and this information was already in the question. – Coz Dec 13 '18 at 16:19

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. – Jelmer Keij Apr 11 '16 at 09:26

Hi @scaisEdge it's not a question, it's extra information to point out that there's also the function `toArray()` you can use. – Jelmer Keij Apr 12 '16 at 10:26
@JelmerKeij yes i kwon is function of activeRecord http://www.yiiframework.com/doc-2.0/yii-db-activerecord.html – scaisEdge Apr 12 '16 at 10:57

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. – Aleksej_Shherbak Jul 28 '20 at 09:54
