Yii2 - ActiveRecord 到数组 [英] Yii2 - ActiveRecord to Array

问题描述

有没有什么方法可以将 ActiveRecord 转换为 Yii2 中的数组?我知道我们可以为 ActiveQuery 做到这一点，例如 User::find()->asArray()->one();，但我们可以转换Model 已经获取到数组?我想在 beforeSave() 方法中做到这一点，并将该数组存储在缓存中.

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.

推荐答案

来自 Yii2 指南 - 使用 ArrayHelper::toArray():

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);
        },
    ],
]);
