Yii2 - ActiveRecord到Array

Question

有没有办法将ActiveRecord转换为Yii2中的数组？我知道我们可以为ActiveQuery执行此操作，例如User::find()->asArray()->one();，但是当它已经被提取时我们可以将Model转换为数组吗？我希望在beforeSave()方法中执行此操作，并将该数组存储在缓存中。

Answer 1

从Yii2 guide - 使用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);
        },
    ],
]);

Answer 2

试试这个！

$model = Post::find($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();

Answer 3

对于一个模型，使用属性attributes

就足够了

$User = User::find()->one();
$user_as_array = $User->attributes;
