使用活动记录在Yii2中创建radioList

Question

$list = [];
foreach($choices as $choice)
{
    ArrayHelper::map($list, $choice->id, $choice->choice_text);            
}
echo $form->field($model, 'choice_text')->radioList($list)->label(false);

$choices从包含模型选择的所有对象的视图传递。我需要创建一个将$choice->id映射到$choice->choice_text的数组。我该怎么办呢？

Answer 1

$list = ArrayHelper::map($choices, 'id', 'choice_text');
$form->field($model, 'id')->radioList($list)->label(false);

Answer 2

$list = [];
foreach($choices as $choice)
{
    $list = $list + [$choice->id=>$choice->choice_text];            
}
echo $form->field($model, 'choice_text')->radioList($list)->label(false);
