How to display an array in radioList in yii2?

Question

Yii

there is a line in the post table where the json array is stored with the name of the sites and their links
. After Json::decode, this array takes this form
array(3) {
[0]=> array(2) {
["title"]=> string (90) "Site1"
["link"]=> string(32) " site1.ru "
}
[1]=> array(2) {
["title"]=> string(39) " Site2"
["link "]=> string(28) " site2.ru "
}
[2]=> array(2) {
["title"]=> string(56) "Site2"
["link"]=> string(27) " site3.en "
}
}
you need to list them in the radioList form so that the name is clickable
. here is the form itself, I don’t understand how to properly insert this array there.

<?= $form->field($model, 'site')->radioList([
    
           //тут должен быть массив
    ],   [
                                'item' => function($index, $label, $name, $checked, $value) {

                                    $return = '<label class="modal-radio">';
                                    $return .= '<input type="radio" name="' . $name . '" value="' . $value . '" tabindex="3">';
                                    $return .= '<i></i>';
                                    $return .= '<span>' . ucwords($label) . '</span>';
                                    $return .= '</label><br/>';

                                    return $return;
                                }
                            ]
                        ); ?>

Good morning.

$arr = [
    [
        "title"=> "Сайт1",
        "link"=> "site1.ru"
    ],
    [
        "title"=> " Сайт2",
        "link"=> "site2.ru"
    ],
    [
        "title"=> "Сайт2",
        "link"=> "site3.ru"
    ]
];

<?= $form->field($model, 'email')->radioList(ArrayHelper::map($arr, 'title', 'link'),[
    'item' => function($index, $label, $name, $checked, $value) {
        return '<label class="modal-radio" style="display:block;">
                  <input type="radio" name="' . $name . '" value="' . $value . '" tabindex="3">
                  <i></i>
                  <span>' . ucwords($label) . '</span>
               </label>';
    }
]) ?>
