How to pass a link correctly?

Question

Yii

The link field (string(2048)) is stored in the database.
In the view, I add a link to the a tag.

<?= Html::a(ссылка, $myObject->link, ['target'=>'_blank'])?>

Problem:
If you insert a link like this:
https://toster.ru/
then the link will open the site "toaster", and if you insert it like this:
toster.ru
it opens https:
//my-domain.loca/toster.ru , please, how to make it so that, regardless of the type of link, sites (though not correct ones) open without my domain?

Answer 1

Add // - //toster.ru
Or store the full url with http.
