Attach link to attachments in wall.post method in vk

It is wall.post to attach a link at the end of a post in VK via vk api using the wall.post method in the attachments parameter.

  // загрузка фото на сервер $attachments = $v->upload_photo(0, array('img/1.jpg')); // публикация на стене $response = $v->api('wall.post', array( 'owner_id' => -xxxxxx, 'message'=>'я публикую фотографии', 'attachments' => implode(',', $attachments) ) 

I tried to add a line with a link to the attachments array in various ways, after which there is neither a link nor an image.

Here is the class V itself:
