How can I find out which model a sample belongs to?

Question

Laravel

Now the array includes those fields that are in the table (id, text).
Is it possible to somehow supplement this array, for each item, in order to
know which table this refers to?
Post::all()

#perPage: 15
      +exists: true
      +wasRecentlyCreated: false
      #attributes: array:2 [▼
        "id" => 1
        "text" => "Общие положения"
      ]
      #original: array:2 [▶]
      #changes: []
      #casts: []

I want to load all this from different models into one select for html and then I have to somehow filter which model this option belongs to

Answer 1

$collection->map(function ($item, $key) {
      $item->setAttribute('table', $item->getTable());
});

public function getTableAttribute()
  {
    return $this->getTable();
  }

Answer 2

Why merge something and then filter? You can not transfer two (or how many you have there) different collections or what?
