How to remove index number from laravel eloquent unique

Question

I am using a query that returns value perfectly but it adds key number to the collection. How can I remove the index number?

Here is the retrieved data

Answer 1

You have to do it manually

   $users=\App\User::get()->toArray(); // your query here 
   $data['data']=[];
   foreach($users as $user ){ 
         $data['data'][]=$user; 
    }
   $k=json_encode($data); dd($k);

Answer 2

In order to get a collection without a index you have to add the "values" method

$collection->unique('id')->values();
