Laravel: how to remove item from Collection by id

Question

I want to remove the admin user from my collection. I know its the primary key in the table (id) is 1. But when I use forget(1) it deletes the array element in the collection starting from 0. How do I remove the item from the collection by the id?

    // Grab all the users
    $users = User::all(); //$this->user;  use to return array not Laravel Object
    if($users->find(1)->hasRole('admin'))
        $users->forget(0);

Answer 1

As such bencohenbaritone's answer is better way to resolve this problem, I have to add that Laravel Eloquent Collection has method except(), which can remove Eloquent objects from the collection by primary key instead of forget(). The latter one removes by collection index key (like array[i]) and not by primary key.

So you can write something like (sorry about the bad example, my own use case is too different to be useful for others):

$admin_user_id = 20;
$users = User::all();
$users_without_admin = $users->except($admin_user_id);
