Hello @kartik,
Delete an existing Model
$user = User::find(1);
$user->delete();
Deleting An Existing Model By Key
User::destroy(1);
User::destroy([1, 2, 3]);
User::destroy(1, 2, 3);
In every cases, the number between brackets represents the object ID, but you may also run a delete query on a set of models:
$affectedRows = User::where('votes', '>', 100)->delete();
