1 // Detach a single role from the user...
2 $user->roles()->detach($roleId);
3
4 // Detach all roles from the user...
5 $user->roles()->detach();
For convenience, attach and detach also accept arrays of IDs as input:
1 $user = App\User::find(1);
2
3 $user->roles()->detach([1, 2, 3]);
4
5 $user->roles()->attach([1 => ['expires' => $expires], 2, 3]);

If you need to update an existing row in your pivot table, you may use updateExistingPivot
method:
1 $user = App\User::find(1);
2

array will exist in the intermediate table:
1 $user->roles()->sync([1, 2, 3]);
You may also pass additional intermediate table values with the IDs:
