I haver permissions levels system, so i need remove from my array my previos selected permissions. For example:

```
My permissions:  read, write
All permissions: read, write, update, delete
I need return:   update, delete

```

The problem: `array_diff_assoc`() compare exact keys, [0] = [0], i need compare values not keys, and return all permission without, my previos selected permissions, not removed values.

```
res['all_withou_pre_selected_permissions'] = array_diff_assoc($all_permissions,$res['my_permissions']);
print_r($res['all_withou_pre_selected_permissions']);

```

My arrays and return

```
