How to represent Attributes with Anonymous Alphabets in view blade in Laravel - laravel

Question

I have this code in Laravel-5.8:
public function index()
{
$userCompany = Auth::user()->company_id;
$departments = HrDepartment::where('company_id', $userCompany)->get();
return view('hr.departments.index')->with('departments', $departments);
}
view
#foreach($departments as $key => $department)
<tr>
<td>
{{$key+1}}
</td>
<td>
{{$department->dept_name ?? '' }}
</td>
<td>
{{isset($department->dept_code) ? $department->dept_code : 'N/A'}}
</td>
</tr>
#endforeach
I don't want the user to see the real department name ( {{$department->dept_name ?? '' }}), but to make it anonymous.
That is, it can randomize {{$department->dept_name ?? '' }} and represent each with alphabets. The first one can be A, second B, C, .... Z
How do I achieve this?
Thanks

You can use this simple function using the ID of the department
function toAlphabet($integer){
$alphabet = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
$alpha_flip = array_flip($alphabet);
if($integer <= 25){
return $alphabet[$integer];
}
elseif($integer > 25){
$dividend = ($integer + 1);
$alpha = '';
$modulo;
while ($dividend > 0){
$modulo = ($dividend - 1) % 26;
$alpha = $alphabet[$modulo] . $alpha;
$dividend = floor((($dividend - $modulo) / 26));
}
return $alpha;
}
}
you can then do
toAlphabet($department->id);
//26 will give "AA"
//25 will give "Z"
//19682 will give "ACCA"
