Thanks guys, But I needed the word corresponding with the number.
It wasn't written anywhere...
So I had to host a server to find it. For those who need it :
case '0':
$mode= 'None';
break;
case '1':
$mode= 'Very Few';
break;
case '2':
$mode= 'Few';
break;
case '3':
$mode= 'Often';
break;
case '4':
$mode= 'Very Often';
break;
case '5':
$mode= 'Max';
break;
