php - strcoll() expects parameter 1 to be string in uasort() -

i need sort array contains strings different languages. best way found following:

setlocale(lc_collate, 'tr_tr.utf8'); // or other locale use. uasort($ainput['values'],'strcoll'); 

even though uasort works perfectly, has problems integers , shows warning:

strcoll() expects parameter 1 string

should loop whole array , cast integer values string before calling uasort or there other way?

you can try sort multi-dimensional using locale settings.

array_multisort($ainput['values'], sort_locale_string);
