`$array['apple'] = array_unique($array['apple']); $array['banana'] = array_unique($array['banana']);` — splash58, Jul 07 '15 at 11:53

This should work for you:

Just loop through your array with array_map() and check if it is an array or not. If yes just return the unique array with array_unique(), else just return the value.

<?php

    $unique = array_map(function($v){
        if(is_array($v))
            return array_unique($v);
        return $v;
    }, $array); 

    print_r($unique);

?>
