try this

$result = array();
function merge_values(array &$array, $mixed) {
    if(is_array($mixed)) {
        foreach($mixed as $tags) {
            merge_values($array, $tags);
        }
    }
    else {
        if(null !== $mixed && strlen($mixed) > 0 && false === array_search($mixed, $array)) {
            $array[] = $mixed;
        }
    }
}

merge_values($result, $array);
print_r($result);

Answer 2

I think you should try this

function uniqueElements($outerArray){
    $result=array();
    foreach ($outerArray as $innerArray){
      $result=array_merge($innerArray);
    }

return array_unique($result);
}

Answer 3

$result2 = array_unique(call_user_func_array('array_merge',$result2));
