See more:

$result = $stmt->fetchAll(PDO::FETCH_COLUMN);
   if($result)
            return get_item_name(explode(' ','-1','0', $result[0]));
   else {
        return 'Empty';
        }

Warning: explode() expects at most 3 parameters, 4 given in vault.php on line 43

get_item_name_locale_name is other function that give names to each number

Database Column Data [6673 6669 4860 6670 -1 6671 6672 169 166 173 -1 -1 15 15 18 15 0 15 15 0 0 0 0 0]
"space","0","-1" must be ignored , somehow bigger than 1 must show

Thank you very much

What I have tried:

 if ($result) {
    return array_map(function ($row) {
        get_item_name_locale_name($row);
    }, $result);
} else {
    return '---';
}

i got error Notice: Array to string conversion in vault.php on line 57 Array

Your code, 4 parameters:

explode(' ','-1','0', $result[0])

vs. PHP: explode - Manual[^] 3 parameters

explode(string $separator, string $string, int $limit = PHP_INT_MAX): array

I think should be easy for you to solve. I hope it helps.
