If you already have the ids comma delimited...

$query = '
   SELECT *
     FROM `brands`
    WHERE `id` IN (' . $brands . ')';

If not, use implode(',', $ids).

If your ids are from user input and not already made safe, use...

$ids = implode(',', array_map('intval', explode(',', $ids)));

"select * from brands where id in (".$brands.");"
