    }
}
echo implode(",",$shops_list);

Answer 1

$shop_list is not defined, before using it in this line array_push($shops_list,$name_column);. And, this line

    array_push($shops_list,$name_column);

needs to be, as you need to mention the key name,

    array_push($shops_list,$name_column['name']); //or better
    $shop_list[] = $name_column['name'];
