我有一个多维数组。我需要对数组中具有相同索引名称的值进行分组和求和。下面是我所拥有的：

Array
(
[Garlic Potatoes] => 625
[Rice] => 1025
[Chicken Shawarma] => 1675
[Pita Bread Sm] => 6
[Pita Bread Large] => 14
[Beef Shawarma] => 1755
[Can of Pop] => 2
[Brioch Bun] => 2
[Chicekn Shawarama] => 135
)

我怎样才能得到一个Chicken Shawarma的示例，并且qty = 1405？我需要使用foreach吗？

$sql = "SELECT menu_id, SUM(quantity) AS qty FROM daily_consumption_details WHERE consumption_id = $id GROUP BY menu_id";
$res = $conn->query($sql);

$ingredients = [];

while($menu = $res->fetch_object())
{

    $sql_ing = "SELECT item_name, quantity FROM menu_details WHERE menu_id = $menu->menu_id ";
    $rs = $conn->query($sql_ing);
    while($items = $rs->fetch_object())
    {
        $qty = $menu->qty * $items->quantity;
    
        if ( array_key_exists(trim($items->item_name), $ingredients) ) 
            $ingredients[trim($items->item_name)] = $qty + $ingredients[trim($items->item_name)];
        else 
            $ingredients[trim($items->item_name)] = $qty; 

    }
}
