php-2つの配列を比較してマージするためのヘルプが必要ですか？

同じデータベースからの次の2つの配列があり、同じクエリを使用して両方を取得しています。両方に、2つの異なるラインアイテム（材料の請求書）を持つ単一の販売注文に関する情報が含まれています。最初のラインアイテムにはラインアイテム ItemID= 600271 があり、2番目のラインアイテムにはLineItem{-code-があります。 2} ですが、以下に示すように、どちらも同じ販売注文番号 [CustomerSONo] => [7] => **15020**を持っています。

私が抱えている問題： Built in functions を使おうとしましたが、2つを比較してマージし、違いを保存するループを作成するのに苦労しています別の変数で。

では、これら2つの配列を比較または結合するにはどうすればよいですか。 ？
