提取信息

我有以下的數組：提取信息

有一些值I需要提取到一個數組，subcomittess是lenght 0的一個字符串，但在這種情況下具有6個塊並且每個塊都是一個數組，但是，我怎樣才能獲得子合作伙伴和管轄權的信息？

我一直在這個工作幾個小時，我找不到解決方案，我會感謝您的幫助。

謝謝

此問題尚不清楚。你是什麼意思你想「獲得小組委員會和管轄權的信息」？提供你嘗試過的東西以及它失敗的例子。 – pocketfullofcheese

您是否期望'subcommittees'成爲指向一組對象的關鍵？如果是這樣，你的代碼不是這種情況。子數組本身沒有密鑰。 –

這個數組來自哪裏？如果它是你的代碼創建它，你需要在那裏尋找一個錯誤，像'$ your_array [] = $ subcommittee;'而不是'$ your_array ['subcommittees'] [] = $ subcommittee;'。 –

這6個塊不屬於subcomittess的一部分。它們是相同數組的值，可以通過它們的鍵訪問：0,1,2,3,4,5。

這是真的，但我懷疑問題出在首先創建數組的代碼中，正如@ Don'tPanic所述。 – Barmar
