使用PHP在ARRAY中訪問數據

我不確定如何訪問ARRAY中的數據，如下面所示。使用PHP在ARRAY中訪問數據

作爲即時嘗試獲得summonerId，但它不會得到它。

我當前的代碼是：

$ getTierlist =所有數據showen

$summonerId = $getTierlist['summonerId'];

我也曾嘗試

$summonerId = $getTierlist->summonerId;

和

$summonerId = $getTierlist['29161162']->summonerId;

並沒有什麼會工作。我怎樣才能得到我想要的數據呢？

是如何從你的最後一個問題http://stackoverflow.com/questions/40441456/accessing-data-from-json-in-php此不同 – Barmar

嘗試轉換是JSON輸出數組第一：

$theList = json_decode($getTierlist, TRUE); 
var_dump($theList['29161162']['summonerId']));

我已經將它轉換爲數組，這只是代碼的一部分，以便從數組中獲得我需要的內容 – ForsakenHound

好吧，那麼它看起來像一個多維數組。可能是這樣的： – Zach

foreach（$ theList as $ key => $ subkey） { $ summonerId = key（$ key）; 的foreach（$的thelist [$ summonerId] [ '頁']爲$頁=> $數據） {// 做$頁和$數據東西}} 我 – Zach

你的變量$ getTierlist似乎是一個JSON字符串，而不是一個PHP數組。你需要將其轉換爲一個PHP數組，然後才能訪問它的元素，比如一個數組：

$getTierlist_Array = json_decode($getTierlist, true);

注意的第二個參數，真實的，這意味着該函數返回一個對象而不是一個數組。做好以上後，您可以訪問summonerId這樣的：

$summmonerId = $getTierList_Array['29161162']['summonerId'];

如何將返回它作爲一個數組想？ – ForsakenHound

將第二個參數設置爲true的函數json_decode就是這樣做的。 – NavkarJ
