解碼的json字符串中的訪問字段PHP

Question

我試圖訪問該解碼的json字符串中使用php的第一首歌的字段'id'。我已經嘗試了所有可能的組合像這樣的：

$響應 - >歌曲[0] - > ID

這是我的解碼JSON字符串：

Array (
[response] => Array (
[status] => Array (
[version] => 4.2 
[code] => 0 
[message] => Success 
) 
[songs] => Array (
[0] => Array (

在此先感謝

Answer 1

$id = $json_array['response']['songs'][0]['id']; 

說明

看看反應，你的反應是一個多維ARRA這意味着你有一個由幾個數組組成的數組，每個數組可以包含一個或多個數組。

在你的第一個數組是「響應」，這其中包含了他們的休息，所以..

$id = $json_array['response'] 

此數組你，直到你得到你想要的元素裏面去築巢。其中包含到另一個陣列的歌曲，所以..

$id = $json_array['response']['songs'] 

這其中有幾個要素通過數字索引，只要你想從我們選擇的0元素的第一首歌曲的編號，

$id = $json_array['response']['songs'][0] 

後這個你可以得到元素你想要的：

$id = $json_array['response']['songs'][0]['id']; 

Answer 2

的json_decode返回數組，所以訪問你這樣做：

$id = $json_array['response']['songs'][0]['id']; 

如果你想在對象的方式來工作，你需要轉換：

$object = (object) $json_array; 
$object->response->songs[0]->id
