循環通過嵌套數組PHP

Question

我有以下結構（我在PHP中使用json_decode遍歷它）：

{"721":{"forms":0},"722":{"forms":"[82]","ope":"48723","ini":"01/03/2015 00:00","fin":"01/03/2015 00:20"},"723":{"forms":0},"724":{"forms":0},"725":{"forms":0},"726":{"forms":0},"727":{"forms":0},"729":{"forms":0},"730":{"forms":0},"731":{"forms":0}} 

如何訪問屬性「形式」？

Answer 1

使用foreach循環遍歷數組中的每個鍵/值對，然後訪問值數組的forms屬性。

$a = json_decode($stuff, true); // where $stuff is that JSON string 
foreach ($a as $key => $value) { 
    print $value['forms']."<br />" 
}
