循环通过嵌套数组PHP

Question

我有以下结构（我在PHP中使用json_decode遍历它）：

{"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}} 

如何访问属性“形式”？

Answer 1

使用foreach循环遍历数组中的每个键/值对，然后访问值数组的forms属性。

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