在PHP变量中获取JSON对象的值 [英] Get value of JSON object in PHP variable

问题描述

我有以下JSON对象:

I have the following JSON object:

[Object, Object, Object, Object, Object, Object, Object, Object, Object, Object]
   0: Object
      category: Object
         0: "Value"

我想知道如何在PHP变量中获得值". 我以为category [0]会做到这一点，但是我得到了以下内容，而不是"Value":

I was wondering how I could get 'Value' in a variable in PHP. I thought category[0] would just do it but I get the following instead of 'Value':

 __proto__: Object 

我该怎么办?

推荐答案

您必须将JSON字符串转换为关联数组，这是通过json_decode()将第二个参数设置为true来完成的.

You have to converts the JSON string into associative array, which is done by json_decode() with second parameter set as true.

$var = json_decode($json, true); 
$value = $var['0']['category']['0'];
