如何在php中解析JSON字符串 [英] How to parse JSON string in php

问题描述

我得到了以下JSON响应:

I'm getting below JSON response:

[{"startDate":"2012-07-12 11:21:38 +0530","totalTime":0},{"startDate":"2012-07-11 11:27:33 +0530","totalTime":0},{"startDate":"2012-07-16 18:38:37 +0530","totalTime":0},{"startDate":"2012-07-17 14:18:32 +0530","totalTime":0}]

我想要开始日期和totalTime的数组，我已经使用了这两行，但是它不能工作$ obj，请提出建议.

i want make array of start date and totalTime, i have used these two lines but it wont work $obj, please suggest..

                    $obj  = json_decode($dateTimeArr); 
        $dateAr = $obj->{'startDate'}; 

推荐答案

正如大家所说，您做到了-使用json_decode.

As everyone said, and you did - use json_decode.

    $dateArrays  = json_decode($dateTimeArr, true); // decode JSON to associative array
    foreach($dateArrays as $dateArr){
        echo $dateArr['startDate']; 
        echo $dateArr['totalTime']; 
    }

将来，如果不确定变量中包含什么类型的数据或结构，请执行var_dump($var)，它将打印变量的类型及其内容.

In future, if you are unsure what type or structure of data is in the variable, do var_dump($var) and it will print type of variable and its content.
