如何输出所选数组键的值

Question

现在从API获取json文件我需要使用数组中的值 这是一个假设

的例子

<?php
     $jsonData = {"responseCode":"8876","responseDetail":"success","accessToken":"098826sdftyajjla;"}

     $array = json_encode($jsonData);
     echo $array['accessToken'];

Answer 1

您无法使用必须首先解码json的数组来访问json_encoded数据，然后您可以访问值，例如

$json_data = '{"response_code":200,"response_status":"success","accessToken":"abcdef"}';
$data = json_decode($json_data);
echo $data->accessToken;

Answer 2

请试试这个

    <?php 
         $jsonData = '{"responseCode":"8876","responseDetail":"success","accessToken":"098826sdftyajjla;"}';
         $array = json_decode($jsonData);
         print_r($array->accessToken );
?>
