PHP解析JSON数据

<?php 

$jsonString = '{"errcode":0,"errmsg":"ok"}';

// 将JSON字符串转换为PHP对象
$dataObject = json_decode($jsonString);

// 将JSON字符串转换为PHP关联数组
$dataArray = json_decode($jsonString, true);

// 使用数据
echo $dataObject->errcode;
echo $dataArray['errcode'];

遍历是这样

$provinces = json_decode($response, true);
foreach($provinces['data']['list'] as $value){
  echo "{$value['title']}<br>";
  echo "{$value['url']}<br>";
  echo "{$value['v_url']}<br>";
  echo "{$value['cover_watermark']}<br>";
 }
