下面给出的是我的 json 数组，我在做了一个

$data = json_decode($response);

foreach($data[songs] as $key => $value) {
 echo $value['title']; 
}

我收到一条错误消息，提示此非法字符串偏移“歌曲”。任何人都可以帮忙吗？

{
   "response":{
      "status":{
         "version":"4.2",
         "code":0,
         "message":"Success"

一个简单的json_decode($jsonstring)将返回 stdClass 对象和数组的混合。字符串键是对象属性，JSON 数组是 PHP 数组，从索引 0 开始。

用于json_decode($jsonstring, true)仅获取带有字符串键的数组。

只要做 var_dump($data) 你的错误就会很明显。

试试这个：

foreach($data->response->songs as $song) {
    print_r($song);
}

你有两个问题。您没有访问该response属性，并且您没有将结果json_decode()视为对象。

我不确定，但我想你不能访问数据['songs'] 而不先抛出'response'
