使用 PHP foreach 解析 JSON 数组

2021-12-26 00:00:00 json foreach php

想知道为什么我的 PHP 代码不会在 JSON 数据中显示值"的所有值":

Wondering why my PHP code will not display all "Value" of "Values" in the JSON data:

$user = json_decode(file_get_contents($analytics));
foreach($user->data as $mydata)
{
     echo $mydata->name . "
";

}        
foreach($user->data->values as $values)
{
     echo $values->value . "
";
}

第一个 foreach 工作正常，但第二个会引发错误.

The first foreach works fine, but the second throws an error.

{
   "data": [
      {
         "id": "MY_ID/insights/page_views_login_unique/day",
         "name": "page_views_login_unique",
         "period": "day",
         "values": [
            {
               "value": 1,
               "end_time": "2012-05-01T07:00:00+0000"
            },
            {
               "value": 6,
               "end_time": "2012-05-02T07:00:00+0000"
            },
            {
               "value": 5,
               "end_time": "2012-05-03T07:00:00+0000"
            }, ...

推荐答案

您可能想要执行以下操作:

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "
";
         foreach($mydata->values as $values)
         {
              echo $values->value . "
";
         }
    }
