Question

请找到json iam接收：

 {  
 "batchcomplete":"",
 "continue":{  
  "sroffset":10,
  "continue":"-||"
  },
   "query":{  
  "searchinfo":{  
     "totalhits":1937
  },
  "search":[  
     {  
        "ns":0,
        "title":"India",
        "pageid":15557,
        "size":213703,
        "wordcount":30816,
        "snippet":"<span class=\"searchmatch\">India</span> (Hindi: \u092d\u093e\u0930\u0924 or Bharat) is the largest country in the Indian subcontinent and shares borders with Pakistan to the northwest, China and Nepal to",
        "timestamp":"2018-05-27T12:16:15Z"
     },
     {  
        "ns":0,
        "title":"Southern India",
        "pageid":33554,
        "size":20350,
        "wordcount":2534,
        "snippet":"South <span class=\"searchmatch\">India</span> includes five major states in peninsular <span class=\"searchmatch\">India</span> and the two island groups of Lakshadweep in the Arabian Sea on the West Coast of <span class=\"searchmatch\">India</span> and Andaman",
        "timestamp":"2018-05-13T14:30:50Z"
     }}

我试图使用php检索数据。

我的PHP代码如下。

curl_setopt ($curl, CURLOPT_URL, 'https://en.wikivoyage.org/w/api.php?action=query&list=search&srwhat=text&srsearch=India&format=json');  
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
$xml = curl_exec ($curl);  

if ($xml === false) {
    die('Error fetching data: ' . curl_error($curl));  
}

curl_close ($curl); 

echo htmlspecialchars("$xml", ENT_QUOTES);

$data = json_decode($xml); 
foreach ($data->query as $country) 
{ 
    echo $country->searchinfo; 
}

但我在这行收到错误.echo $ country-＆gt; searchinfo;该错误表明未定义的属性：stdClass :: $ searchinfo。

我正在尝试仅检索片段变量（第一个）

有人可以帮助我。

1。$data->queryfo需要$data->query

2.您必须像这样更改foreach()： -

foreach ($data->query->search as $country) 
{ 
    echo $country->snippet;echo PHP_EOL; 
}

注意： - 我已按您所说的I am trying to receive the snippet and not totalhits

更改了代码

用php从json wikivoyage获取数据
