Question

我目前正在使用NYT News API搜索文章。我试图从JSON获取文章名称和URL。如何为JSON中的每个条目执行此操作？

$curl = curl_init();
$call = 'http://api.nytimes.com/svc/search/v2/articlesearch.json?    q=Denmark&begin_date=20040112&end_date=20041212&sort=oldest&api-key=mykey';

curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => $call,
    CURLOPT_USERAGENT => 'Codular Sample cURL Request'
));
// Send the request & save response to $resp
echo $resp = curl_exec($curl);
curl_close($curl);

//Decode Json
$y = json_decode($resp,true);

它返回一个大型JSON，我对检索weburl和标题字段感兴趣。我试过了：

$url = $y['response']['docs']['web_url']

和

$headline = $y['response']['docs']['headline']

但没有成功。有什么想法吗？

我还需要所有在JSON中都有web_url和标题的条目。

The silver has a warmth to it, whether the style is 1900, Art Deco or modern.'' Last year, the company Georg Jensen founded celebrated its 100th anniversary.

Answer 1

可以使用以下行来访问JSON中的Json Weburl数据：$ y ['response'] ['docs'] [0] ['web_url']

可以使用索引变量（例如i）替换0以检索多个web_url条目，并将其置于for循环中。

for(i=0;i<3;i++)
{
$y['response']['docs'][i]['web_url']
}
