使用NYT API访问JSON

Question

I'm currently using the NYT News API to search for articles. I'm trying to get the Article Name, and URL from the JSON. How do I do this for each entry in the JSON?

$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);

It returns a large JSON, I'm interested in retrieving the weburl, and headline field. I've tried:

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

and

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

but with no success. Any thoughts?

I also need all the entries that have a web_url and headline in the JSON.

A single article entry from the JSON response:

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

The Json Weburl data in the JSON can be accessed using the line: $y['response']['docs'][0]['web_url']

The 0 can be replaced with an index variable such as i to retrieve multiple web_url entries, and placed in a for loop.

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