Implementation code for grabbing Yahoo boss search results through curl under PHP

1. Write the curl class to capture web page content
Copy the code The code is as follows:
class CurlUtil
{
private $curl;
private $timeout = 10;
/**
* Initialize curl object
*/
public function __construct()
{
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0 ; Windows NT 5.1; SV1)");
curl_setopt($this->curl, CURLOPT_HEADER, false); //Set whether to display header information
curl_setopt($this->curl, CURLOPT_NOBODY, false); // Set whether to output page content
curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT, $this->timeout);
curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($this->curl , CURLOPT_AUTOREFERER, true);
}
/**
* Unregister function close curl object
*/
public function __destruct()
{
curl_close($this->curl);
}
/**
* Get the content of the web page
*/
public function getWebPageContent($url)
{
curl_setopt($this->curl, CURLOPT_URL, $url);
return curl_exec($this->curl);
}
}


2. Create curl object
Copy code The code is as follows:
$CurlUtil = new CurlUtil();

3. Grab yahoo search results
Copy the code The code is as follows:
function getYahooSearch(CurlUtil $curl, $key)
{
$key = urlencode($key);
$searchUrl = "http://boss.yahooapis.com/ysearch/web/v1/$key?appid=Your Yahoo appid&lang=tzh®ion=hk&abstract=long&count=20&format=json&start=0&count=10";
$ josnStr = $curl->getWebPageContent($searchUrl);
$searchDataInfo = json_decode($josnStr, true);
$searchData = $searchDataInfo['ysearchresponse']['resultset_web'];
$returnArray = array();
if (!empty($searchData)) {
foreach ($searchData as $data) {
$returnArray[] = array("url" => $data['url'], "date" => $ data['date'], 'title' => strip_tags($data['title']), 'description' => strip_tags($data['abstract']));
}
}
return $returnArray ;
}

4. Test results
var_dump(getYahooSearch($CurlUtil, "Baidu"));
