I am getting this json output from yahoo boss api. It goes on for 50 results, but, I have pasted only the first two...

    (
        [bossresponse] => stdClass Object
            (
                [responsecode] => 200
                [web] => stdClass Object
            (
                [start] => 0
                [count] => 50
                [totalresults] => 2750000
                [results] => Array
                    (
                        [0] => stdClass Object
                            (
                                [date] => 
                                [clickurl] => http://www.apple.com/ipad/
                                [url] => http://www.apple.com/ipad/

                            )

                            )

I use the following code in php to connect to the api and display the results...

      **//connect to yahoo api and get results in json**
      <?php
      require("OAuth.php");

    $cc_key  = "**confidential**";
    $cc_secret = "**confidential**";
    $url = "http://yboss.yahooapis.com/ysearch/web";
    $args = array();
    $args["q"] = "yahoo";
    $args["format"] = "json";

    $consumer = new OAuthConsumer($cc_key, $cc_secret);
    $request = OAuthRequest::from_consumer_and_token($consumer, NULL,"GET", $url, $args);
    $request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL);
    $url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args));
    $ch = curl_init();
    $headers = array($request->to_header());
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $rsp = curl_exec($ch);
    $results = json_decode($rsp);
    ?>
    **// Present results in html/php**
    <div id="resultsdiv">
    <?php
     foreach($results->bossresponse->web->results as $result) 
      {
echo '<h3><a href='.$result->url.'>'.$result->title.'</br>'.$result->abstract.'</a></h3>';
}
      ?>

My question is how do I paginate results, since all the 50 results appear on the first web page only. I want to display ten results in every page.

Any help is appreciated.

Thanks.

根据雅虎！BOSS 文档，特别是Universal Arguments 部分，看起来您可以使用start和count参数来调整结果的分页。看起来默认返回计数为 50，与您观察到的相符。

在您的代码示例中，您可以通过添加进行调整：

$args["start"] = 0; // increment as needed
$args["count"] = 10;
