我从yahoo boss api获得这个json输出。它持续了50个结果，但是，我只粘贴了前两个......

我在php中使用以下代码连接到api并显示结果......

      **//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>';
}
      ?>

我的问题是如何对结果进行分页，因为所有50个结果仅显示在第一个网页上。我想在每个页面显示十个结果。

感谢任何帮助。

感谢。

根据Yahoo! BOSS文档，特别是Universal Arguments section，看起来您可以使用start和count参数来调整结果的分页。看起来默认的返回计数是50，与您观察到的匹配。

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;
