我正在使用 Zend Youtube API。我查询了一个提要，报告它总共有 886 个条目，但是当我获取所有提要并迭代时，实际数字是 782。

实际上是否存在不匹配，或者我忽略的代码中是否存在一些愚蠢的错误？

片段（debug() 只是一个方便的报告功能）：

$query = $yt->newVideoQuery($queryUrl);
$query->setMaxResults(50); //Max allowed, to reduce API hits
$feeds = array();
try {
  $feed = $yt->getVideoFeed($query);
  $totalResults = $feed->getTotalResults(); //For debug
  $feeds[] = $feed;
  $totalFromFeeds = sizeof($feed); //For debug
  while ($feed = $feed->getNextFeed()) {
    $feeds[] = $feed;
    $totalFromFeeds += sizeof($feed); //For debug
  }
} catch (Zend_Gdata_App_Exception $e) {
  debug("$e"); //For debug
  //Just means no more feeds; do nothing
}
$numFeeds = sizeof($feeds); //For debug

$entries = array();
foreach ($feeds as $feed) {
  foreach ($feed as $entry) {
    $entries[] = $entry;
  }
}
$numEntries = sizeof($entries); //For debug
debug("According to feed, [$totalResults]; sizeof entries = [$numEntries] 
Num Feeds: $numFeeds;   totalfromfeeds: $totalFromFeeds");

调试输出：

exception 'Zend_Gdata_App_Exception' with message 'No link to next set of results found.
According to feed, [886]; sizeof entries = [782] 
Num Feeds: 16;   totalfromfeeds: 782

感谢您的任何指点，

克里斯

<openSearch:totalResults> 值只是一个估计值。有关更多信息，请参阅文档：https ://developers.google.com/youtube/2.0/reference#Total_Result_Counts
