我想用下面的代码完成什么：它执行SELECT，它应该返回（2）个结果，这些结果每个拉动约 10 个项目（总项目：~20）并在页面上显示这些结果。

实际发生的情况：它提取第二个结果，因此在可能的 20 个结果中仅输出 ~10 个结果。因此，$resultvar 在循环后应该总共有 ~20 个项目......但它只有 10 个......我已经测试了实际输出和查询...

有什么想法吗？

foreach($result as $r){
  $xmlUrl = $r['FW_ArtSrcLink'];
  $ConvertToXml = simplexml_load_file($xmlUrl);
  # -> Setup XML
  $newsStory = $ConvertToXml->channel->item;
}

您对$newsStory此处进行了破坏性分配，我认为它是一个数组，因此请$newsStory[] = ...改用。
