遍历结果并汇总并吐出php

Question

我在下面的代码中尝试完成的工作：它执行SELECT ，它应该返回（2）个结果，这些结果各拉〜10个项目（总项目：〜20个），并将其显示在页面上。

实际发生的情况：它拉出第二个结果，因此仅在可能的20个结果中输出约10个结果。因此， $result var在循环后实际上应该总共有约20个项目……但它只有10个。已经测试了实际的输出和查询...

有什么想法吗？

Answer 1

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

您在这里对$newsStory了破坏性分配，我假设它是一个数组，所以请使用$newsStory[] = ...
