PHP查找带有图像的项目，并在顶部包含

while循环中的前两个if/elseif语句检查新闻项是否存在图像，如果不存在，则跳过它。计数器确保只对顶部的前三个项目执行此操作。目前，这可以正常工作，没有任何错误

我希望前两个if/elseif语句只使用带有图片$row->imagelibid的帖子-因此7天前可能有一个带有图片的新闻故事，所以它在顶部使用它-它被迫查找并使用带有图片的新闻故事。这将意味着这些“选定”故事的日期顺序将是错误的——但这没关系

希望这有意义。。。以及任何我感激的帮助

p.S我知道mysql_uu是一个不推荐使用的函数，但如果现在可以忽略这一点，那就好了。

只需循环所有结果，如果找到一个图像，将其保存到一个数组中，比如$newsWithImage，如果找不到，则将$newsWithoutImage保存到另一个数组中。 完成后，只需在第一个数组中循环并回显结果，然后取另一个数组

while ( ( $row = mysql_fetch_object( $result ) ) !== false )
{
   if($row->imagelibid)
      $newsWithImage[] = $row;
   else
      $newsWihtoutImage[] = $row;
}

foreach($newsWithImage as $news)
{
  // do your html output with the results 
}

foreach($newsWithoutImage as $news)
{
  // do your html output with results
}
