使用帝国cms的时候，需要调用当前文章的其他相关的文章，根据关键字相关的方式，代码如下
fetch1("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 1");
if($r[title])
{
$mesql=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 10");
while($or=$empire->fetch($mesql))
{
$newstime=date('Y-m-d',$or[newstime]);
?>
">
query("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." order by rand() desc limit 10");
while($r2=$empire->fetch($mesql2))
{
$newstime=date('Y-m-d',$o2[newstime]);
?>
">
query("select titleurl,title,newstime from {$dbtbpre}ecms_news order by rand() desc limit 10");
while($r2=$empire->fetch($mesql2))
{
$newstime=date('Y-m-d',$r2[newstime]);
?>
">
注释：就是我们不填写关键字的时候，随机调用文章，如果我们添加了关键字，没有相关的文章，也是随机调用文章
