帝国cms做相关链接的时候，会碰到这样的问题，判断两个以","号分割分割的字符串是否含有交集，那么就可以使用MySQL正则匹配的方式进行判断。
看代码：
<?php
$navinfor[keyboard]='批量,提取,李时珍,黄芪,帝国,图片,标题';
$jhc_key=','.str_replace(',',',|,',$navinfor['keyboard']).',';
$t=$dbtbpre."ecms_news";
$jieguo="";
$h = $empire->query("select * FROM $t where concat(',',keyboard,',') regexp '$jhc_key' limit 10");
while($r = mysql_fetch_assoc($h)){
echo $r['title'],$r['keyboard'],PHP_EOL;
}
?>
如果是帝国内容页的话，用灵动标签可以这样调用：
<?php
$jhc_key=','.str_replace(',',',|,',$navinfor['keyboard']).',';
$jhc_key1=str_replace(',','|',$navinfor['keyboard']);
?>
[e:loop={"select * from phome_ecms_news where id<>'$navinfor[id]' and ( title regexp '$jhc_key1' or concat(',',keyboard,',') regexp '$jhc_key') order by id desc limit 10",0,24}]
