比如招聘和求职，企业会员只出招聘，普通会员只出求职

<?php$modsql=$empire->query("select mid,qmname from {$dbtbpre}enewsmod where usemod=0 and showmod=0 and qenter<>'' order by myorder,mid");while($modr=$empire->fetch($modsql)){if(getcvar('mlgroupid')==个人会员组ID&&$modr[mid]==招聘系统模型ID){continue;}if(getcvar('mlgroupid')==企业会员组ID&&$modr[mid]==求职系统模型ID){continue;}?><li><img src="/skin/member/images/list.gif" /><a href="/e/DoInfo/ListInfo.php?mid=<?=$modr[mid]?>"><?=$modr[qmname]?></a><em><a href="/e/DoInfo/ChangeClass.php?mid=<?=$modr[mid]?>">发布</a></em></li><?}?>

可以同时能写多个会员组id

if((getcvar('mlgroupid')==企业会员组ID||getcvar('mlgroupid')==会员组ID2)&&$modr[mid]==求职系统模型ID
