关于php的判断语句
$pubdate = $dsql->GetOne("select pubdate from article where writer ='".$writer."' order by id desc limit 1");
if((time()-$pubdate['pubdate'])<(3600*24)){
ShowMsg("对不起，一个会员每天只能发一篇文章！","-1","0",5000);
exit;
}
以上判断一个会员在一天内只能提交一篇文档，想修改成可以提交3篇，应该怎么做？
------解决方案--------------------
原代码改为
$n = 1; //你指定的篇数
$pubdate = $dsql->GetOne("select count(*) as cnt from article where FROM_UNIXTIME(pubdate,'%Y%m%d')=DATE_FORMAT(now(),'%Y%m%d') and writer ='".$writer."' order by id desc limit 1");
if($pubdate['pubdate'] > $n){
ShowMsg("对不起，一个会员每天只能发 $n 篇文章！","-1","0",5000);
exit;
}
