限制同IP注册人数代码_PHP教程

今天我们来看看限制同IP注册人数代码的代码吧,注要用到datediff 函数哦,很简单的.

$ex_sql =mysql_query("Select * from wk_member where m_ip='$ip' and datediff(m_dtime,'$dtime')=0");
   if(mysql_num_rows($ex_sql)     $sql;
     if(mysql_query($sql)){      
       $_SESSION['uid']=array(mysql_insert_id(),$uid,$mo);           
       exit("<script>location='registerok.php';</script>");
     }else{
       alert('注册失败!','');
     }
   }else{
    alert('对不起,同IP一天只能注册5个用户','');
   }
