PHP+MYSQL 简单网站统计功能的实现 PV IP 真实访客数(UV)

主要统计三个数值，网站的pv 和ip 以及UV 真实访客数 因为有详细的统计记录，所以可以实现的功能还有很大的扩展！把tallydate使用内存表的话，速度就会更快了

需要用到二张表

CREATE TABLE `tally` (  
`date` date NOT NULL,  
`pvtotal` int(10) NOT NULL,  
`iptotal` int(10) NOT NULL,  
`dltotal` int(10) NOT NULL,  
PRIMARY KEY  (`date`)  
) ENGINE=InnoDB DEFAULT CHARSET=utf8;  
  
CREATE TABLE `tallydata` (  
`tdid` int(10) NOT NULL auto_increment,  
`ip` int(10) NOT NULL,  
`cookie` varchar(32) NOT NULL,  
`date` date NOT NULL,  
`time` int(10) NOT NULL,  
`uri` varchar(255) default NULL,  
`referer` varchar(255) default NULL,  
PRIMARY KEY  (`tdid`)  
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=5 ;

统计的调用文件（用于所在统计的页面进行js调入）：
(注：因项目使用的是ThinkPHP框架，所以贴出的只是代码片段！因为代码刚完成，所以没有做优化以及注释)

<?php  
class TallyAction extends Action{  
public function index(){  
if($_SERVER['SERVER_NAME']!=‘fullyee.com’ && $_SERVER['SERVER_NAME']!=‘www.fullyee.com’ && $_SERVER['SERVER_NAME']!=‘company.fullyee.com’) exit;  
$add['ip']=ip2long(get_client_ip());  
if(!Cookie::is_set(‘fullyeetally’)){  
$value=md5(microtime().$add['ip'].rand());  
  
$overTime=mktime(0,0,0,date(‘m’),date(‘d’)+1,date(‘Y’))-time();  
Cookie::set("fullyeetally",$value,time()+$overTime);  
}  
$fullyeetally=Cookie::get(‘fullyeetally’);  
$add['cookie']=$fullyeetally;  
$add['date']=date(‘Y-m-d’);  
$add['time']=time();  
$add['uri']=$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];  
$add['referer']=$_SERVER['HTTP_REFERER'];  
$tallydata_=D(‘Tallydata’);  
$tallydata_->create($add);  
$tallydata_->add();  
  
}  
  
public function saveData()  
{  
$tally_=D(‘Tally’);  
$tallydata_=D(‘Tallydata’);  
$nowDate=date(‘Y-m-d’,time()-3600*24);  
  
$now['date']=$nowDate;  
$now['iptotal']=$this->gototal($nowDate,‘ip’);  
$now['pvtotal']=$tallydata_->count(array(‘date’=>$nowDate),‘tdid’);  
$now['dltotal']=$this->gototal($nowDate,‘cookie’);  
  
if($tally=$tally_->find(array(‘date’=>$nowDate))){  
$tally_->save(array(‘iptotal’=>$now['iptotal'],‘pvtotal’=>$now['pvtotal'],‘dltotal’=>$now['dltotal']),array(‘date’=>$nowDate));  
}else{  
$tally_->create($now);  
$tally_->add();  
}  
$timeDel=time()-3600*24*50;  
$tallydata_->query("delete from `tallydate` where `time`<$timeDel");  
echo ‘Success ‘+date(‘Y-m-d H:i:s’);  
}  
  
function gototal($nowDate,$a)  
{  
$tallydata_=D(‘Tallydata’);  
$now['iptotal']=$tallydata_->query("select count(distinct $a) from `tallydata` where `date`=’$nowDate’ ");  
return $now['iptotal'][0]["count(distinct $a)"];  
}  
}  
?>

程序中的 saveDate 部分，用于服务器的定时运行，最简单的方法就是用linux的crontab在一个访问人数比较少的时间wget一下saveDate代码就行了。。这段代码的作用是，把前一天的访问数据全部统计，以天为单位写入tally表！并且删除一定时间外的统计记录。默认是删除50天以前的全部统计记录
显示部分：

$now['dltotal']=$this->gototal($nowDate,‘cookie’);  
  
if($tally=$tally_->find(array(‘date’=>$nowDate))){  
$tally_->save(array(‘iptotal’=>$now['iptotal'],‘pvtotal’=>$now['pvtotal'],‘dltotal’=>$now['dltotal']),array(‘date’=>$nowDate));  
}else{  
$tally_->create($now);  
$tally_->add();  
}  
$today['pv']=$now['pvtotal'];
