基于IP的简单网站访问量统计(已更新版优化SQL数据库)

基于IP的简单网站访问量统计，同一ip下一天只算一次的访问量 代码如下
mysql 代码

create table ipcount(
ip int(10) primary key not null

auto_increment,
nowdate varchar(255),
nowdatec varchar(255),
ip varchar(255)
)


b]控制器代码[[/b]

public function ipcount(){
$ip=get_client_ip(); //获取客户端IP
ini_set('date.timezone','Asia/Shanghai');//设置时区
$date=date('Y-m-d');//获取当前时间
$yesterday=date("Y-m-d",strtotime("-1 day")); //获取昨天时间
$yesterrow=M('ipcount')->field('nowdatec')->where('nowdate="'.$yesterday.'"')->select();
$yesterdayc=0;
for ($i=0;$i $yesterdayc+=$yesterrow[$i]['nowdatec'];
}
$row=M('ipcount')->field('ip')->where('nowdate="'.$date.'"')->select();//查找今天的记录
$n=1;
$add=array(
'nowdatec'=>$n,
'nowdate'=>$date,
'ip'=>$ip,
);
if(empty($row)){//判断并添加记录
M('ipcount')->add($add);
}
$iprow=M('ipcount')->field('ip')->where('ip like "%'.$ip.'%" and nowdate="'.$date.'"')->select();//查找今天的ip记录
$ipcount=$row[0]['ip'];
if(empty($iprow)){ //判断并更新IP和统计记录
$ipcount=$ipcount.$ip;
$row1=M('ipcount')->field('nowdatec')->where('nowdate="'.$date.'"')->select();
foreach($row1 as $cd){
$dd= $cd['nowdatec'];
}

$dd+=1;
$save=array(

'nowdate'=>$date,
'ip'=>$ipcount,
