php How to achieve the number of visitors?

PHP accurately implements page visit statistics

1. Two database tables are required

①, IP record table

create table ip (ipid int(11) NOT NULL default '',ipdata varchar(16) NOT NULL default '',iptime varchar(30) NOT NULL default '', primary key(ipid));

Note: ipdata is the recorded ip of the visitor, iptime is the recorded ip access

②, statistics table

create table count (todayipcount int(11) NOT NULL default '',allipcount int(11) NOT NULL default '',day varchar(2) NOT NULL  default '');
insert into count (todayipcount,allipcount,day) values ('0','0','0');

2, implementation method

In your case Put the following code on the page that counts the number of times:

$realip=getip();
modifyipcount($realip);

The code of the getip() function is:

function getip()
{
        if (isset($_SERVER)) 
        {
                if (isset($_SERVER[HTTP_X_FORWARDED_FOR]) && strcasecmp($_SERVER[HTTP_X_FORWARDED_FOR], "unknown"))//代理
                {
                        $realip = $_SERVER[HTTP_X_FORWARDED_FOR];
                } 
                elseif(isset($_SERVER[HTTP_CLIENT_IP]) && strcasecmp($_SERVER[HTTP_CLIENT_IP], "unknown"))
                {
                        $realip = $_SERVER[HTTP_CLIENT_IP];
                } 
                elseif(isset($_SERVER[REMOTE_ADDR]) && strcasecmp($_SERVER[REMOTE_ADDR], "unknown"))
                {
                        $realip = $_SERVER[REMOTE_ADDR];
                } 
                else
                {
                        $realip = 'unknown';
                }
        } 
        else
        {
                if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
                {
                        $realip = getenv("HTTP_X_FORWARDED_FOR");
                }
                elseif(getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
                {
                        $realip = getenv("HTTP_CLIENT_IP");
                } 
                elseif(getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
                {
                        $realip = getenv("REMOTE_ADDR");
                } 
                else
                {
                        $realip = 'unknown';
                }
        } 
        return $realip;
}

Note: This function code can be found everywhere on the Internet

modifyipcount() function code is:

function modifyipcount($ip)
{
        <-----------------------数据库的连接省略------------------------->
        $query="SELECT * FROM ip where ipdata=&#39;".$ip."&#39;";
        $result=mysql_query($query);
        $row=mysql_fetch_array($result);
        $iptime=time();
        $day=date(&#39;j&#39;);
        if(!$row)
        {
                $query="INSERT INTO ip (ipdata,iptime) VALUES (&#39;".$ip."&#39;,&#39;".$iptime."&#39;)";
                mysql_query($query);
                $query="SELECT day,todayipcount,allipcount FROM count";
                $result=mysql_query($query);
                $row=mysql_fetch_array($result);
                $allipcount=$row[&#39;allipcount&#39;]+1;
                $todayipcount=$row[&#39;todayipcount&#39;]+1;
                if($day==$row[&#39;day&#39;])
                {
                        $query="UPDATE count SET allipcount=&#39;".$allipcount."&#39;,todayipcount=&#39;".$todayipcount."&#39;";
                }
                else
                {
                        $query="UPDATE count SET allipcount=&#39;".$allipcount."&#39;,day=&#39;".$day."&#39;,todayipcount=&#39;1&#39;";
                }
                 mysql_query($query);
        }
        else
        {
                $query="SELECT iptime FROM ip WHERE ipdata=&#39;".$ip."&#39;";
                $result=mysql_query($query);
                $row=mysql_fetch_array($result);
                $query="SELECT day,todayipcount,allipcount FROM count";
                $result=mysql_query($query);
                $row1=mysql_fetch_array($result);
                if($iptime-$row[&#39;iptime&#39;]>86400)
                {
                                                $query="UPDATE ip SET iptime=&#39;".$iptime."&#39; WHERE ipdata=&#39;".$ip."&#39;";
                 mysql_query($query);
                        $allipcount=$row1[&#39;allipcount&#39;]+1;
                        if($day==$row1[&#39;day&#39;])
                        {
                                $query="UPDATE count SET allipcount=&#39;".$allipcount."&#39;";
                        }
                        else
                        {
                                $query="UPDATE count SET allipcount=&#39;".$allipcount."&#39;,day=&#39;".$day."&#39;,todayipcount=&#39;1&#39;";
                        }
                         mysql_query($query);
                }
                if($day!=$row1[&#39;day&#39;])
                {
                        $query="UPDATE count SET day=&#39;".$day."&#39;,todayipcount=&#39;1&#39;";
                         mysql_query($query);
                }        
        }
}

Note: Here I set the number of access statistics within 24 hours to only add 1

so that we can call todayipcount and allipcount in the database table count I got today's access IP and total access IP. I personally think it is very accurate. Everyone is welcome to put forward different opinions.
