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-------------------------> $query="SELECT * FROM ip where ipdata='".$ip."'"; $result=mysql_query($query); $row=mysql_fetch_array($result); $iptime=time(); $day=date('j'); if(!$row) { $query="INSERT INTO ip (ipdata,iptime) VALUES ('".$ip."','".$iptime."')"; mysql_query($query); $query="SELECT day,todayipcount,allipcount FROM count"; $result=mysql_query($query); $row=mysql_fetch_array($result); $allipcount=$row['allipcount']+1; $todayipcount=$row['todayipcount']+1; if($day==$row['day']) { $query="UPDATE count SET allipcount='".$allipcount."',todayipcount='".$todayipcount."'"; } else { $query="UPDATE count SET allipcount='".$allipcount."',day='".$day."',todayipcount='1'"; } mysql_query($query); } else { $query="SELECT iptime FROM ip WHERE ipdata='".$ip."'"; $result=mysql_query($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['iptime']>86400) { $query="UPDATE ip SET iptime='".$iptime."' WHERE ipdata='".$ip."'"; mysql_query($query); $allipcount=$row1['allipcount']+1; if($day==$row1['day']) { $query="UPDATE count SET allipcount='".$allipcount."'"; } else { $query="UPDATE count SET allipcount='".$allipcount."',day='".$day."',todayipcount='1'"; } mysql_query($query); } if($day!=$row1['day']) { $query="UPDATE count SET day='".$day."',todayipcount='1'"; 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.
