1. Simple statistics of files
Use php to implement a simple visitor statistics function, and count the total number of visits to the website, which is simple and practical. PHP opens the text file every time, gets the number in the text, adds 1 and writes it into the text. Therefore, as long as there is a visit every time, the number of simple visitors will be counted by accumulating the number of PVs.
<?php
if(!file_exists("count.txt")){
$one_file=fopen("count.txt","w+"); //建立一个统计文本，如果不存在就创建
echo"您是第<font color='red'><b>1</b></font>位访客"; //首次直接输出第一次
fwrite("count.txt","1"); //把数字1写入文本
fclose("$one_file");
}else{ //如果不是第一次访问直接读取内容，并+1,写入更新后再显示新的访客数
$num=file_get_contents("count.txt");
$num++;
file_put_contents("count.txt","$num");
$newnum=file_get_contents("count.txt");
echo"您是第<font color='red'><b>".$newnum."</b></font>位访客";
}
?>A simple program for php visitor statistics. The above code counts the number of pv of the website. In addition to counting the number of pv (number of page visits) in the website, there are also statistics of uv (number of user visits). This requires adding cookies to distinguish each page. If a user already has a cookie, it means that they have visited, and no accumulation will be performed. Code such as:
<?php
if(！empty($_COOKIE["access"]) && $_COOKIE["access"]==1){
if(!file_exists("count.txt")){
$one_file=fopen("count.txt","w+");
echo"您是第<font color='red'><b>1</b></font>位访客";
fwrite("count.txt","1");
fclose("$one_file");
setcookie("access",1, time()+3600*24); //访问过标记
}else{
$num=file_get_contents("count.txt");
$num++;
file_put_contents("count.txt","$num");
$newnum=file_get_contents("count.txt");
echo"您是第<font color='red'><b>".$newnum."</b></font>位访客";
setcookie("access",1, time()+3600*24);//访问过标记
}
}
?>2. Obtain detailed statistics
In a public file of the website, statistics on the user's IP, browser type, system type, access time, current address, access source, and IP-to-locality information are obtained for each visit. Through this information, you can roughly know which place has the largest number of visitors, which article has the largest number of visitors, the number of visitors today, pv, malicious access ip and other information will come out.
1. Database table structure:
CREATE TABLE `visitors` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'id',
`ip` char(30) DEFAULT NULL COMMENT 'ip地址',
`froms` char(100) DEFAULT NULL COMMENT '归属地',
`add_time` datetime NOT NULL COMMENT '添加时间',
`system` char(60) DEFAULT NULL COMMENT '操作系统',
`browser` char(200) DEFAULT NULL COMMENT '浏览器',
`pageview` char(200) DEFAULT NULL COMMENT '受访页面',
`source_link` varchar(1000) DEFAULT NULL COMMENT '来源链接',
PRIMARY KEY (`id`),
KEY `ip` (`ip`),
KEY `add_time` (`add_time`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='访客表';2. PHP statistics code
Place the code for obtaining information in a public php file and write it into the database.
