How to use PHP to implement website visit statistics

In today's Internet world, understanding website visits is crucial for website administrators and developers of. By counting website access data, we can understand website traffic, user behavior and other information, thereby providing a basis for website optimization and improvement. This article will introduce how to use PHP to implement the website's visit statistics function, and provide relevant code examples for readers' reference.

First of all, before implementing website visit statistics, we need to know that PHP is a server-side scripting language that can be embedded into HTML. PHP can obtain user access information through interaction with the server and store this information in a database or file. Below we will implement the website visit statistics step by step.

The first step is to create the database and data table.

First, we need to create a database to store access statistics. This can be done using MySQL, SQLite or other database systems. In the database, we need to create a data table to store the website's access logs.

The following is a sample MySQL database and data table creation command:

CREATE DATABASE `website_statistics`;

USE `website_statistics`;

CREATE TABLE `access_log` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `ip` VARCHAR(50) NOT NULL,
  `page_url` VARCHAR(255) NOT NULL,
  `access_time` DATETIME NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

The second step is to write PHP code to count and record website access data.

In each page of the website, we need to add the following PHP code to the top of the page in order to count user access data.

<?php
// 配置数据库连接信息
$host = 'localhost';  // 数据库服务器主机地址
$dbName = 'website_statistics';  // 数据库名
$user = 'root';  // 数据库用户名
$password = '123456';  // 数据库密码

// 连接数据库
$pdo = new PDO("mysql:host=$host;dbname=$dbName;charset=utf8", $user, $password);

// 获取用户的IP地址和访问页面的URL
$ip = $_SERVER['REMOTE_ADDR'];
$pageUrl = $_SERVER['REQUEST_URI'];

// 将访问日志插入数据库
$sql = "INSERT INTO `access_log` (`ip`, `page_url`, `access_time`) VALUES (?, ?, NOW())";
$statement = $pdo->prepare($sql);
$statement->execute([$ip, $pageUrl]);
?>

In the above code, we first configure the database connection information, including database host address, database name, database user name and database password. Then, use the $_SERVER variable to get the user's IP address and the URL of the page being accessed. Finally, use the PDO function to insert into the database and insert the user's access information into the access_log data table.

The third step is to query and display the website access statistics.

By querying the access log data stored in the database, we can obtain website access statistics. The following is a simple PHP code example for querying and displaying website visit statistics.

<?php
// 连接数据库
$pdo = new PDO("mysql:host=$host;dbname=$dbName;charset=utf8", $user, $password);

// 查询访问统计数据
$sql = "SELECT COUNT(*) AS `total_visits` FROM `access_log`";
$statement = $pdo->prepare($sql);
$statement->execute();
$result = $statement->fetch(PDO::FETCH_ASSOC);

// 展示访问统计数据
echo "网站总访问量：".$result['total_visits']."次";
?>

In the above code, we use SQL statements to query the number of records in the access_log table in the database, that is, the total number of visits to the website. Then, use PHP’s echo function to display the queried access statistics on the website page.

Through the above three steps, we can implement a simple website visit statistics function. Of course, based on actual needs, we can also expand and improve these functions, such as recording the user's browser type, operating system and other information, analyzing the user's access behavior, etc. We hope that readers can practice and explore more functions related to website access statistics through the sample code provided in this article.
