PHP Development Guide: How to implement real-time website visitor statistics
Introduction:
In today’s Internet era, website traffic statistics are crucial to website operation and optimization . Real-time visitor statistics are a means of instantly understanding website visitors. This article will introduce how to use PHP to develop a simple real-time website visitor statistics system to provide more comprehensive data support for website operations.
1. Preparation:
2. Database design:
We need to create a data table named "visitors" to store real-time visitor information. The table structure is as follows:
CREATE TABLE visitors ( id INT PRIMARY KEY AUTO_INCREMENT, ip VARCHAR(45) NOT NULL, time DATETIME NOT NULL );
3. Create a web page file:
4. Main page design:
The following is a simple main page design example:
<!DOCTYPE html> <html> <head> <title>网站实时访客统计</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <h1>欢迎访问网站!</h1> <div class="visitor-info"> <p>当前在线人数:<span id="online-count"></span></p> </div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="visitor.js"></script> </body> </html>
This page mainly contains an element that displays the number of people currently online, which is used to After the page is loaded, obtain the real-time number of visitors through an AJAX request.
5. Write JavaScript code:
In the "visitor.js" file, write the following JavaScript code:
$(document).ready(function() { setInterval(updateVisitors, 1000); }); function updateVisitors() { $.ajax({ url: 'visitor.php', type: 'post', data: {'action': 'count'}, success: function(response) { $('#online-count').text(response); } }); }
This code snippet will write to "visitor.php every 1 second "Send an AJAX request to get real-time visitor counts and update the page with the results.
6. Write PHP code:
In the "visitor.php" file, write the following PHP code:
<?php // 连接数据库 $conn = new mysqli('数据库主机名', '用户名', '密码', '数据库名'); // 检查连接是否成功 if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } // 获取请求类型 $action = $_POST['action']; if ($action == 'count') { // 获取实时访客数量 $result = $conn->query("SELECT COUNT(*) as count FROM visitors"); $row = $result->fetch_assoc(); echo $row['count']; } elseif ($action == 'record') { // 记录访客信息 $ip = $_SERVER['REMOTE_ADDR']; $time = date('Y-m-d H:i:s'); $stmt = $conn->prepare("INSERT INTO visitors (ip, time) VALUES (?, ?)"); $stmt->bind_param("ss", $ip, $time); if ($stmt->execute()) { echo '记录成功'; } else { echo '记录失败'; } } // 关闭数据库连接 $conn->close(); ?>
This code snippet performs different operations based on the request type. If the request type is "count", the real-time number of visitors is returned; if the request type is "record", the current visitor's IP address and timestamp are recorded.
7. Write CSS styles:
In the "style.css" file, write the following CSS styles:
h1 { text-align: center; } .visitor-info { text-align: center; margin-top: 50px; font-size: 18px; }
This style is mainly used to beautify the display effect of the page.
8. Deployment and testing:
