How to use PHP to implement a simple online event registration system
With the rapid development of the Internet, more and more activities are beginning to manage registration through the online registration system process, eliminating the trouble of traditional paper registration forms and manual processing. This article will introduce how to use PHP language to implement a simple online event registration system, and use specific code examples to help readers understand and practice.
System Requirements Analysis
Before developing a system, it is first necessary to clarify the requirements and functions of the system. Based on the characteristics of the event registration system, we can determine the following functional requirements:
- Users can browse the detailed information of the event and fill in the registration form.
- After the user fills out the form, the system will save the user's registration information and send an email to the user to confirm the registration.
- The administrator can log in to the system management backend to view registration details and count the number of applicants.
- The administrator can export the registration information to Excel or CSV format files.
System design and database construction
Before starting to write PHP code, we need to design the database table structure and create the corresponding database table. Here we create two tables: one is the activity table, used to store basic information about the activity; the other is the registration table, used to store the user's registration information.
The activity table structure is as follows:
activity_id (int, primary key) activity ID
activity_name (varchar) activity name
activity_date (datetime) activity date
activity_location (varchar) activity location
...
The registration table structure is as follows:
registration_id (int, primary key) Registration ID
activity_id (int) Activity ID
name (varchar) Name
email (varchar) Email
phone (varchar) Phone
...
PHP code implementation
Next, we start writing PHP code to implement the system's functions. The first is the display and form submission processing of the user registration page.
<!DOCTYPE html>
<html>
<head>
<title>活动报名系统</title>
</head>
<body>
<h1 id="活动报名">活动报名</h1>
<form action="submit.php" method="post">
<p>
<label for="name">姓名:</label>
<input type="text" id="name" name="name" required>
</p>
<p>
<label for="email">邮箱:</label>
<input type="email" id="email" name="email" required>
</p>
<p>
<label for="phone">电话:</label>
<input type="tel" id="phone" name="phone" required>
</p>
<input type="submit" value="报名">
</form>
</body>
</html>The above code shows a simple registration form page. After the user fills out the form, clicking the "Sign Up" button will submit the data to submit.php for processing.
<?php
$activity_id = 1; // 假设活动ID为1
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
// 保存用户报名信息到数据库
$conn = mysqli_connect("localhost", "root", "", "activity_registration");
$sql = "INSERT INTO registration (activity_id, name, email, phone) VALUES ('$activity_id', '$name', '$email', '$phone')";
mysqli_query($conn, $sql);
// 发送邮件给用户确认报名
$to = $email;
$subject = "活动报名确认";
$message = "您已成功报名参加活动。";
$headers = "From: admin@example.com";
mail($to, $subject, $message, $headers);
echo "报名成功！";
?>The above code saves the registration information submitted by the user to the database, and uses PHP's mail function to send an email to the user to confirm the registration.
Next, we write the login and registration information management functions of the administrator backend.
<!DOCTYPE html>
<html>
<head>
<title>管理员登录</title>
</head>
<body>
<h1 id="管理员登录">管理员登录</h1>
<form action="admin.php" method="post">
<p>
<label for="username">用户名:</label>
<input type="text" id="username" name="username" required>
</p>
<p>
<label for="password">密码:</label>
<input type="password" id="password" name="password" required>
</p>
<input type="submit" value="登录">
</form>
</body>
</html>The above code shows a simple administrator login interface. After the administrator fills in the correct user name and password, it will be submitted to admin.php for processing.
<?php
$username = $_POST['username'];
$password = $_POST['password'];
// 管理员登录验证
if ($username == "admin" && $password == "password") {
// 登录成功，显示报名信息页
$conn = mysqli_connect("localhost", "root", "", "activity_registration");
$sql = "SELECT * FROM registration";
$result = mysqli_query($conn, $sql);
while ($row = mysqli_fetch_assoc($result)) {
echo "姓名: " . $row['name'] . "<br>";
echo "邮箱: " . $row['email'] . "<br>";
echo "电话: " . $row['phone'] . "<br>";
echo "<hr>";
}
} else {
// 登录失败，显示错误提示
echo "用户名或密码错误！";
}
?>The above code verifies the administrator's username and password. If the verification is passed, the registration information is queried from the database and displayed to the administrator.
Summary and Outlook
Through the above sample code, we have learned how to use PHP language to implement a simple online event registration system. Of course, this is just a basic implementation. In practice, more functions and detailed optimizations can be added according to needs. I hope this article can help readers better understand and use PHP to implement their own registration system.

How do you set the session cookie parameters in PHP?Apr 22, 2025 pm 05:33 PMSetting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.
What is the main purpose of using sessions in PHP?Apr 22, 2025 pm 05:25 PMThe main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.
How can you share sessions across subdomains?Apr 22, 2025 pm 05:21 PMHow to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.
How does using HTTPS affect session security?Apr 22, 2025 pm 05:13 PMHTTPS significantly improves the security of sessions by encrypting data transmission, preventing man-in-the-middle attacks and providing authentication. 1) Encrypted data transmission: HTTPS uses SSL/TLS protocol to encrypt data to ensure that the data is not stolen or tampered during transmission. 2) Prevent man-in-the-middle attacks: Through the SSL/TLS handshake process, the client verifies the server certificate to ensure the connection legitimacy. 3) Provide authentication: HTTPS ensures that the connection is a legitimate server and protects data integrity and confidentiality.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
