The second-hand recycling website uses the online reservation service function developed by PHP

Introduction:
With the rapid development of society and the increasing scarcity of resources, second-hand recycling has become an important environmental awareness and resource recycling method of utilization. In order to meet the needs of users and improve user experience, many second-hand recycling websites have begun to introduce online appointment service functions. This article will introduce how to use PHP to develop the reservation service function of a simple second-hand recycling website.

Development environment preparation:

A server with PHP installed;
A database that supports MySQL;
A text editor.

Database design:
Before you start writing code, you first need to design the database. We need to create two tables, one to store user information and the other to store reservation information.

User table (user_table):
Fields: id, name, phone, address

Appointment table (appointment_table):
Fields: id, user_id, date, time, remark

Code implementation:

Create database connection:

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
?>

Create reservation function page:

<!DOCTYPE html>
<html>
<head>
    <title>二手回收预约</title>
</head>
<body>
    <h1 id="预约二手回收">预约二手回收</h1>
    <form method="post" action="submit.php">
        <label for="name">姓名：</label>
        <input type="text" name="name" required><br>

        <label for="phone">电话：</label>
        <input type="text" name="phone" required><br>

        <label for="address">地址：</label>
        <input type="text" name="address" required><br>

        <label for="date">日期：</label>
        <input type="text" name="date" required><br>

        <label for="time">时间：</label>
        <input type="text" name="time" required><br>

        <label for="remark">备注：</label>
        <textarea name="remark"></textarea><br>

        <input type="submit" value="提交">
    </form>
</body>
</html>

Processing appointment submission requests:

<?php
include 'db_connect.php'; // 连接数据库

$name = $_POST['name'];
$phone = $_POST['phone'];
$address = $_POST['address'];
$date = $_POST['date'];
$time = $_POST['time'];
$remark = $_POST['remark'];

// 插入预约信息
$sql = "INSERT INTO appointment_table (user_id, date, time, remark)
VALUES ('$name', '$phone', '$address', '$date', '$time', '$remark')";

if ($conn->query($sql) === TRUE) {
    echo "预约成功！";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

Summary:
Through the above code example, we can see how to use PHP to develop the appointment service function of a simple second-hand recycling website. Users can fill in the reservation form through the website, and the server saves the reservation information submitted by the user into the database. In this way, both users and website administrators can easily manage and process appointment requests, improving user experience and website operation efficiency. The introduction of this function not only improves the service quality of second-hand recycling websites, but also further promotes the popularization of environmental awareness and recycling of resources.

How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AM

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Define the term 'session hijacking' in the context of PHP.Apr 29, 2025 am 12:33 AM

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
