Design analysis of automatic confirmation of receipt of shopping mall orders developed by PHP

Analysis of the automatic confirmation and receipt design of mall orders developed by PHP

1. Background introduction
With the rapid development of the e-commerce industry, more and more mall websites have appeared one after another. For shopping malls, order confirmation and receipt is a key link. In order to improve user experience and reduce manual operation costs, malls often design functions to automatically confirm receipt of orders. This article will analyze in detail the design of automatic receipt confirmation for mall orders developed in PHP and provide corresponding code examples.

2. Functional design ideas
The design idea of ​​automatic order confirmation of receipt is mainly divided into the following steps:

1. Order status monitoring: The status of the order needs to be monitored in real time. When the order status is shipped and the delivery confirmation time exceeds a certain time, the order status is automatically changed to completed.
2. Scheduled task triggering: In order to realize the function of automatically confirming receipt, you can use scheduled tasks to trigger. Scheduled tasks can regularly perform operations to check the order status.
3. Configuration parameter settings: In order to facilitate the mall administrator to control the rules for automatic confirmation of receipt of orders, corresponding configuration parameters can be provided, such as the time interval for automatic confirmation of receipt, etc.
4. Database operation: Database operation is required to update the order status.
5. Email notification: After the order is automatically confirmed to be received, an email notification can be sent to the user to inform the user that the order has been completed.

3. Code Example
The following is a simple PHP code example, used to realize the function of automatically confirming the receipt of orders:

1. Configuration file config.php

<?php
return [
    'confirm_hours' => 72, // 自动确认收货时间间隔，单位为小时
];
?>

2. Order confirmation and receipt script confirm.php

<?php
$config = include 'config.php';

$now = time();
$confirmHours = $config['confirm_hours'];
$confirmTime = $now - ($confirmHours * 3600);

// 查询需要自动确认收货的订单
$sql = "SELECT * FROM orders WHERE status = '已发货' AND confirm_time <= {$confirmTime}";
$result = mysqli_query($conn, $sql);

while ($row = mysqli_fetch_assoc($result)) {
    $orderId = $row['id'];

    // 更新订单状态为已完成
    $updateSql = "UPDATE orders SET status = '已完成' WHERE id = {$orderId}";
    mysqli_query($conn, $updateSql);

    // 发送邮件通知用户
    $userId = $row['user_id'];
    $userEmail = getUserEmailById($userId); // 根据用户ID查询用户邮箱
    sendEmail($userEmail, '订单已完成', '您的订单已完成，请查收！');
}
?>

IV. Summary
This article mainly introduces the automatic confirmation and receipt of mall orders developed by PHP design ideas and provide corresponding code examples. Through functions such as real-time monitoring of order status, scheduled task triggering, database operations, and email notifications, the function of automatically confirming the receipt of orders can be realized, improving user experience and reducing manual operation costs. Readers can make corresponding modifications and additions according to actual needs to adapt it to their own mall system.
