Code generation for the inventory alarm function in the PHP inventory management system

1. Requirements analysis
In the inventory management system, the inventory alarm function is very important. The system should be able to automatically send out alerts to notify administrators when inventory quantities fall below a set threshold. This article will explore how to code an inventory alert feature using PHP.

2. Code example

  1. Create database table
    First, we need to create a database table to store inventory information.
CREATE TABLE `inventory` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `product_name` varchar(50) NOT NULL,
  `quantity` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  1. Add inventory information
    Next, we need to add some sample inventory data to the database.
INSERT INTO `inventory` (`product_name`, `quantity`) VALUES
('商品A', 10),
('商品B', 5),
('商品C', 15);
  1. Create inventory alert function
    Now we start writing PHP code to implement the inventory alert function.
<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "your_password";
$dbname = "inventory_management";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取库存信息
$sql = "SELECT * FROM inventory";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $product_name = $row['product_name'];
        $quantity = $row['quantity'];

        // 检查库存数量是否低于阈值
        if ($quantity < 10) {
            sendAlert($product_name, $quantity);
        }
    }
} else {
    echo "暂无库存信息";
}

// 发送警报通知
function sendAlert($product_name, $quantity)
{
    // 根据实际需求实现发送警报的逻辑,可以是邮件、短信、推送等方式
    echo "商品{$product_name}的库存低于设定阈值,当前数量为{$quantity},请及时处理。";
}

// 关闭数据库连接
$conn->close();
?>

In the above sample code, we first connect to the database and then query the inventory information. For each inventory record, we check whether the inventory quantity is lower than the set threshold, and if so, call the sendAlert() function to send an alert notification.

4. Summary
Through the above code examples, we have successfully implemented the inventory alert function based on PHP. When the inventory quantity falls below the set threshold, the system will automatically send an alert notification to the administrator. You can extend this feature based on actual needs, such as adding more complex alert logic or choosing other ways to send notifications. I hope this article will help you understand and use PHP to write the inventory alert function in the inventory management system.
