How to use PHP Developer City to realize product inventory alarm email reminder

With the rapid development of e-commerce, the management of online malls has become more and more important. Among them, product inventory management is an important link, related to whether merchants can meet user needs in a timely manner. In order to better manage inventory, you can use PHP Developer City to implement product inventory alarm email reminder functions. This article will introduce how to use PHP to develop the city and implement inventory alarm email reminders by writing code.

1. Preparation work
Before you start writing code, you need to ensure that you have set up a PHP development environment with a MySQL database and SMTP mail server.

2. Database design
First, we need to create a database to store product information and inventory data. Create a database named "shop" and create two tables "products" and "stock" in it.

1. The table "products" is used to store basic information of products, including id, product name, price, etc. The table structure is as follows:
CREATE TABLE products (
id int(11) NOT NULL AUTO_INCREMENT,
name varchar(255) NOT NULL,
price decimal(10,2) NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

2. Table "stock" is used to store inventory information of products, including product ID, inventory quantity, etc. The table structure is as follows:
CREATE TABLE stock (
id int(11) NOT NULL AUTO_INCREMENT,
product_id int(11) NOT NULL,
quantity int(11) NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

3. PHP code writing
Next, we will write PHP code to implement the product inventory alarm email reminder function. First, connect to the database and obtain product information whose inventory is lower than the set value.

1. Connect to the database:
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "shop";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {

die("连接失败: " . $conn->connect_error);

}

2. Obtain product information whose inventory is lower than the set value:
$low_stock_quantity = 10; // Set the inventory alarm quantity
$sql = "SELECT products.name, stock .quantity FROM products JOIN stock ON products.id = stock.product_id WHERE stock.quantity < $low_stock_quantity";
$result = $conn->query($sql);

3.Send Email reminder:
if ($result->num_rows > 0) {

require_once 'PHPMailer/PHPMailerAutoload.php'; // 导入PHPMailer类

$mail = new PHPMailer();
$mail->isSMTP();
$mail->SMTPAuth = true;
$mail->Host = "smtp.gmail.com"; // 设置SMTP服务器
$mail->Username = "your_email@gmail.com"; // 发件人邮箱
$mail->Password = "your_password"; // 发件人邮箱密码
$mail->SMTPSecure = "ssl";
$mail->Port = 465;

$mail->setFrom("your_email@gmail.com", "E-commerce Shop");
$mail->addAddress("recipient_email@example.com"); // 收件人邮箱
$mail->isHTML(true);
$mail->Subject = "商品库存报警";
$mail->Body = "以下商品库存低于设定值：

";

while ($row = $result->fetch_assoc()) {
    $mail->Body .= "商品名称：" . $row["name"] . "，当前库存：" . $row["quantity"] . "

";

}

if ($mail->send()) {
    echo "邮件发送成功";
} else {
    echo "邮件发送失败：" . $mail->ErrorInfo;
}

}

4. Implement scheduled tasks
In order to regularly check product inventory and send email reminders, you can use cronjob (Linux) or Task Scheduler (Windows) to implement scheduled tasks. Set a daily task and run the above PHP script at the specified time.

To sum up, by setting up a PHP development environment, designing the database structure, writing PHP code, and setting up scheduled tasks, we can realize the product inventory alarm email reminder function. In this way, merchants can monitor inventory status in a timely manner and take timely replenishment measures to improve user satisfaction and sales efficiency.
