How to use PHP to write the inventory turnover rate analysis function code in the inventory management system

The inventory turnover rate refers to the amount of goods in the inventory that the company has sold during a certain period of time and the number of replacements. It is an important indicator to evaluate the effectiveness of enterprise inventory management. Implementing the inventory turnover rate analysis function in the inventory management system can help enterprises better understand inventory operations and take timely adjustment measures. Improving inventory turnover rate has an important impact on the profitability of enterprises.

This article will use PHP as the development language and introduce how to use PHP to write the inventory turnover rate analysis function code in the inventory management system. The following uses an example to demonstrate the specific implementation process.

First, we need to prepare a database table containing product information, such as a table named products. 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,
  `quantity` int(11) NOT NULL,
  `sold_quantity` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Next, connect to the database in the PHP code and query the data required for inventory turnover rate analysis. The code is as follows:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// 查询库存信息
$sql = "SELECT SUM(quantity) AS total_quantity, SUM(sold_quantity) AS total_sold_quantity FROM products";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $totalQuantity = $row["total_quantity"];
        $totalSoldQuantity = $row["total_sold_quantity"];
    }
} else {
    echo "没有数据";
}

// 计算库存周转率
$inventoryTurnoverRatio = $totalSoldQuantity / $totalQuantity;

echo "库存周转率: " . $inventoryTurnoverRatio;

// 关闭连接
$conn->close();

Through the above code, we can get the total quantity in inventory and the total quantity sold, and then calculate the inventory turnover rate. Finally, the results are output to the user.

In practical applications, we can expand the code according to needs and add more query conditions, such as inventory turnover rate analysis according to product categories and time periods. The results can also be displayed and analyzed graphically to increase user experience and usage value.

The above is an example of using PHP to write the inventory turnover rate analysis function code in the inventory management system. I hope this article can help you understand how to implement the inventory turnover rate analysis function. Through this function, companies can better adjust inventory strategies and improve operational efficiency and product sales capabilities.
