Inventory transfer statistics is a very important function in the inventory management system. It can help administrators track and manage different warehouses. Inventory transfer status between periods. In this article, we will introduce how to use PHP to write a simple inventory transfer statistics function and provide corresponding code examples.

First, we need to create a database table to store inventory transfer records. The table needs to contain the following fields: allocation record ID (allocation_id), product ID (product_id), warehouse ID (warehouse_id), allocation time (allocation_date), and allocation quantity (allocation_quantity).

CREATE TABLE allocations (
    allocation_id INT PRIMARY KEY AUTO_INCREMENT,
    product_id INT NOT NULL,
    warehouse_id INT NOT NULL,
    allocation_date DATE NOT NULL,
    allocation_quantity INT NOT NULL
);

Next, we need to create a page in the system to display inventory transfer statistics. First, we need to connect to the database.

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

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

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

In the page, we can add a table to display inventory transfer statistics.

<html>
<head>
    <title>库存调拨统计</title>
</head>
<body>
    <h1>库存调拨统计</h1>
    <table>
        <tr>
            <th>调拨记录ID</th>
            <th>商品ID</th>
            <th>仓库ID</th>
            <th>调拨时间</th>
            <th>调拨数量</th>
        </tr>
        <?php
        $sql = "SELECT * FROM allocations";
        $result = $conn->query($sql);

        if ($result->num_rows > 0) {
            // 输出数据
            while($row = $result->fetch_assoc()) {
                echo "<tr>";
                echo "<td>" . $row["allocation_id"] . "</td>";
                echo "<td>" . $row["product_id"] . "</td>";
                echo "<td>" . $row["warehouse_id"] . "</td>";
                echo "<td>" . $row["allocation_date"] . "</td>";
                echo "<td>" . $row["allocation_quantity"] . "</td>";
                echo "</tr>";
            }
        } else {
            echo "没有库存调拨记录";
        }
        ?>
    </table>
</body>
</html>

The above code will read the inventory transfer records from the database and display them on the page in table form. Please make sure to save the above code as a PHP file and place the file on your server to run.

Through the above code example, we can simply implement a PHP-based inventory transfer statistics function. You can modify and extend this example according to your actual needs. Hope this article helps you!
