PHP development of enterprise resource planning (ERP) system to build sales statistical report function

With the rapid development of the Internet, enterprises are facing more and more challenges in the management and operation process. In order to better manage corporate resources and improve operational efficiency, many companies have begun to adopt enterprise resource planning (ERP) systems. The ERP system achieves unified management of enterprise resources by integrating information and processes from various departments.

In the ERP system, sales statistical reports are a very important function. It can help companies understand sales, analyze sales trends, and make decisions based on these analysis results. Building an ERP system with sales statistics report function requires the use of a powerful and flexible development language, and PHP is a good choice.

Let's demonstrate how to use PHP to develop a simple sales statistics report function.

First, we need to create a database to store sales data. Suppose we have a sales table that contains the following fields: id (sales ID), product (product name), quantity (sales quantity), price (sales price), and date (sales date).

CREATE TABLE sales (
    id INT AUTO_INCREMENT PRIMARY KEY,
    product VARCHAR(100),
    quantity INT,
    price DECIMAL(10, 2),
    date DATE
);

According to this table structure, we can write PHP code to insert sales data into the database. The following is a simple example:

connect_error) {
    die("连接失败：" . $conn->connect_error);
}

$sql = "INSERT INTO sales (product, quantity, price, date) VALUES
('Product 1', 10, 100, '2021-01-01'),
('Product 2', 5, 200, '2021-02-01'),
('Product 3', 8, 150, '2021-03-01')";

if ($conn->query($sql) === TRUE) {
    echo "数据插入成功";
} else {
    echo "数据插入失败：" . $conn->error;
}

$conn->close();
?>

Next, we need to write PHP code to generate sales statistics reports. The following is a simple example:

connect_error) {
    die("连接失败：" . $conn->connect_error);
}

$sql = "SELECT product, SUM(quantity*price) AS total_sales FROM sales
        GROUP BY product";

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    echo "";
    echo "";

    while ($row = $result->fetch_assoc()) {
        echo "";
    }

    echo "
产品
销售额
" . $row["product"] . "
" . $row["total_sales"] . "
";
} else {
    echo "没有数据";
}

$conn->close();
?>

The above code queries the sales data in the database, calculates the total sales of each product, and displays the results in table form.

Of course, the actual sales statistics report may require more complex analysis and display. We can use more SQL statements and PHP code to complete more functions according to specific needs.

To sum up, PHP is an enterprise resource planning (ERP) system development language that is very suitable for developing sales statistical report functions. By using PHP, we can easily extract sales data from the database and perform various complex analyzes and calculations. I hope this article can help you better understand how to use PHP to develop an enterprise resource planning (ERP) system with sales statistical reporting functions.
