PHP development to build an enterprise resource planning (ERP) system with sales statistics function

With the expansion of enterprise scale and the complexity of business, the enterprise resource planning (Enterprise Resource Planning, ERP) system has become more and more important in enterprise management. played an important role. The ERP system can integrate the information flow of various departments of the enterprise and improve the efficiency and operational capabilities of the enterprise. Among them, the sales statistics function is an indispensable part of the ERP system. The sales statistics function can help enterprises understand the sales situation in real time and make reasonable decisions. This article will introduce how to use PHP to develop an ERP system with sales statistics function.

1. Design the database structure

Before developing the ERP system, you first need to design the database structure. According to the needs of sales statistics, the following data tables can be designed:

• Sales order table (sales_orders): stores relevant information of sales orders, such as order number, customer ID, sales date, etc.
• Sales order details table (sales_order_details): stores the specific product information of the sales order, such as product ID, quantity, unit price, etc.
• Product table (products): stores product-related information, such as product ID, name, specifications, etc.
• Customers table (customers): stores customer-related information, such as customer ID, name, contact information, etc.

2. Configuring the PHP development environment

Before proceeding with PHP development, you need to configure the PHP development environment. You can choose to build a PHP development environment locally, such as using an integrated development environment such as XAMPP or WAMP. You can also choose to deploy the development environment to a cloud server.

3. Database connection and data operation

In the PHP code, you first need to establish a connection with the database. You can use PDO (PHP Data Objects) extensions to implement database connections and data operations. The following is a sample code:

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { die('Database connection failed: ' . $e->getMessage()); } ?>

After establishing the connection, you can perform database data operations, such as insert, update, delete and query. The following is a sample code:

prepare($sql); $stmt->bindParam(1, $order_no); $stmt->bindParam(2, $customer_id); $stmt->bindParam(3, $order_date); $stmt->execute(); // 查询销售订单 $sql = "SELECT * FROM sales_orders"; $stmt = $pdo->prepare($sql); $stmt->execute(); $result = $stmt->fetchAll(PDO::FETCH_ASSOC); // 更新销售订单详情 $sql = "UPDATE sales_order_details SET quantity = ? WHERE order_id = ? AND product_id = ?"; $stmt = $pdo->prepare($sql); $stmt->bindParam(1, $quantity); $stmt->bindParam(2, $order_id); $stmt->bindParam(3, $product_id); $stmt->execute(); // 删除销售订单 $sql = "DELETE FROM sales_orders WHERE order_id = ?"; $stmt = $pdo->prepare($sql); $stmt->bindParam(1, $order_id); $stmt->execute(); ?>

4. Implementing the sales statistics function

After the database connection and data operations have been completed, you can start to implement the sales statistics function. According to specific needs, the following functions can be implemented:

• Statistics of monthly sales: This can be achieved by querying the sales order table and grouping by month.

prepare($sql); $stmt->bindParam(1, $start_date); $stmt->bindParam(2, $end_date); $stmt->execute(); $result = $stmt->fetchAll(PDO::FETCH_ASSOC); ?>

• Statistics of each customer's sales: This can be achieved by querying the sales order table and associating the order with the customer table.

prepare($sql); $stmt->bindParam(1, $start_date); $stmt->bindParam(2, $end_date); $stmt->execute(); $result = $stmt->fetchAll(PDO::FETCH_ASSOC); ?>

• Count the sales quantity of each product: This can be achieved by querying the sales order details table and associating the order details with the product table.

prepare($sql); $stmt->bindParam(1, $start_date); $stmt->bindParam(2, $end_date); $stmt->execute(); $result = $stmt->fetchAll(PDO::FETCH_ASSOC); ?>

Through the above sample code, we can implement an ERP system with sales statistics function. Of course, it can be further expanded and optimized according to specific needs, such as adding filtering conditions, chart display, etc.

Summary:

This article introduces how to use PHP to develop an ERP system with sales statistics function, including database structure design, PHP development environment configuration, database connection and data operation, and implementation of sales statistics function Related code examples. I hope it will be helpful to developers who are developing ERP systems and can promote the improvement and optimization of enterprise sales management.
