How to use PHP to develop automated product inventory management tools
Commodity inventory management is one of the daily tasks that every enterprise must face, and it is developed using PHP Automated merchandise inventory management tools can greatly improve the efficiency and accuracy of your business. This article will introduce how to use PHP to develop a simple and practical automated product inventory management tool, and come with code samples for reference.
1. Requirements Analysis
Before we start writing code, we first need to conduct a needs analysis to clarify our goals and functional requirements. A basic product inventory management tool should have the following functions:
2. Database design
Based on the above requirements, we need to design the database and create corresponding data tables. Here we create a database named "inventory_management", which contains two data tables: product table (products) and sales record table (sales).
Product table (products)
Sales record table (sales)
3. Code implementation
<?php $host = "localhost"; $dbname = "inventory_management"; $username = "root"; $password = ""; $pdo = new PDO("mysql:host=$host;dbname=$dbname;charset=utf8", $username, $password); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
<?php // 添加商品 function addProduct($name, $price, $quantity) { global $pdo; $stmt = $pdo->prepare("INSERT INTO products (name, price, quantity) VALUES (?, ?, ?)"); $stmt->execute([$name, $price, $quantity]); return $pdo->lastInsertId(); } // 修改商品信息 function updateProduct($id, $name, $price, $quantity) { global $pdo; $stmt = $pdo->prepare("UPDATE products SET name = ?, price = ?, quantity = ? WHERE id = ?"); $stmt->execute([$name, $price, $quantity, $id]); return $stmt->rowCount(); } // 删除商品 function deleteProduct($id) { global $pdo; $stmt = $pdo->prepare("DELETE FROM products WHERE id = ?"); $stmt->execute([$id]); return $stmt->rowCount(); }
<?php // 更新库存数量 function updateQuantity($id, $quantity) { global $pdo; $stmt = $pdo->prepare("UPDATE products SET quantity = ? WHERE id = ?"); $stmt->execute([$quantity, $id]); return $stmt->rowCount(); }
<?php // 添加销售记录 function addSale($productId, $quantity, $saleDate) { global $pdo; $stmt = $pdo->prepare("INSERT INTO sales (product_id, quantity, sale_date) VALUES (?, ?, ?)"); $stmt->execute([$productId, $quantity, $saleDate]); return $pdo->lastInsertId(); }
slightly.
Omitted.
4. Summary
Through the above code examples, we can see that it is not difficult to develop automated product inventory management tools using PHP. This simple and practical tool can not only improve the efficiency and accuracy of enterprises, but also provide various statistical reports to help enterprises conduct sales statistics and forecasts. Of course, this is just a basic example, and actual applications need to be expanded and optimized according to specific business needs.
