Design ideas for mall inventory management system developed with PHP

1. Introduction
With the rapid development of e-commerce, mall inventory management has become an important issue. In order to help merchants better manage product inventory and improve inventory utilization and sales efficiency, we can develop a mall inventory management system implemented in PHP language. This article mainly introduces the design ideas of the system and attaches code examples.

2. System requirements analysis
The mall inventory management system needs to have the following functions:
1. Product information management: including adding, modifying, deleting and querying products.
2. Inventory management: including inventory increase, decrease and inquiry.
3. Order management: including order creation, cancellation and inquiry.
4. Data statistics and reports: including statistics and report generation of sales, inventory quantity and other data.

3. System design
1. Database design
The database of the system uses MySQL, and the following tables are designed:

• Product table (product): contains product ID , name, price and other fields.
• Inventory table (inventory): Contains fields such as product ID, inventory quantity, etc.
• Order table (order): contains fields such as order ID, product ID, purchase quantity, etc.

2. Front-end page design
The front-end page of the system is implemented using HTML, CSS and JavaScript, and adopts a responsive layout to adapt to the display of different devices.

3. Back-end logic design
The back-end of the system is mainly implemented using PHP language and designed using object-oriented programming ideas. Here is a code example:

class Product {
private $id;
private $name;
private $price;

public function __construct($id, $name, $price) {

}
}

// Example usage
$product = new Product(1, 'Product A', 10);
$inventory = new Inventory($product, 100);
$order = new Order(1, $product, 5);

echo $product->getName(); // Output: Product A
echo $inventory->getQuantity(); // Output: 100
echo $order-> ;getQuantity(); // Output: 5

$inventory->increaseQuantity(50);
echo $inventory->getQuantity(); // Output: 150

$inventory->decreaseQuantity(200);
echo $inventory->getQuantity(); // Output: 150 (insufficient inventory, no inventory reduction)

$inventory->decreaseQuantity(100 );
echo $inventory->getQuantity(); // Output: 50

?>
