This article will give a detailed introduction on how to use the PHP Developer City to implement the function of putting products on and off the shelves.

1. Mall database design
   Before developing the product listing and removal functions, you first need to design the mall database. Common product database tables include product tables, classification tables, brand tables and product association tables.

Add a field to the product table to record the status of the product, for example, use a field named "status", 1 means on the shelf, 0 means off the shelf.

In the PHP code, you can determine what label to display by judging the value of the product status field. For example, use the following code:

上架";
} else {
    echo "下架";
}
?>

Through the above steps, you can use the PHP Developer City to implement the function of putting products on and off the shelves. . Of course, other details need to be taken into consideration in actual development, such as permission management, product inventory, etc. But the above steps can provide developers with a basic guide.
