finally, you just need create a php page read everything through your class,here is the source code for one of the three shopping cart, for another two cart you just need to change the storeID, it make your job much easy.

the 3 order form just use the same class, you don’t to rewrite it, just change the storeID, you could use for any shopping cart.
the following post i will write the source code.
When you serialize an object with the serialize() function, PHP looks in the object’s class for a special function named __sleep() (with two leading underscores), which you can use to perform many of the same tasks as a destructor function. However, because a
destructor function is always called when a script that instantiates an object of a class ends,you do not need to duplicate any functionality between a destructor function and the __sleep() function. The primary reason for including a __sleep() function in a class is to specify which data members of the class to serialize. If you do not include a __sleep() function in your class, the serialize() function serializes all of its data members.
You don’t necessarily have to serialize every data member in a class, particularly for large objects that contain numerous data members. If you do include a __sleep() function in your class, the function must return an array of the data members to serialize or you will receive
an error.
Although the destructor function is always called, a constructor function is only called when you instantiate a new class object. This means that when you use the unserialize() function to restore a serialized class object, the constructor function does not execute. However,
when the unserialize() function executes, PHP looks in the object’s class for a special function named __wakeup() (with two leading underscore characters), which you can use to perform many of the same tasks as a constructor function. You use the __wakeup() function to perform any initialization the class requires when the object is restored. A typical use of the __wakeup() function is to initialize data members that were not saved with the serialization process, if there are any. Another use of the __wakeup() function is to restore any database or fi le connections that were lost during object serialization.
A destructor function is commonly called in two ways: when a script ends or when you manually
delete an object with the unset() function. You generally do not need to use a destructor function, although many programmers use one to close previously opened fi le handles and database connections. To add a destructor function to a PHP class, create a function named
__destruct() (with two leading underscore characters). Th e following code contains a destructor function that closes the database connection opened with the constructor function:
function __construct() {
$DBConnect = new mysqli(“php_db”, “dongosselin”,
“rosebud”, “real_estate”)
}
function __destruct() {
$DBConnect->close();
}
A constructor function is a special function that is called automatically when an object from a
class is instantiated. You defi ne and declare constructor functions the same way you defi ne other functions, although you do not include a return type because constructor functions do not return values. Each class defi nition can contain its own constructor function, named either __construct() (with two leading underscore characters) or the same name as the class.
