我试图在PHP中编写购物车,我在多维数组中有get/set值的问题.我保持当前的订单$_SESSION['basket'].它看起来像这样:

[basket] => Array
        (
            [0] => Array
                (
                    [pid] => 3
                    [name] => Camera
                    [price] => 200.99
                    [quantity] => 1

                )

            [1] => Array
                (
                    [pid] => 5
                    [name] => Computer
                    [price] => 320.99
                    [quantity] => 1

                    [extras] => Array
                        (
                            [0] => Array
                                (
                                    [pid] => 86
                                    [name] => RAM
                                    [price] => 99
                                    [qty] => 1
                                )

                            [1] => Array
                                (
                                    [pid] => 98
                                    [name] => CD-ROM
                                    [price] => 19.99
                                    [qty] => 1
                                )

                        )

                ) …
