自定义类型元素键的数组

Question

我正在尝试从PHP获得像这样的多维对象数组的响应

[CartItems] => Array
(
    [15] => stdClass Object
    (
        [key] => 15
        [value] => stdClass Object
        (
            [Item] => stdClass Object
            (
                [id] => 1
                [quantity] => 7
            )
        )
    )
    [25] => stdClass Object
    (
        [key] => 25
        [value] => stdClass Object
        (
            [Item] => stdClass Object
            (
                [id] => 1
                [quantity] => 5
            )
        )
    )
    [26] => stdClass Object
    (
        [key] => 26
        [value] => stdClass Object
        (
            [Item] => stdClass Object
            (
                [id] => 1
                [quantity] => 5
            )
        )
    )
)

我在WSDL文件中尝试了一种Array类型

<xsd:complexType name="ArrayOfProducts">
                    <xsd:complexContent>
                        <xsd:restriction base="soapenc:Array">
                            <xsd:attribute ref="soapenc:arrayType" wsdl:arrayType="Product[]"/>
                        </xsd:restriction>
                    </xsd:complexContent>
                </xsd:complexType>

这里的要点是我想使用键直接返回带有可访问元素的数组'CartItems'

我不特别依赖这个解决方案，我只是想直接访问每个对象，而无需遍历所有数组以找到所需的对象。
