如何通过PHP从这个对象中检索属性？

Question

我有一个从Expedia API响应的对象。

[Surcharges] => stdClass Object
(
    [@size] => 1
    [Surcharge] => stdClass Object
        (
            [@type] => TaxAndServiceFee
            [@amount] => 9.59
        )

)

如何检索@typevà@ amount属性。

我尝试了宽度Surcharges->Surcharge->type或Surcharges->Surcharge->@type，但没有成功

Answer 1

尝试使用

Surcharges->Surcharge->{"@type"}

Answer 2

尝试

Surcharges->Surcharge->{"@type"}
