我在处理订单here时看到了Google Checkout的XML响应。
我还看过google responsehandlerdemo.php文件，我在下面复制过。
我无法弄清楚我应该在哪里插入我将用来更新我店铺库存水平的代码。有人能指点我吗？我也不太确定如何在收到一份respohnse时找出订购的内容。

我假设我想在下面的块中执行此操作，但我真的根本不确定如何解析XML，这是我之前从未使用过的PHP。

答案 0 :(得分：1)
答案 1 :(得分：1)
好像你走在正确的轨道上：你想要在收到订单时减少库存，所以如果你的库存变为零，你可以在其他地方立即显示该商品缺货。
至于你的另一个问题，看起来$ data [$ root]数组的每个括号级别都会让你进入XML结构中的另一个级别，就像你的示例代码的商家回调计算一样。
整个回复似乎都在$ data中，所以我只看一下示例响应，然后四处寻找你正在寻找的东西。也许使用一些echo语句来看看在不同的地方出现了什么['VALUE']。
完全是启发式答案，但希望它有所帮助。 ;）
答案 2 :(得分：0)
John说，但确认答案是$ data是关键。
例如，订单号是可以使用以下内容回显的值：
$数据[$根] [ '谷歌阶数'] [ 'VALUE']
......等等。
