有人能帮我找出这出了什么问题吗

使用

print_r（）通常不会提供任何有用的内容。相反，您应该使用输出原始XML的asXML（）

$xml = simplexml_load_string($responseXML);
echo $xml->asXML();

给
<?xml version="1.0" encoding="UTF-8"?>
<soap-env:envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:header>
      <soap-env:body>
...

因此，$bodyData
是
元素，因此使用最后一行访问该元素的每个部分。您可以使用元素名（减去名称空间前缀ipgapi，因为前面的children（）
调用会处理这个问题）。那条线输出

双引号和单引号。基本的东西，看看代码highlighting@RiggsFolly-抱歉，我的错误，我按submit而没有修复单引号：此函数可能返回布尔值FALSE，但也可能返回计算结果为FALSE的非布尔值。有关更多信息，请阅读布尔值部分。使用===运算符测试此函数的返回值。那么如何获取XML中的各个值呢？您好，访问数据不是这样工作的。不过，$xml->asXML（）的第一个示例仍然有效。
<?xml version="1.0" encoding="UTF-8"?>
<soap-env:envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:header>
      <soap-env:body>
...

$xml = simplexml_load_string($responseXML);
$body = $xml->xpath("//soap-env:body");
$bodyData = $body[0]->children("ipgapi", true);
echo $bodyData->ipgapiorderresponse->approvalcode;
