在try-catch中从Object内部的Array获取内容 - Get content from Array inside Object in a try-catch

Get content from Array inside Object in a try-catch

目前，我正在使用try-catch来确定web服务是否可调用:

try {
  WebServices::create($this->nameWS);
}
catch (Exception $e) {                      
  var_dump($e);     
}

现在，$e包含错误消息以及一个包含数组的对象，如下所示。

注意:看似随机的"在第三行以下和接近末尾。

我相信你可以看到我想要得到的字符串-这是我在代码中留下的唯一一个- "GetMeService"(它在[3]中的["class"]=>内)

object(SoapFault)#304 (8) {
  ["message:protected"]=>
  string(182) "SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://localhost:8080/examplewsdl' : failed to load external entity "http://localhost:8080/examplewsdl"

  ["faultcode"]=>
  string(4) "WSDL"
}

无论我尝试用(例如var_dump($e=>["trace:private"][3]["class"]);)替换我的var_dump，我都无法访问该字符串。这可能吗?

参见文档
SoapFault类有很好的文档记录。
有很多方法。
要访问跟踪，请使用getTrace()方法。

http://php.net/manual/en/class.soapfault.php

试题:

try {
  WebServices::create($this->nameWS);
}
catch (Exception $e) {                      
  $tr = $e->getTrace();
  var_dump($tr[3]);     
}
