PHP SoapFault not caught by exception handlers
提问by mrtsherman
I am new to PHP exception handling and SOAP. For some reason I cannot catch a SoapFault. I don't know why. The soap server is not mine.
我是 PHP 异常处理和 SOAP 的新手。出于某种原因，我无法捕获 SoapFault。我不知道为什么。肥皂服务器不是我的。
try {
$contact_id = $objSoapClient->getContactIdFromVisitorId('12345');
}
catch (SoapFault $sf) {
echo "Soapfault";
}
catch (Exception $e) {
echo "Exception";
}
I am purposely passing in the bad id 12345. When I enable errors I see the following message SoapFault exception: [SOAP-ENV:Client] Invalid Visitor ID. However, my catch SoapFault block nor my catch Exception block ever get hit. Why?
我故意传入错误 ID 12345。当我启用错误时，我看到以下消息SoapFault exception: [SOAP-ENV:Client] Invalid Visitor ID。但是，我的 catch SoapFault 块和我的 catch Exception 块都被击中。为什么？

The code you've submitted appears to be correct. Here's the only thing that comes to my mind.
您提交的代码似乎是正确的。这是我唯一想到的事情。
With that said, if the code is located inside a class that define a namespace, you code will not work as it will try to reference Exception as \namespace\Exception which does not exist. "Passive" references such as those in catchclauses or instanceofexpressions are permitted because the missing class could be loaded later.
话虽如此，如果代码位于定义命名空间的类中，您的代码将无法工作，因为它会尝试将 Exception 引用为不存在的 \namespace\Exception。允许“被动”引用，例如catch子句或instanceof表达式中的引用，因为可以稍后加载缺少的类。
For it to work, you have to prefix the class name with a slash (i.e. \Exception) to tell PHP to use PHP from the global space (or root if you want to call it that) (PHP) as opposed to your namespace;
为了让它工作，你必须在类名前加上一个斜杠（即\Exception）来告诉PHP使用全局空间中的PHP（或者root，如果你想调用它）（PHP）而不是你的命名空间；
<?php
namespace test;
class Foo
{
public function bar()
{
try
{
something_that_might_break();
}
catch (\Exception $e)
{
// this will work
}
}
}
?>
You can find lots of information about namespaces here: http://php.net/manual/en/language.namespaces.php.
你可以在这里找到很多关于命名空间的信息：http: //php.net/manual/en/language.namespaces.php。

The problem turned out to be my SoapClient declaration. There is an exceptions parameter that must be set in order for the exceptions to trigger.
问题原来是我的 SoapClient 声明。为了触发异常，必须设置一个异常参数。
$objSoapClient = new SoapClient('https://mywebservice.com/foo.wsdl', array(
"trace" => false,
"exceptions" => true, // <-------------- This!!!
'login' => 'username', //username
'password' => 'password', //password
'features' => SOAP_SINGLE_ELEMENT_ARRAYS + SOAP_USE_XSI_ARRAY_TYPE
));
