"new SoapClient()"的 PHP 不是那么致命的错误

Question

我有这个片段运行:

foreach($config as $wsInfo){
  try{
    $soapClient = new SoapClient($wsInfo['url'], 
                                 array('encoding'=>'ISO-8859-1'));

    //  Some more code that I commented out.

  }
  catch(Exception $e){
    echo "EXCEPTION: \n" . $e->getMessage();
    // log it, etc.
  }
}

当我运行该程序时，Web 服务 URL 会以身份验证错误响应我(在开发阶段这是可以的)。

我注意到的异常行为是，虽然我对此有所期待:

$ php scan.php -p=/ -c=config.yml
EXCEPTION: 
SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://webservices.myserver.com/api.asmx?WSDL' : failed to load external entity "http://webservices.myserver.com/api.asmx?WSDL"
EXCEPTION: 
SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://webservices.myserver.com/api.asmx?WSDL' : failed to load external entity "http://webservices.myserver.com/api.asmx?WSDL"

它给了我这个:

$ php scan.php -p=/ -c=config.yml
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://webservices.myserver.com/api.asmx?WSDL' : failed to load external entity "http://webservices.myserver.com/api.asmx?WSDL"
 in /home/me/project/DFPushSOAP.php on line 34

为什么“PHP fatal error ”没有杀死程序？为什么它会逃避 try/catch block ？

我怎样才能避免这种情况？

我遇到了同样的问题，并在 https://bugs.php.net/bug.php?id=47584 找到了解决方案.

首先你应该设置exceptions强制 SoapClient 抛出异常的选项:

    $soapClient = new SoapClient($wsInfo['url'], array('encoding'=>'ISO-8859-1'
                                                       'exceptions' => true ));

在我的情况下，xdebug 强制产生 fatal error 而不是可捕获的异常。
因此，您应该尝试为 SoapClient 创建禁用 xdebug:

    if(function_exists('xdebug_disable')){ xdebug_disable(); };
    $soapClient = new SoapClient($wsInfo['url'], array('encoding'=>'ISO-8859-1'
                                                       'exceptions' => true ));
    if(function_exists('xdebug_enable')){ xdebug_enable(); };

希望这对你有帮助^^
