如何解析异常错误

我正在用肥皂工作。当我调用时，我使用try {} catch{}块。我想保存异常错误到数据库中。为了美化代码，我将错误解析到另一个函数中，示例如下:

$paramis = array(
                'client' => '225',
                'film_id' => '612',
                'booking' => '2016-02-28',
                'persons' => 1
            );
$puri = 'http://www.filmonschedule.com/Portal/break.asmx?WSDL';
$client = new SoapClient($puri, array('trace' => 1, 'exceptions' => 1));
//var_dump($client);
try {
    $resp = $client->__soapCall('getFilmToBook', array('parameters' => $paramis));
} catch (Exception $e) {
    printErrorMu($e);
}
function printErrorMu($e)
{
    print_r($e);
}

这是输出prininterrormu ($e)

        (
            [exceptionInfo] => No schedule for this booking request
        )
)

，但我不能读取参数作为对象/数组内的函数printErrorMu($e)。如何将参数转换为数组或对象，以便我可以访问属性/键的这些值([message:protected][string:Exception:private][code:protected][file:protected][line:protected][trace:Exception:private][previous:Exception:private]) ?

谢谢。
