NuSoap vs PHP Soap Library. Where is getError?

Question

I'm converting an old code which use NuSoap to PHP Soap Library. But method getError in NuSoap PHP seems not exist in PHP Soap Libary and I get this error:

Fatal error: Uncaught SoapFault exception: 
[Client] Function ("getError") is not a valid method for this service in index.php:33
Stack trace: #0 index.php(33): SoapClient->__call('getError', Array) #1 index.php(33):
SoapClient->getError() #2 index.php(63): pay() #3 {main} thrown in /homeindex.php on line 33 

Here is my code:

<?php
    $client = new SoapClient('my soap server');
    $err = $client->getError();
?>

How I supposed to get error in PHP Soap library?

Answer 1

<?php
    $client = new SoapClient('my soap server');
    $err = $client->soapCall($somfunctioname,$arrofargs );

?>

If there is any error It with the soapCall .It returns a instance of SoapFault() where you can log the errorcode, description so.. on
