不明确的PHP Web服务错误消息

did anyone ever encounter the following error message

Extra content at the end of the document

when trying to consume a PHP web service from a client that runs on php 5.3?

I guess soembody did. ^^

Anyways, I don't seem to find an error in the server code which works for several clients of mine for quite some time now. Is this possibly a php problem in the recent version?

My client code looks like this:

try
{
  $client = new SoapClient("http://someserver/server.php?wsdl", array('trace' => 1, 'feature' => SOAP_SINGLE_ELEMENT_ARRAYS));
}   
catch(Exception $e)
{$this->handleException($e);}

Any thoughts on this would be highly appreciated.

TIA

Sounds like the XML is not well formatted. Is the WSDL generated or created manually?
