Soap - Php5 - Help

[liunx]

I have to post 3 strings to a soap server.
username, password and content

Whatever I trie, I always get a blank screen and no response.

Look at this (from soapclient.com)

<!-- m --><a class="postlink" href="http://www.edv-weidacher.de/articleimport.jpg">http://www.edv-weidacher.de/articleimport.jpg</a><!-- m -->

This is one of the code I used.
I tried several snippets I found on the web but with no luck.
------------------------------------------------------------------------------

$client = new SoapClient("...../importarticles.cfc?wsdl", array('trace' => 1));
$param=array(
'username'=>'nobody',
'password'=>'anonymous',
'content'=> $xml
);
echo $client->call('articleimport', $param);


I appreciate any help

Thanks a lot
