Ipmonitor 10.0, Soap and PHP 5

Hello

I am a newbie with soap on php.

Can someone give me a sample script to get monitor status from ipmonitor with soap and php5 ?

I tried this but I  always have an error "401 access denied":

$ Client = new  SoapClient ("http://localhost:8080/soap/status.asmx?wsdl", array  ('login' => "user", 'password' => "password"));


Thank you for your help
