What exactly happens when I call a web service method using PHP::SOAP?

Say I have a simple client/server scenario with one method:

// client code
$client = new SoapCLient("service.wsdl");
$result = $client.getPi();

...

// server code
function getPi(){
   return 3.141;
}
$server = new SoapServer("service.wsdl");
$server.addFunction("getPi");
$server.handle();

Am I right in thinking that when the client makes a call to the getPi() method the addfunction() gets called everytime? Is this really how PHP SOAP web services work? Or is there some caching going on?

Thanks.
