Can we call a webservice and get the authentication done without passing the credentials(username and password) through the url.

For eg:

$client = new soapclient2('https://username:password@/SampleService?wsdl', true,$proxyhost,$proxyport,$proxyusername,$proxypassword,0,30);

In this call the username and password are sent along with the wsdl url.I dont want it that way.Is there some other means to acheive the same?


Thanks,
LJoy.
