$options = array(
'uri' => 'http://aahshhs.com',   //wath do this line?????
'location' => 'http://localhost/exer/Server.php',);

Answer 1

An array of options. If working in WSDL mode, this parameter is optional. If working in non-WSDL mode, the location and uri options must be set, where:

• location is the URL of the SOAP server to send the request to
• uri is the target namespace of the SOAP service.
