I have an observer event tat right now grabs the customer info on customer_save_after at this point I am writing that information into a var log file.

I want to send that information to a SOAP API on an external web service.

Observer.php

    class Mage_Customerupdate_Model_Observer     {        public function logUpdate(Varien_Event_Observer $  observer) {     $  customer = $  observer->getEvent()->getCustomer();     $  name = $  customer->getName();     $  billingaddress = $  customer->getDefaultBillingAddress();     // just check if there is a billing adress     if ($  billingaddress) {         $  fon = $  billingaddress->getTelephone();         $  street1 = $  billingaddress->getStreet(1);         $  street2 = $  billingaddress->getStreet(2);         $  city = $  billingaddress->getCity();         $  region = $  billingaddress->getRegion();         $  postcode = $  billingaddress->getPostcode();      Mage::log("{$  name} {$  fon} {$  street1} {$  street2} {$  city} {$  region} {$  postcpde} updated", null, 'customerupdate.log', true);          }      }     } 

I have a wsdl url to send it to.

My variables there are:

    CustomerNumber (phone number)     CustomerName     CustomerAddress1     CustomerAddress2     CustomerCity     CustomerState     CustomerZip 

I am lost at how I can send the data to the SOAP client rather than to the var log.
