If you’re doing something with webservices and PHP, you’ll most likely use the NuSOAP library. However this may be a problem when you’ve upgraded your PHP installation to version 5 or better. Since this version PHP has a built in soap client which uses the same name as the NuSOAP class, you can still use NuSOAP but you need to make two changes, namely rename the class “soapclient” and its constructor to, for example, “soap_client”. Remember to fix this in all your other code too!
