webservices in PHP
 

Hi
Can anyone give me some good samples/reference links to create a webservice in PHP.
My search in Google ends up with some outdated web pages.
The sites i followed gives a lot of warnings saying that call - time-pass- by reference has been deprecated.

Actually i want to do it with Zend framework
but thinking to do it first with normal PHP and then use the framework components..

Please help
Regards
