I've build a webservice in php using nuSoap, and now I need to use wsdl to publish my services
There's a method to convert php in wsdl file? 
php -> wsdl convertion is possible?

I know this is an old post.. but wanted to put this out here in case others search for these keywords.
I created a wsdl generator for php based webservices. Its really basic, written in a day, but I hope to expand it with feedback and use.
Its windows based.. sorry to the rest of you.. but it works for me for the basic soap servers in php that I have created.
