Creating a Web Reference to WSDL in PHP

[SurgeProto]

I have some code that I'm converting from VB into PHP that refers to the a class called Outbound. I was told Outbound is merely a reference to a WSDL (for example [a href=\"http://www.mydomain.com/mywsdl.wsdl)\" target=\"_blank\"]http://www.mydomain.com/mywsdl.wsdl)[/a]. How can I create this reference in PHP so I can use this class?

Also, as a bonus, once I have access to it, how can I translate the following vb code into PHP:


Dim CallItemObject As New Outbound.CallItem
CallItemObject.siteNumber = SiteNumber

Dim WebServiceCall As New Outbound.OutboundCallService
placecallresponse = WebServiceCall.placeCall(placecallobject)


ANY help on this would be tremendously appreciated.
