Recipe 15.4. Generating WSDL Automatically

15.4.1. Problem

You want to expose a set of methods via a SOAP web service. You want to automatically generate a WSDL file that describes this service.

15.4.2. Solution

The ext/soap extension does not support WSDL generation. However, there are a few other PHP scripts that you can use.

15.4.3. Discussion

Given the nature of SOAP, it's vital to provide clients with a WSDL file they can use to configure themselves for your server. Unfortunately, ext/soap does not support WSDL generation.

Therefore, you must either generate WSDL by hand from scratch, modify an existing document that supports a similar set of operations, or use an unofficial script, such as:

WSDL_Gen, by George Schlossnagle

wsdl-writer, by Katy Coe based on code by David Griffin

Web service helper, by David Kingma

None of these scripts supports the entire SOAP and WSDL specifications, and each one uses a slightly different syntax to accomplish its goal. You should investigate all of them to see if they do what you need and fit your programming styles.
