使用PEAR Soap模拟php_soap

I have Magento installed and would like to start using the API, however the Magento API uses Zend (Zend_Soap_Server) for Soap which relies on php_soap.

My provider does not (and refuses to) support php_soap, but does support PEAR soap and it is working properly (I have other web services operating successfully with PEAR soap).

So, is anyone aware of an already-written library that I could include to emulate php_soap using PEAR SOAP_Server?

class SoapServer{
    ...
    //Functions from http://php.net/manual/en/class.soapserver.php 
    // re-written to use functions from https://pear.php.net/reference/SOAP-0.9.1/SOAP/SOAP_Server.html

}

There are other posts on SO where others have experienced similar challenges, except installing php_soap is not an option and I'd prefer not to change providers over this alone:

• Enable Pear SOAP module on shared platform

You'd have to write a 1:1 identical SoapClient implementation in PHP userland code, which is possible but quite a task.

You might use PEAR's SOAP_Server as backend, but it'll be work nevertheless.
