title: Using SOAP wsHttpBinding from PHP
body: <p>I have a server that only offers a <code>wsHttpBinding</code> web service and need to use it from PHP.
  The standard SoapClient doesn't work with it, giving the following error:</p>
  
  <blockquote>
    <p><a href="http://www.w3.org/2005/08/addressing/faults:Sendera:ActionMismatch" rel="nofollow">http://www.w3.org/2005/08/addressing/faults:Sendera:ActionMismatch</a> The SOAP action specified on the message, '', does not match the HTTP SOAP Action, '<a href="http://tempuri.org/ICategoryApi/Tree" rel="nofollow">http://tempuri.org/ICategoryApi/Tree</a>'. a:Action</p>
  </blockquote>
  
  <p>Is there some PHP SoapClient implementation or setting that supports <code>wsHttpBinding</code>?</p>
