title: Where should I start for Web Services with PHP with C# Client?
body: <p>I have been working in C# for a while ago, and recently started again with PHP; and I wonder if it is possible to make web services in php that can be consumed from C#. </p>
  
  <p>Googling, i found various frameworks as NuSOAP, Zend and others.</p>
  
  <p>My questions are:</p>
  
  <ul>
  <li>What good frameworks are out there for doing SOAP Web Services development with PHP?</li>
  <li>Where can I start from?</li>
  <li>How can I achieve Database agnosticism in PHP?</li>
  </ul>
  
  <p>Thanks in advance</p>
