title: How to generate a new GUID?
body: <p>I'm working on a web service which requires a new <code>GUID()</code> passed as a reference to a method within the service. </p>
  
  <p>I am not familiar with <code>C#</code> or the <code>GUID() object</code>, but require something similar for <code>PHP</code> (so create a new object which from my understanding returns an <code>empty/blank GUID</code>). </p>
  
  <p>Any ideas?</p>
