title: Add entries to OpenFire user's roster with PHP
body: <p>I'm working on an OpenFire's client which requires being able to add entries to a user's Roster. The client is developed in PHP. </p>
  
  <p>I've been looking into the OpenFire's database schema documentation, and tried implementing this by adding entries to the <code>ofRoster</code> table. This doesn't seem to be enough to achieve what I need. I have two questions:</p>
  
  <ol>
  <li>Do you know which tables I should look into to "emulate" what the admin console does for adding an entry to a user's Roster?</li>
  <li>Do you know of a better method for managing the Roster using PHP?</li>
  </ol>
