Hmm.. possibly something like this:

 
 
class Outputter {
 $sources = array();
 public function RegisterDataSource($datasource){
  if ($datasource typeof IDataSource){
   $sources[] = $datasource;
  }
 }
 public function PullData (){
  for (var $i=0; $i<sizeof($sources); $i++){
   $sources[i].PushData($this);
  }
 }
}
 
<p>interface IDataSource {
 PushData($outputter);
}
 
SessionManager implements IDataSource
{
  function PushData($outputter){
   $outputter.WriteElement(&quot;blah&quot;,$this-&gt;property); 
   $outputter.WriteCDataElement(&quot;blah&quot;,$this-&gt;anotherproperty);
 }
}
 
 
PlayerController implements IDataSource
{
  function PushData($outputter){
   $outputter.WriteElement(&quot;blah&quot;,$this-&gt;property); 
   $outputter.WriteCDataElement(&quot;blah&quot;,$this-&gt;anotherproperty);
 }
}
 
Authenticator implements IDataSource
{
  function PushData($outputter){
   $outputter.WriteElement(&quot;blah&quot;,$this-&gt;property);
   $outputter.WriteCDataElement(&quot;blah&quot;,$this-&gt;anotherproperty);
 }
}

..etc..

My brain is starting to hurt more.

"There's a difference between only needing one instance of a class, and needing only one instance of a class."

Gah.

The more I think about what it is I need to do, the more I'm losing concentration and the TV keeps seeming more and more interesting.

I'm starting to question my origional bit of code because I can't think of a situation where I'll need more than one output method.

I shall read your link. ta.

Hmm. I should've read my own code before I last posted. I KNEW i wasnt going to have more than one data output object, but knew i was going to have more than one data source.

Gah im going insane. Far too many hours coding without a break.

... Except php doesnt really support xsl. and as this is open source I better think of a better way.

I need to stop talking to myself.
