I read a lot of topics about debugging a client-server application (most concerned SOAP client-server). 
I also wach the parallel debbugging video tutorial.
My question is how can I debug an Oauth client-server applicaion with PHPEd. 
This is the client code
 	
	| <?php
 $oauth_client = new Oauth("key","secret");
 $oauth_client->enableDebug();
 try {
 $info = $oauth_client->getRequestToken("http://localhost/oauth/oauth/request_token?oauth_callback=http://localhost/oauth/client/callback.php");
 
 } catch(OAuthException $E){
 echo "<pre>".print_r($E->debugInfo,true)."</pre>";
 }
 ?>

I tryed to put the DebugBreak(); function in the server code but I received an error "faild to resolve client adress".
All the server and client files are on the same linux remote server.
