Simple query question ?

[fla5h]

I'm putting this in showthread.php

just after

PHP Code:

while ($post=$DB_site->fetch_array($posts) and $counter++<$perpage) { 


I want it to return the userid so I can test it against the userid opening the thread.

Like on here where we have the titles big at the top, I want a different template showing to the normal member than the member that posted the thread.

Got the template location etc sorted, just cannot get the condition statement working

PHP Code:

         if ($firstpostinfo==$bbuserinfo[userid]) { 

                    eval("\$threadheader = \"".gettemplate("showthread_member_header")."\";");

              } else {

             eval("\$threadheader = \"".gettemplate("showthread_poster_header")."\";");

      } 


So am wondering if the first query is correct ?

Is there a way of debugging php etc, say a step through the code line by line ?

Thanks
