I run into these types of things all the time, and find print_r() or
var_dump() invaluable to assure I know what I'm actually working with. 
Sometimes they don't fit just right, however, so I wrote a little
wrapper which will save some of the output buffering bothers and
optionaly put it to a log file instead of the browser.  I've included
it below.

H


function trigger_dump( $mixed,$error = 1 ) {
   if( $error === 0 ) {
      echo '<pre>';
      print_r($mixed);
      echo '</pre>';
   } else {
      ob_start();
      print_r($mixed);
      trigger_error(ob_get_contents());
      ob_end_clean();
   }
}
