Generally I make sure that the parts of my code that start an output 
buffer are also responsible for closing the output buffer.. so something 
like this wouldn't be uncommon in my code..


ob_start();
try {
  do_something();
} catch (Exception $e) {
   ob_end_clean();
   throw $e;
}

$data = ob_get_clean();
