PHP does not protect output_buffers created via configs through the output_buffer, output_handler configurations from individual scripts.  If you configure your php.ini to have output_handler = ob_gzhandler  then run ob_clean() or ob_end_clean() odd results happen and the page does not properly send.  I think PHP should protect buffers created before the script is executed so that the individual may not destroy them.

Try this: 

// delete as much output buffers as possible
while(@ob_end_clean());

I do not want PHP to delete the buffers.  Let me try and re-explain it.  When I setup the ob_gzhandler, then I run ob_clean or ob_clean_flush PHP will send a partially gzip'ed page to the browser or inconsistant results and the page will not display properly.  What I am suggesting is that if someone sets ob_gzhandler in the PHP.ini, or a situation like this, they cannot clear it out through the script.  It is protected.
