ob_start("ob_gzhandler") and error handling functions

Hi, I include a php file at the beginning of every web page in this site. This include file has an error handling function and starts output buffering... // Start of Error Handler error_reporting(E_ALL ^ E_NOTICE); ini_set('log_errors','1'); function ErrHandler($err,$err_string='',$err_file,$err_line) {

       // Do error logging thang

       ob_end_clean();// Clear buffer
         include('/path/incs/errors/errors.inc');// Output friendly error page
       exit();
   }   

set_error_handler('ErrHandler'); // End of Error Handler It works great and the error handler kicks in if there is an error on the page and outputs a friendly page instead. I really wanted to gzip the pages by using ob_start("ob_gzhandler") but it doesn't work. I think it is because of the error handler function trying to clear the buffer (see the line ob_end_clean() which I assume becomes ob_end_clean("ob_gzhandler") ). It says on the php functions page- *ob_start()* may not be called from a callback function. If you call them from callback function, the behavior is undefined. If you would like to delete the contents of a buffer, return "" (a null string) from callback function. As I am new to this- I don't really understand what it is trying to get at. Is there a way of me using my error handler and evoking the ob_start("ob_gzhandler") ? Thanks. Ianob_ |ob_start("ob_gzhandler");|
