What actualy happends is: 1.) The outputbuffer 'My name is Dennis Pallett' is zipped by the ob_gzhandler. 2.) The zipped buffer is send down to the next callback 'mycallback' 3.) Function 'mycallback' unzipps the buffer 4.) Function 'mycallback' replaces 'Dennis Pallett' 5.) Function 'mycallback' rezipps the buffer The callbacks are called as 'last in, first out'. You could simply change the order of the callbacks to get the expected result. Yes you might do that, though this is not a logical thing to do. What actualy happends is:
