'onEndRequest'=>create_function('$event', 'return ob_end_flush();'),
```

An overview about this:

* PHP's `create_function` will create lambda functions in runtime, so you don't have to worry about external files. It'll take the parameter list and the internal code, respectively, and return the newly added function name, which will serve here as callbacks.
* Indexing these items as `onBeginRequest` and `onEndRequest` will trigger attaching callbacks to application events.
* Event handlers are even acceptable since they'll take the event object as first argument.
* Please visit official PHP site for more information regarding [ob_start](http://php.net/ob_start) and [ob_gzhandler](http://php.net/ob_gzhandler). In summary, the latter will check whether the client is compatible with gzipped content, set the Content-Encoding header and compress all the content generated during processRequest accordingly.
* If the current browser is not capable of uncompressing gzip, gzhandler will leave the output untouched.
