Subject: Re: [PHP-DEV] [PATCH] Repost - Adding Output Filters w/  Apache2 Handler SAPI
From: jevon@jevon.org ("Jevon Wright")

What if you extended this to cover PHP in general - you could make your PHP
always generate XML data and then with add_output_filter(proprietary string
or callback function) you could make PHP transform the output at the end of
the script execution (possibly multiple times). I know a lot of developers
which are interested in a script -> xml -> xml -> xml -> xhtml pipeline, and
something like add_output_filter() might be a godsend :)

Yeah, I know it can be done in userland (somewhat)...
