[PATCH] Repost - Adding Output Filters w/ Apache2 Handler SAPI

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)...

Woohoo!
This is an awesome patch..
I hope it gets accepted into PHP proper.

Can you please give an example on how this can be used?

I am using it in a PHP web app I am writing where I am generating XML
output and running it through an XML filter via XSLT (mod_transform). And
I can then selectively turn the filter on and off.. IE for XML data that I
don't want transformed, or for non-xml data.

I added two new functions for handling output filters in the
Apache2Handler SAPI:

bool apache_add_output_filter(string filter_name) - Attempts to add the
named filter to the Filter Chain.

array apache_get_output_filters() - Returns an array of all Active
Output filters for this request

The ability to add an output filter is very helpful in the apache
2model. For example with this I was able to add an XSLT output filter
that I use in other areas to render XML generated from PHP to HTML.

The attached patches are for both PHP4 CVS and PHP5 CVS. They are also
online at: http://force-elite.com/~chip/patches/php-src/apache2-filters/

I posted this patches last Monday, but received 0 replies. Are the
patches acceptable, is there anything to change, or are there any
comments?

Thanks,
