surround PHP with filters

maard has asked for the wisdom of the Perl Monks concerning the following question:

Hello, brothers in faith!

I have apache2 with mod_perl/mod_php and some php software running on it. And I want to filter request headers for php scripts and filter its output again (both headers and body). php scripts are located under /php_area. The problem is, that if I write

<Location /php_area>
  SetHandler modperl
  PerlInputFilterHandler My::PHPInputFilter
  PerlOutputFilterHandler My::PHPOutputFilter
</Location>
[download]

then php scripts stop being processed by mod_php and instead are output as plain php code.

For now I solved the problem by writing "proxy" response handler, which uses LWP to perform requests to php and give user back what I want (it's much simpler than fix all that php code), but i'm still interested in using filters - is it possible in this situation ?

If I understand it correctly, you can set up mod_perl as a filter at various stages of the process. You should be able to set up a filter to modify the requests before it gets to PHP. For more, go to http://perl.apache.org/docs/2.0/user/handlers/filters.html	[reply]

Yes, it is possible to do what you show in your sample here. The "SetHandler modperl" looks wrong to me, but the concept is correct. Did you actually write code for these filters?	[reply]

That SetHandler directive isn't wrong, see example in mod_perl2 filters. But I overlooked something obvious: use of <Files ~ "\.php"> instead of <Location>	[reply]
