PHProxy is an actually marginally useful example of the inelegant and kludgy 
handler logic in HTTPi/1.4'n'up. It implements just enough of the CGI
specification to allow PHP scripts to run through HTTPi.

When correctly configured, any file ending in .php will be automatically
and invisibly sent to PHP for interpretation by the server itself. phproxy
also honours New Security Model restrictions on UID access.

Requirements:

* PHP (4.3.x or better) -- you must compile the CGI server API version
  (usually in <php source directory>/sapi/cgi)
* HTTPi/1.4 or better (this will not work with previous versions)
* HTTPerl MUST be turned on in HTTPi -- see the configuration scripts

Installation:

* Make sure your PHP CGI server API executable is in a public place.
* Edit phproxy and follow the directions within to have it point to your
  CGI-based PHP executable. Put phproxy in a public place.
* Edit add_to_modules.in and follow the directions within to have it point
  to phproxy.
* Append the file add_to_modules.in to your server's modules.in.
* (Re)configure your HTTPi to incorporate the changes. ** REMEMBER: YOU
  MUST ENABLE HTTPerl OR PHPROXY CANNOT OPERATE! **
* Put phproxy_test.php in your document root and access it with a web
  browser. You should see the internal dump from phpInfo().

This code is at best hack-quality. Send bug reports and feature requests,
both of which will likely be sizable in quantity, to httpi@floodgap.com.
