Personally, the way i'd do it is to write a bit of php (or python, perl,
etc) called via fast cgi to read your fifo (be mindful of the blocking
nature of pipes which can cause such things to hang waiting for input).

but,
http://squirrelshaterobots.com/programming/php/building-a-queue-server-in-php-part-3-accepting-input-from-named-pipes/
is an example of reading a fifo from php. And it would be quite easy to
do something like this (kinda off the top of my head):

        location /location/of/my/fifo.html {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass
unix:/var/run/php-fastcgi/php-fastcgi.socket;
                fastcgi_param SCRIPT_FILENAME
/path/to/local/php/that/reads/pipe.php;
        }

within the nginx config...
