I use Plesk 9.2.1 (on OpenSUSE 10.3) to define my domains/virtual hosts. For
PHP I can choose between 'Apache Module', 'FastCGI-Application' and
'CGI-Application'. I will skip the settings for Apache Module here.
Depending on what you select, Plesk does adjust the corresponding
use support for perl and python. The httpd.include sits in
/srv/www/vhosts/domain.tld/conf and is included from
/etc/apache2/conf.d/zz010_psa_httpd.conf (which gets included from
/etc/apache2/httpd.conf).
General configuration from /etc/apache2/sysconfig.d/loadmodule.conf (i left
out non-php-relevant entries):
LoadModule cgi_module
/usr/lib64/apache2-prefork/mod_cgi.so
LoadModule php5_module /usr/lib64/apache2/mod_php5.so
LoadModule fcgid_module /usr/lib64/apache2/mod_fcgid.so
LoadModule suexec_module
/usr/lib64/apache2-prefork/mod_suexec.so
Both CGI and FastCGI use
:/usr/bin/ # php-cgi5 -v
PHP 5.2.9 with Suhosin-Patch 0.9.7 (cgi-fcgi) (built: Mar 12 2009 16:17:38)

In my php.ini i have
; cgi.force_redirect is necessary to provide security running PHP as a CGI
under
; most web servers. Left undefined, PHP turns this on by default. You can
; turn it off here AT YOUR OWN RISK
; **You CAN safely turn this off for IIS, in fact, you MUST.**
; http://php.net/cgi.force-redirect
;cgi.force_redirect = 1
so it defaults to 1 which is why i set the same in mod_fcgid.conf via
'PHP_Fix_Pathinfo_Enable 1'.

So depending on what i set in Plesk the httpd.include file gets changed and
php files get parsed either with module mod_cgi.so or mod_fcgid.so (which is
a symlink to the 2.3.1 version i compiled) and both times with the same
binary /usr/bin/php-cgi5.
At least that is my understanding.
There is another difference looking at phpinfo():
Using mod_fcgid the only Environment variable i see is PATH. Using mod_cgi
there are a whole lot more Envrionment variables. To my understanding
variables shown under 'Environment' are Apache ENV variables.

Both use the same php.ini from /etc/php5/fastcgi/php.ini.
At least these variables are missing from mod_fcgid's phpinfo():
_SERVER["REDIRECT_STATUS"]
_SERVER["ORIG_SCRIPT_FILENAME"]
_SERVER["ORIG_PATH_INFO"]
_SERVER["ORIG_PATH_TRANSLATED"]
_SERVER["ORIG_SCRIPT_NAME"]
and of course the same _ENV variables as there is only _ENV["PATH"] set
anyway with mod_fcgid.
Concernig the shebang line in modify.php: From what i wrote, you can see,
that i do not put anything in modify.php. I use the script as written in my
first post. It will be parsed depending on the httpd.include file from above
(which is built from Plesk each time you change the configuraition there
from 'FastCGI-Application' to 'CGI-Application' using the same .htaccess.
Via the AddHandler and Action directive the image with watermark is shown
when using cfg-fcgi and PHP tries to parse the image when using mod_fcgid.
I hope this clearifies the situation a lot more instead of causing even more
confusion.
I was happy to give you even more information if you told me what you need.
I would really like to get this solved (and apologies concerning the
formatting of these variables).
TIA,
Marcus
