Any PHP experts out there?
The basic problem from your description is that PHP thinks the .jpg file is
the PHP script and tries to parse that (instead of modify.php). I easily
duplicated that.
I then looked up the setting of cgi.fix_pathinfo. My php.ini has a comment
that says it defaults to 1. mod_fcgid has a setting that is supposed to
mirror that (PHP_Fix_Pathinfo_Enable). So I set "PHP_Fix_Pathinfo_Enable 1"
in my mod_fcgid configuration, but still no change in failure.
I then edited php.ini, set cgi.fix_pathinfo=0, set "PHP_Fix_Pathinfo_Enable
0" (the default) in my mod_fcgid conf, and retested.
Now PHP is trying to run modify.php instead of interpreting a .jpg file
(good!). It fails to open the file properly ("*Warning*:
getimagesize(./wtmrk./IMG_4418.jpg)") but that may be something about how I
attempted to set up modify.php.
So set "cgi.fix_pathinfo=0" in the proper* php.ini and try again. (*You may
have a separate one for mod_php vs. "CGI"; set the latter one.)
BTW, here were the request environment settings sent over by mod_fcgid:
SCRIPT_FILENAME=/home/trawick/inst/22/htdocs/modify.php
REDIRECT_URL=/wtmrk/IMG_4418.jpg
REQUEST_URI=/wtmrk/IMG_4418.jpg
SCRIPT_NAME=/modify.php
PATH_INFO=/wtmrk/IMG_4418.jpg
PATH_TRANSLATED=/home/trawick/wtmrk/IMG_4418.jpg
Another way to look at it is to consider if mod_fcgid is doing the right
thing when PHP_Fix_Pathinfo_Enable is 1 (matching PHP's default). I don't
know about that ;)
That logic (in mod_fcgid.c) is as follows:
/* "DOCUMENT_ROOT"/"SCRIPT_NAME" -> "SCRIPT_NAME" */
const char *doc_root = apr_table_get(e, "DOCUMENT_ROOT");
const char *script_name = apr_table_get(e, "SCRIPT_NAME");
if (doc_root && script_name
&& apr_filepath_merge(&merge_path, doc_root, script_name, 0,
r->pool) == APR_SUCCESS) {
apr_table_setn(e, "SCRIPT_NAME", merge_path);
}
In our example, the Action for wtmrk is defined as "/modify.php", so
SCRIPT_NAME is "/modify.php" when we get here. apr_filepath_merge() just
returns the 3rd parameter when it starts with "/", so our supposedly-merged
script name is unchanged. That's not what I would have expected. (Also, I
wonder what happens when SCRIPT_NAME is outside of DOCUMENT_ROOT.)
Recap: Try cgi.fix_pathinfo=0; maybe somebody else will chime in on the
PHP_Fix_Pathinfo_Enable processing.

Well, it's been a while but as i want other people to find a solution should
they dig in old archives via Google, i wanted to share wiht you how i got
around 'the wonderful world of Plesk' (no, i did not deinstall it...).
Please acknowledge that i am neither a guru of Apache, mod_fcgid nor PHP. I
simply want to help people who might face the same problem than i did about
6 months ago. If you read this whole thread, then you know about the
problems arising in certain -special- environments when you want to use
mod_fcgid (i.e. active watermarking images like i did).
My current environment as of writing this is:
- suse-10.3-x86_64-plesk9
- Plesk 9.2.3
- Apache 2.2.4 with MPM-worker enabled
- PHP 5.2.9
- mod_fcgid 2.3.5 (with 'FcgidFixPathinfo 1' in
/etc/apache2/conf.d/mod_fcgid.conf)
The 'FcgidFixPathinfo 1' in /etc/apache2/conf.d/mod_fcgid.conf corresponds
to
---
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for
CGI. PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to
not grok
; what PATH_INFO is. For more information on PATH_INFO, see the cgi specs.
Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec. A
setting
; of zero causes PHP to behave as before. Default is 1. You should fix
your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; http://php.net/cgi.fix-pathinfo
;cgi.fix_pathinfo=1
---
in /etc/php5/fastcgi/php.ini as cgi.fix_pathinfo=1 is the default. I mention
it here because i refer to it later.
To avoid problems in an active watermark php script (caused by SetHandler
and FCGIWrapper directives - please read the entire thread for details),
this is what i did:
In Plesk, choose "PHP Support via CGI" from the dropdown menue in your
<domain> "Web Hosting Setup".
This will add
---
<Files ~ (\.php)>
AddHandler php-script .php
Options +ExecCGI
allow from all
</Files>
---
to your <domain>/conf/httpd.include file. Now, how do we get to use
mod_fcgid then?
In /etc/sysconfig/apache2 you (hopefully) have:
---
APACHE_MODULES="<modules> cgi <moremodules> fcgid <evenmoremodules> suexec"
---
so mod_fcgid.so will be included in
/etc/apache2/sysconfig.d/loadmodule.conf.
In the order you included your modules above, mod_cgi.so will be implemented
before mod_fcgid.so and therefore /etc/apache2/conf.d/php_cgi.conf will be
parsed before /etc/apache2/conf.d/mod_fcgid.conf. Do i make sense?
What does this mean?
In /etc/apache2/conf.d/php_cgi.conf we have
---
scriptAlias /phppath/ "/usr/bin/"
Action php-script /phppath/php-cgi5
---
(this was mentioned in here before). Actually this causes all PHP scripts to
be parsed by mod_cgi. Hmm.... Fine. Let's add a vhost.conf in
/srv/www/vhosts/<domain>/conf/
like this: /srv/www/vhosts/<domain>/conf/vhost.conf
---
<OtherImportantStuff>
Include /srv/www/vhosts/global.vhost.conf
---
What? This is because i want ALL domains to use PHP via mod_fcgid yet i do
not want to change every vhost.conf manually which is why i use this
'Include'.
/srv/www/vhosts/global.vhost.conf:
---
<IfModule mod_fcgid.c>
Alias /phpfcgidpath/ "/usr/bin/"
Action php-script /phpfcgidpath/php-cgi5
<Location /phpfcgidpath/>
SetHandler fcgid-script
Options +ExecCGI
</Location>
</IfModule>
---
Now, what do we do here? Well, we define an alias similiar like in
/etc/apache2/conf.d/php_cgi.conf but via the Action statement and the
following Location container, all Files ending (\.php) will now get parsed
using mod_fcgid because of the
---
SetHandler fcgid-script
---
If you have set 'FcgidFixPathinfo 1' in
/etc/apache2/conf.d/mod_fcgid.conf -as explained above- calling phpinfo()
will tell you this
---
_SERVER["ORIG_SCRIPT_NAME"] /phpfcgidpath/php-cgi5
---
which means, mod_fcgid has been used to parse the php file. This is what we
wanted to achieve.
Instead of using a (global) vhost.conf file, you could probably put
everything into /etc/apache2/conf.d/mod_fcgid.conf but this is like with
Rome: There are more than one ways to achieve your goal. I just wrote about
how I succeeded. Feel free to find your own way.
HTH.

BTW, I'm sorry I haven't followed up to your last couple of posts. I
should be honest with you: All that Plesk-generated config and/or
attempts to interject tweaks to that config makes my head explode.
Maybe somebody else here has the time and will power to dig through
it.
My general thoughts: I don't think mod_fcgid's processing can be
compared to mod_php's in any meaningful way. Instead, it should be
compared to mod_cgi's (mod_cgid's). FastCGI is essentially CGI, but
with the request information passed over in a way that allows the
script to handle multiple requests without exiting. mod_cgi and
mod_fcgid should pass the same request environment variables to the
CGI/FastCGI application, and in fact they use the same core httpd code
to build that information. (The notable exception is when
FcgidFixPathInfo is turned on, in which case mod_fcgid modifies one of
the request environment variables I can't say if/when exactly that
helps.)
Good luck!

Re: mod_fcgid: Problem serving binary content with Apache 2.2.13 - PHP 5.2.9
Posted by Marcus Merz <mm...@gmx.de>.
Hi Jeff,
after another evening, this is what i came up with:
Goals:
1. I do not want to mess around with /etc/apache2/conf.d/mod_fcgid.conf
2. I do not want to be forced to always use mod_fcgid on virtual hosts that are configured for mod_cgi (from Plesk)
I achieve this by doing all necessary changes in /srv/www/vhosts/<domain.tld>/conf/vhost.conf (in case of a subdomain ist could also be /srv/www/vhosts/domain.tld/subdomains/<subdomain>/conf/vhost.conf) and amending the respective httpd.include file (in /srv/www/vhosts/<domain.tld>/conf as well).
The downside is, that this httpd.include file gets generated by Plesk whenever you change anything for that virtual host or a subdomain for that virtual host. There is an event manager in Plesk where you can specify to run a specific script after an event has taken place like 'hosting domain create/update' to reverse any changes to httpd.include but it would require more work and knowledge to write such a script, i.e. cutting the respective <IfModule mod_fcgid.c> container (see below) and adding necessary code either in httpd.include or a vhost.conf file. Certainly it is doable, though.
Fine.
[btw, maybe it was my fault but using your replacement code 1:1 causes every file (tested with php or jpeg) to be offered for download by the browser (tested on 2 different computers with FF 3.5.3, IE 6 and IE 8)]
To get mod_fcgid running with this watermark script and not to interfere with virtual hosts configured to use mod_cgi, i did amend/extend a couple of things, plus, i did add FCGIWrapper statement back in which might be useless but i wanted to know whether that directive is part of the problem. Actually it is not. The problem starts when using 'SetHandler fcgid-sript' instead of an Alias/Action combination.
/etc/apache2/conf.d/mod_fcgid.conf is back to 'out-of-the-box' configuration. I only added
PassHeader Authorization
PHP_Fix_Pathinfo_Enable 1
like before.
My httpd.include is:
<VirtualHost <IP>:80>
...
<Directory /srv/www/vhosts/domain.tld/httpdocs>
<IfModule mod_perl.c>
<Files ~ (\.pl$)>
SetHandler perl-script
PerlHandler ModPerl::Registry
Options ExecCGI
allow from all
PerlSendHeader On
</Files>
</IfModule>
<IfModule mod_python.c>
<Files ~ (\.py$)>
SetHandler python-program
PythonHandler mod_python.cgihandler
</Files>
</IfModule>
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
# <IfModule mod_fcgid.c>
# <Files ~ (\.php)>
# SetHandler fcgid-script
# FCGIWrapper /usr/bin/php-cgi5 .php
# Options +ExecCGI
# allow from all
# </Files>
# </IfModule>
Options -Includes -ExecCGI
</Directory>
Include /srv/www/vhosts/domain.tld/conf/vhost.conf
</VirtualHost>
so you could skip/delete the second <IfModule mod_fcgid.c> container from httpd.include.
The included vhost.conf file then contains:
---
Alias /phpfcgidpath/ "/usr/bin/"
Action php-fcgid /phpfcgidpath/php-cgi5
<Location /phpfcgidpath/>
SetHandler fcgid-script
Options +ExecCGI
</Location>
<Files ~ (\.php)>
SetHandler php-fcgid
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
---
The first two statements are basically similiar to the /etc/apache2/conf.d/php_cgi.conf (and needed as i did replace /phppath/ with /phpfcgidpath/ for which there is no ScriptAlias and Action statement in any other *.conf file):
---
scriptAlias /phppath/ "/usr/bin/"
Action php-script /phppath/php-cgi5
---
As i wanted to have a testconfig which does not interfere with mod_cgi, i changed from /phppath/ to /phpfcgidpath/ and did use Alias instead of ScriptAlias because you used it in your replacement bit. In the end it does not really matter.
This causes only virtual hosts which have this additional statement in its vhost.conf to use mod_fcgid and the watermark image works with this configuration.
As soon as you change the SetHandler statement in the vhost.conf from:
<Files ~ (\.php)>
SetHandler php-fcgid
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
to
<Files ~ (\.php)>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
(which is the default from Plesk in httpd.include when switching to FastCGI-Application), PHP tries to parse the jpg file again. This is expected as changing the SetHandler directive as shown, the Alias and Action directive are not used anymore as we do not use the Handler php-fcgid anymore and we are back to square one.
Using this 'workaround' does have one other side-effect:
As we are using a Alias (or ScriptAlias) directive, now, when we call an URL from a .htaccess protected directory -AuthType Basic in connection with PassHeader Authrization-, the _SERVER["REMOTE_USER"] variable is empty and _ENV["REDIRECT_REMOTE_USER"] is used instead. This is not really a problem, but when you try to use PHP Auth, you have to adopt your scripts not only to test for REMOTE_USER but also for REDIRECT_REMOTE_USER like
<?php
if (!isset($_SERVER["REMOTE_USER"]) && !isset($_SERVER["REDIRECT_REMOTE_USER"])) {
echo "Not authenticated";
} else {
<do something else>
}
?>
As i am curious, i would like to know what the difference in the mod_fcgid source code is to cause such a different behaviour. Obviously you can get it to work by the use of the Alias / Action combination with the SetHandler directive but when using it as shown in the docs (and implemented by Plesk and a couple of other GUI's i would guess) then this watermark script (and variations of them) fail(s).
HTH,
Marcus

Please try translating the CGI config directly to FastCGI as noted above, instead of using the Plesk-generated config, and let us know what happens.
Replace this bit
<Files ~ (\.php)>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
Allow from all
</Files>
with
Alias /phppath/ /usr/bin/
<Location /phppath/>
SetHandler fcgid-script
Options +ExecCGI
</Location>
I could not get it to work in my httpd.include file as Apache was always throwing an error (i.e. Alias not allowed here, Location not allowed here etc....).
I ended up changing my /etc/apache2/conf.d/mod_fcgid.conf (excerpt) from:
---
##

## uncomment the following line if you want to handle php via mod_fcgid
##

so basically inserting your replacement code at the bottom inside the <IfModule fcgid_module> container.
Now there are two things:
1) On virtual hosts which use 'FastCGI-Application' in Plesk and which httpd.include looks like this:
<VirtualHost <IP>:80>
...
<Directory /srv/www/vhosts/domain.tld/httpdocs>
<IfModule mod_perl.c>
<Files ~ (\.pl$)>
SetHandler perl-script
PerlHandler ModPerl::Registry
Options ExecCGI
allow from all
PerlSendHeader On
</Files>
</IfModule>
<IfModule mod_python.c>
<Files ~ (\.py$)>
SetHandler python-program
PythonHandler mod_python.cgihandler
</Files>
</IfModule>
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
<IfModule mod_fcgid.c>
<Files ~ (\.php)>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
</IfModule>
Options -Includes -ExecCGI
</Directory>
Include /srv/www/vhosts/domain.tld/conf/vhost.conf
</VirtualHost>
a) I sometimes get all files offered to download (not really able to replicate this, it seems it is connected to the use of .htaccess and modify.php in the same directory i sometimes get php files with image/jpeg header for download, sometimes with x-httpd-php header...kind of bizarre...) and
b) The watermark image still fails for the same reason as stated before: PHP tries to parse the image.
I have proof that this config uses mod_fcgid because phpinfo() gives only _ENV["PATH"] under Environment plus i do get a _SERVER["Authorization"] and other Auth variables when calling phpinfo() from a .htaccess secured directory (AuthType Basic) which was not the case if it was mod_cgi.
2) Virtual hosts which use 'CGI-Application' in Plesk and which httpd.include therefore looks like this:
<VirtualHost <IP>:80>
...
<Directory /srv/www/vhosts/domain.tld/httpdocs>
<IfModule mod_perl.c>
<Files ~ (\.pl$)>
SetHandler perl-script
PerlHandler ModPerl::Registry
Options ExecCGI
allow from all
PerlSendHeader On
</Files>
</IfModule>
<IfModule mod_python.c>
<Files ~ (\.py$)>
SetHandler python-program
PythonHandler mod_python.cgihandler
</Files>
</IfModule>
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
<Files ~ (\.php)>
AddHandler php-script .php
Options +ExecCGI
allow from all
</Files>
Options -Includes -ExecCGI
</Directory>
Include /srv/www/vhosts/domain.tld/conf/vhost.conf
</VirtualHost
do get parsed using mod_fcgid as well now. Maybe this makes sense because in my /etc/apache2/sysconfig.d/loadmodule.conf the mod_cgi.so comes before mod_fcgid.so:
---
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
---
and as the mod_fcgid.conf is read later(?) than mod_cgi.conf, the Alias setting and the SetHandler fcgid-script take precedence which is why mod_fcgid is used regardless of the Plesk setting, plus:
THE WATERMARK IMAGE SCRIPT DOES WORK !
To recap:
1. Using your replacement bits at the bottom of mod_fcgid.conf as stated above
2. Using the httpd.include (excerpt) with
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
<Files ~ (\.php)>
AddHandler php-script .php
Options +ExecCGI
allow from all
</Files>
the watermark image gets displayed and phpinfo() states that mod_fcgid is used.
When in 2. you would choose 'FastCGI-Application' in Plesk which causes the httpd.include (excerpt) to look like this:
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
<IfModule mod_fcgid.c>
<Files ~ (\.php)>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
the watermark image fails with the same error like in the beginning:
Warning: Unexpected character in input: '' (ASCII=16) state=1 in /srv/www/vhosts/domain.tld/httpdocs/image.jpg on line 234
Parse error: syntax error, unexpected '[' in /srv/www/vhosts/domain.tld/httpdocs/image.jpg on line 234
I do not know what the bottom line concerning mod_fcgid is in terms of coding but at least for me i can say that with the additions in mod_fcgid.conf and using 'CGI-Application' in Plesk, i could use mod_fcgid in all my domains/virtual hosts.
I am glad to help where i can trying to get mod_fcgid to work in Plesk without this 'work-around'. I do not have a clue of C(++), though. But if this thread helps to improve mod_fcgid then that already is a goal (to me).
Let me know what you think.

I am sorry. It was meant to read:

I copied the wrong part from my php.ini. Also for the missing environment
variables i should have tested from the same conditions but i did
http://domain.tld/phpinfo.php on mod_fcgid config and
http://www.domain.tld/admin/phpinfo.php on the mod_cgi config. A difference
in variables is to be expected then. I will get back to this later today and
retest.

I get a configuration error when i try to do replace that bit (in the lines
where i put a *) and 'rcapache2 reload' after because that part sits in a
VirtualHost container nested within <Directory>. The first error was: "Alias
not allowed here":
<VirtualHost <IP>:80>
...
<IfModule mod_fcgid.c>
<Files ~ (\.fcgi)>
SetHandler fcgid-script
Options +FollowSymLinks +ExecCGI
</Files>
</IfModule>
<IfModule mod_fcgid.c>

* Options +ExecCGI
* allow from all
* </Files>
</IfModule>
Options -Includes -ExecCGI
</Directory>
Include /srv/www/vhosts/domain.tld/conf/vhost.conf
</VirtualHost>
but i got your point. I will try to replicate your setup later today.
At least i am glad to hear that the script works with mod_fcgid if using the
same config than with mod_cgi.

I'm not aware of a connection between cgi.force_redirect and
PHP_Fix_Pathinfo_Enable. What do you know about that?

SetHandler fcgid-script
FCGIWrapper /usr/bin/php5-cgi .php
Options +ExecCGI
Allow from all
</Files>
AddHandler php-script .php
Action php-script /phppath/php5-cgi

As before, this only came close to working for me with cgi.fix_pathinfo=0.
With the CGI configuration in hand, then I tried to convert that directly to
FastCGI.
Theoretically we should just change the handler from cgi-script to
fcgid-script and it should work. But the CGI configuration uses ScriptAlias
as a short-cut for
Alias /phppath/ /usr/bin/
<Location /phppath/>
SetHandler cgi-script
Options +ExecCGI
</Location>
When I use that expansion of ScriptAlias, and convert the cgi-script to
fcgid-script, I now get this for the FastCGI configuration:
AddHandler php-script .php
# ScriptAlias /phppath/ /usr/bin/
Alias /phppath/ /usr/bin/
<Location /phppath/>
SetHandler fcgid-script
Options +ExecCGI
</Location>
Action php-script /phppath/php5-cgi
<Directory /usr/bin/>
Allow from all
</Directory>
<Files ~ (\.php)>
AddHandler php-script .php
Options +ExecCGI
Allow from all
</Files>
That's the direct translation of the CGI configuration to a FastCGI
configuration. And the script works for me now via FastCGI, without
changing cgi.fix_pathinfo to 0. (I'm not setting PHP_Fix_PathInfo_Enable
either.)

AFAICT, if Plex was creating a mod_fcgid configuration that was an exact
translation from the mod_cgi configuration, it would work with mod_fcgid.

That is to be expected.
The CGI process is created for every request, so the Apache subprocess env
data is passed over as a native/OS environment variable when the process is
created.
The FastCGI process is started and intended to be run for many different
requests; the Apache subprocess env data is passed over on a socket with
the actual request.
The important stuff is populated in _SERVER[].

I looked at PHP itself and there is quite a lot of processing of such
variables at startup. That's where the answer is, but I don't know the
details. mod_fcgid and mod_cgi use the same core Apache function to set up
the subprocess env table. The only difference is that mod_fcgid changes
SCRIPT_NAME when PHP_Fix_PathInfo_Enable is set.

I didn't need the shebang line when I switched to the actual config you're

No problem.
Please try translating the CGI config directly to FastCGI as noted above,
instead of using the Plesk-generated config, and let us know what happens.

Posted by Marcus Merz <mm...@gmx.de>.
As an additional note, i found another watermark script which fails with the
same error (it will need the same .htaccess as in my first post - save the
script as modify.php as well or adjust the name in .htaccess accordingly) as
PHP will try to parse the jpg file instead of displaying the image.
Again, switching to cgi-fcgi or mod_php, the image gets displayed
(differences between mod_fcgid and mod_cgi as shown in the httpd.include in
my previous post):

I wonder whether i have a special environment which causes this behaviour
only with me. Otherwise i would expect a lot more 'noise' from other people
when switching to mod_fcgid from either mod_php or mod_fastcgi as these
scripts will fail.

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
httpd.include for the respective domain (i.e. virtual host). Furthermore i
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

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

What is your configuration to run modify.php as a CGI? Do you add a shebang
line, or use something else?
Here's my configuration:
LoadModule fcgid_module modules/mod_fcgid.so
<Directory /home/trawick/inst/22/htdocs/wtmrk/>
Allow from all
AddHandler wtmrk jpg
Action wtmrk /modify.php
</Directory>
<Files ~ (\.php)>
<IfModule mod_fcgid.c>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php5-cgi .php
</IfModule>
<IfModule !mod_fcgid.c>
SetHandler cgi-script
</IfModule>
Options +ExecCGI
Allow from all
</Files>
I comment out the LoadModule directive to switch to CGI. I had to add a
shebang line to the top of modify.php.

Thanks for your comments. Surprisingly setting cgi.fix_pathinfo=0 in php.ini
does not change the behaviour calling http://www.domain.tld/image.jpg . PHP
still tries to parse the jpg, same as with the default setting of
cgi.fix_pathinfo=1in php.ini. What *does* change is, that when calling
http://www.domain.tld/modify.php/image.php (for test purposes) instead of
displaying the image -which worked before with cgi.fix_pathinfo=1 (or
uncommented as 1 is default), PHP tries to parse the jpg as well:
Warning: Unexpected character in input: '' (ASCII=16) state=1 in
/srv/www/vhosts/image.jpg on line 234
Parse error: syntax error, unexpected '[' in /srv/www/vhosts/image.jpg on
line 234
I did check with phpinfo() that cgi.fix_pathinfo was 0 and 1 each time i
tested.
What is new is, that using CGI instead of mod_fcgid, with cgi.fix_pathinfo=0
the script now fails with a 'No input file specified' message in the
webbrowser. There is no error logged in error_log but a 404 is logged in
access_log for /image.jpg.
Obviously using mod_php it works regardless of setting cgi.fix_pathinfo=0 or
1 as it is not taken care of anyway and so the image gets displayed each
time.
To recap:
setting cgi.fix_pathinfo=0 causes mod_fcgid to parse the jpg file (same
behaviour as before) using http://www.domain.tld/image.jpg *AND*
http://www.domain.tld/modify.php/image.php
Switching back to cgi.fix_pathinfo=1 and using CGI instead of mod_fcgid, the
image gets displayed 'out-of-the-box.
I suspect there are differences in mod_fcgid.conf which default settings
cause this behaviour because the php.ini is the same for both. I will take a
closer look into the docs for 2.3.1 and trying to find a solution there.
Of course i was glad if somebody else knows the solution.
Thanks,
Marcus
