Hi,
i ran into a problem with mod_fcgid and i wonder whether anybody can replicate
my problem.
There is also a bug report in here:
http://sourceforge.net/tracker/?func=detail&aid=2854396&group_id=174879&atid=870991
Since i wrote the bug report, i did update to Apache 2.2.13, PHP 5.3.0 and
mod_fcgid 2.2 (was 2.1 before) but the error remains (should have upgraded
before <sigh> but that is why i write here now).
My server:
Operating systemLinux 2.6.9-023stab048.6-smp
CPUAuthenticAMD, Quad-Core AMD Opteron(tm) Processor 2352
Trying to replicate the problem just put a image.jpg file into a folder (i.e.
800x600 pixels) and another watermark.jpg like a banner 486x60 (size does not
matter, it should just be smaller than the original image).
Then put the following .htaccess into the same folder:
#---
RewriteEngine on
Options FollowSymlinks
RewriteBase /
AddHandler wtmrk jpg
action wtmrk /modify.php
#---
The code of the modify.php is this:

When i use this url http://www.domain.tld/image.jpg i get this error mesage
after updating to PHP 5.3.0 (from 5.2.6), Apache 2.2.13 (from 2.2.4) and
mod_fcgid 2.2 (from 2.1):
---
PHP Parse error: syntax error, unexpected '[' in
/srv/www/vhosts/httpdocs/image.jpg on line 234
PHP Warning: Unexpected character in input: '' (ASCII=16) state=0 in
/srv/www/vhosts/httpdocs/image.jpg on line 234
---
So, to me it seems the PHP parser tries to parse the content instead of the
browser sending it with the image/jpeg (or image/jpg) header.
When i use this url http://www.domain.tld/modify.php/image.jpg the image will
be shown with the watermark.
Any issues with the 'AddHandler' and/or 'action' statement in .htaccess
probably?
As soon as i switch from mod_fcgid to CGI or mod_php it does work using
http://www.domain.tld/image.jpg.
My httpd.include:
---
<IfModule mod_fcgid.c>
<Files ~ (\.php)>
SetHandler fcgid-script
FCGIWrapper /usr/bin/php-cgi5 .php
Options +ExecCGI
allow from all
</Files>
</IfModule>
---
My /etc/apache2conf.d/mod_fcgid.conf (i did only add "Passheader Authorization"
to it but this does not make a difference, obviously...):

I would appreciate any hints as i would prefer to use mod_fcgid.
Thanks in advance,
