Hi all,
I did a quick search in the bug tracker and the mailing list archives
and didn't see anything.
It looks like SetEnv PHPRC and Apache CGI redirection are not compatible.
When Apache is configured as indicated at
http://php.net/security.cgi-bin and as recommended at
http://www.php.net/manual/en/configure.php#configure.enable-force-cgi-redirect,
it appears that SetEnv PHPRC cannot be used to specify a php.ini.
SetEnv PHPRC works (and can be seen when tested with a traditional CGI
script, say written in Perl) but when the request goes to PHP via the
internal Apache redirect, the PHPRC environmental variable gets
rewritten as REDIRECT_PHPRC. This is why the CGI SAPI checks for the
existence of the environmental variable REDIRECT_STATUS if
"--enable-force-cgi-redirect" is specified.
Would it be reasonable to patch php_ini.c to check REDIRECT_PHPRC if
FORCE_CGI_REDIRECT is defined? This way both the SetEnv method and the
shell wrapper exporting PHPRC will work.
I just discovered the problem today, and have only skimmed through the
php_ini.c code. Doesn't look too difficult to add to the search_path,
but the ini_filename would probably require some sort of policy decision
(which has precedence if both PHPRC and REDIRECT_PHPRC exist -- I assume
PHPRC would).
Curious about how others feel about this issue.
Thanks,
Tienshiao
