Re: problem: Debian apache2 + php4-cgi + attachments

Heya,

me again :)

I haven't been able to get PHP4 working with Apache2 when PHP4 is
compiled as a lib (instead of the CGI variant). Segfaults and
whatnot. So I've investigated further. The problem is that, in the setup
with PHP4 being executed as a CGI script, php4 is being executed but it
cannot find the file in question. This is because it evaluates
PATH_TRANSLATED which gets set by the browser to (in my case)
/home/www/bunkus.org/html/anthill/showattachment.php/21/a.txt while
PATH_INFO contains /anthill/showattachment.php/21/a.txt.

My solution is to replace /usr/lib/cgi-bin/php4 with a small shell
script that cuts off everything after .php and then calls the php4
binary. This is of course a performance hit, but my server is definitely
not THAT busy.

Now I encountered another problem with showattachment.php. As you can
see above PATH_INFO contains the complete path to the script and not
just the parameters /21/a.txt. showattachment.php however expects 21 and
a.txt to be at the start of the array that you get after splitting up on
/. I just modified those two lines like this:

 $result = $db->query("SELECT * FROM attachidx WHERE atid = $id");
 dberror($result);


Perhaps you can commit this to CVS as well? It should not hurt if
PATH_INFO is only set to /21/a.txt, and it will work for me where it is
set to the complete path.
