Problem: doc_root fails in safe_mode with PHP4.0.2

If I set the following in my /usr/local/lib/php.ini

safe_mode  = On
doc_root   = /u/vhome

I get:
Warning: Unable to access /u/vhome/u/vhome/ik.ca/www/old/info.php3 in
Unknown on line 0
Warning: Failed opening '/u/vhome/ik.ca/www/old/info.php3' for inclusion
(include_path='.:/usr/local/lib/php') in Unknown on line 0

Notice in the first line the /u/vhome is there twice.

If I turn off safe_mode or remove doc_root then its fine.

Thanks,
Gerald Villemure

what are ownership/permissions on /u/vhome/u/vhome/ik.ca/www/old/ and /u/vhome/u/vhome/ik.ca/www/old/info.php3?
 [2000-09-03 06:15 UTC] gvillemure at ik dot ca 
The path: /u/vhome/u/vhome/ik.ca/www/old/ dose not exist.

The real path is: /u/vhome/ik.ca/www/old/

The /u/vhome is where I am trying to set doc_root to but if I turn on safe_mode I get path the error.

The ownership/permissions in /old are:

drwxr-xr-x  29500:98 .
-rw-r--r--  29500:98 info.php3

The Apache server is running as user 98 group 98.

bug report #6491 seems to be related to this one.

Are you sure you're not doing
include "/u/vhome/ik.ca/www/old/info.php3"?
safe_mode and doc_root ALWAYS appends the doc_root to the filename as far as I know. It doesn't check that the include you're doing is actually under the doc_root. You should use relative pathnames and not full paths.
Anyway, let us know if we can close this bug.

The content of info.php3 is:
<?php
phpinfo();
?>

I am referring to the file directly with:
http://bkp.ik.ca/old/info.php3

Possibly relevant setting in php.ini:
safe_mode               = On
safe_mode_exec_dir      = /u/vhome/php3-safe
safe_mode_allowed_env_vars = PHP_
memory_limit            = 8388608
auto_prepend_file       =
auto_append_file        =
include_path            =
doc_root                = /u/vhome
user_dir                =
upload_max_filesize     = 20971520
extension_dir           = ./
enable_dl               = On

These setting are the same as what I use with 4.0.1pl2 and the problem dosen't come up...

Note that I have receive emails from other users stating they have the same problem.

I recently installed 4.0.3pl1 and the problem is no longer there.
