open_basedir

[sreniaw@wp.pl]

Hello,
I use php 5.1.4 with apache 2.2.2 on Solaris 10.
The problem is that I can't configure open_basedir
because I always get warming message:

Warning: readfile() [function.readfi le]: open_basedir restriction in
effect. File(test.txt) is not within the allowed path(s):
(/wwwroot/default) in /wwwroot/default/mk.php on line 3
Warning: readfile(test.t xt) [function.readfi le]: failed to open stream:
Not owner in /wwwroot/default/mk.php on line 3

open_basedir = /wwwroot/default
/wwwroot/default
- test.txt <- my txt file
- mk.php <- my script that read test.txt
<?
readfile("test. txt");
?>

My read file - test.txt is in open_basedir path.
When I use full path to the file everything is ok.

Do you have any clue ?

Image the following situation:

The text and script files are in the following dir:

/somedir/subdir

The script file includes the text file relatively to the current working
dir, as in:

readfile('test. txt');

The open_basedir directive is set as follows:

open_basedir = /somedir/subdir

Now, you cd to /somedir/subdir and execute the script: all is fine.

Next, you cd to /somedir and execute the script: it fails. Why?

Because you include the text file relatively to the current working dir
(cwd), PHP expects the text file to be in /somedir, simular to:

readfile('/somedir/test.txt');

And this is restricted, hence the error message. For this reason, using an
absolute path works, because this doesn't take the cwd into account.

The same applies to the safe_mode settings, which you also seem to use
according to the "Not owner" error.

To dynamically determine the absolute path, you could do something like:

readfile(dirnam e($_SERVER['PHP_SELF']) .'/test.txt');

You are right, but problem isn't in it.
On my home's FreeBSD box evrything works ok, but
on Solaris 10 I have to use absolute path's.
Why do I have to do it ?
