Status: No Feedback
Bug Type: Scripting Engine problem
Operating System: Gentoo/Linux
PHP Version: 5.2.8
New Comment:
I confirm this bug. Here is the simplest reproduce code that I was able
to make up:
~$ cd /tmp
/tmp$ mkdir a
/tmp$ mkdir b
/tmp$ echo '<?php echo getcwd(); require "../inc.php";?>' > a/test.php
/tmp$ echo '<?php echo "ok\n";?>' > b/inc.php
/tmp$ ln -s /tmp/a b/c
/tmp$ cd b/c/
/tmp/b/c$ php -f test.php
/tmp/a
Warning: require(../inc.php): failed to open stream: No such file or
directory in /tmp/a/test.php on line 1
As one can see, the script's CWD is /tmp/a although the script was run
from /tmp/b/c. As a result the following require() instruction fails
because it can't find /inc.php (which should have been /tmp/b/inc.php
instead).
The problem here is not the require(). It is that the CWD is converted
to the real path when, instead, it should remain the symlinked path.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

No, you did not read my initial post correctly:
a file/directory starting with a / (like /test1) means it is in the
root-directory. All example pathnames where absolute pathnames, not
relative.
Here comes my listing for you:
/htdocs/:
total 12
drwxr-xr-x 3 root root 4096 Dec 18 22:23 ./
drwxr-xr-x 22 root root 4096 Dec 18 22:23 ../
drwxr-xr-x 2 root root 4096 Dec 18 22:23 docs/
lrwxrwxrwx 1 root root 6 Dec 18 22:23 test2 -> /test1/
/htdocs/docs/:
insgesamt 8
drwxr-xr-x 2 root root 4096 18. Dez 22:23 ./
drwxr-xr-x 3 root root 4096 18. Dez 22:23 ../
-rw-r--r-- 1 root root 0 18. Dez 22:23 docs.inc.php
/test1/:
total 8
drwxr-xr-x 2 root root 4096 18. Dez 22:24 ./
drwxr-xr-x 22 root root 4096 18. Dez 22:23 ../
-rw-r--r-- 1 root root 0 18. Dez 22:24 index.php
Please note that test1 and test2 are not on the same directory level!

I don't realy understand your problem ?!

<?php
include("../docs/docs.inc.php");
echo "ok\n";
?>
[r...@pix sdv]# cat docs/docs.inc.php
<?php
echo "docs\n";
?>
No problem when i try this with apache :
http://www.xxxx.com/sdv/test1/index.php
http://www.xxxx.com/sdv/test2/index.php
==> same output : docs ok
if you try this in command line.
3 cases :
- pwd= test1 : php index.php => output docs ok
- pwd= test2 : php index.php => output docs ok
- pwd= anywhere else : php ./test1/index.php : include(): Unable to
access ../docs/docs.inc.php which is quite normal
the include path is relative to the current directory where php is
executed not relative to the php script which is executed ...
isn't it ?

This IS a bug: in Linux (and Unix like systems) beeing in a symlinked
directory should behave exactly like beeing in a directory with the same
content.
To use my example: If I use a shell and change to the folder
/htdocs/test2 (which is a symlink to /test1), ls ../docs/docs.inc.php
will show me the file "/htdocs/docs/docs.inc.php" and NOT
"/docs/docs.inc.php".
