I think you don't understand me.
In which directory are you in when executing a script ?
The directory where the symlink is or the directory where the
original file is ?
Well, depending if the path goes backwards or not (with two
dots '..') the path to calculate a relative path is one or the other.
Do you understand me ?
require("dir/include.php"); loads /var/php/scripts/dir/include.php
while require("../dir/include.php"); loads /var/www/dir/include.php.
They're calculated from diferet base paths, please, take a look at
the example I gave, exactly at the paths, there is where the
problem is. One path is calculated from where the file is, and the
other path is calculated from where the symlink is, and the only
diference between both paths is the '..'. To give you a better
example.
Original script: /var/php/scripts/index.php
Symlink: /var/www/htdocs/index.php -> ../../php/scripts/index.php
Acording to what you say (which makes sense to me) this two
lines should include the same file:
require("include.php");
require("../scripts/include.php");
right ?
well, the first one fill succesfully include
/var/php/scripts/include.php
while the second one will include
/var/www/scripts/include.php (because this path instead of
being /var/php/scripts/../scripts/include.php is
/var/www/htdocs/../scripts/include.php) It is resolved from the
location of the symlink and not the original file.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
When including a file, it is included based on the directory you are
currently in. If that directory was /var/php/scripts/ , then all
relative paths will be calculated based on that directory.

I don't have a 'working' on line example to show you this and I
don't have posibilities to do it right now, I'm sorry, but I'll try to
show you here what I mean with an example.
Let's supouse I have one script in this file
/var/php/scripts/index.php
and I have a symlink to that file like this
/var/www/htdocs/index.php -> ../../php/scripts/index.php
and this file contains the following:
<?php
require("dir/include.php");
require("../dir/include.php");
?>
When I run it, for require("dir/include.php"); it tryes to include
/var/php/scripts/dir/include.php (the relative path from the
original location of the file) but for require("../dir/include.php");
it
tryes to icnlude /var/www/dir/include.php (real path for
/var/www/htdocs/../dir/include.php) (it is resolving the relative
path from the symlink and not the original file).
I'm not sure with behaviour is the right one, but this mix is not
the right one for sure, I think.
I hope it helps, if you need more help, just contact me.
Thank you.

Could you show an example of what you mean?

I'm requesting a page, the file that is called is
index.php, but this file is a symlink from somewhere else.
When I require a file from index.php, if there's no '..'
(dots) on the path (a relative path, but not going back),
the relative path is from where the original file is, but
if there are '..' on the path, the relative path is
from where the symlink is (although php identifies the
script as the original file in the error message).
