I also have this problem, in both Solaris 8 and Linux Mandrake with
Apache 1.2.27 with PHP 4.2.2, 4.2.3 and
also 4.3.0r2. In all cases the followig example does not work and php
complains about open_basedir restriction in
all but in 4.3.0r2, where the example does not work and no
warning or error message is issued.
You can reproduce this situation with 3 php scripts with safe_mode on:
/usr/local/http-docs/common/scripts/test.php --------------
<?php
include("test/test.php");
?>
/usr/local/http-docs/common/lib/test/test.php -------------
<?php
phpinfo();
echo "hello";
include("hello.php");
?>
/usr/local/http-docs/common/lib/test/hello.php -------------
<?php
echo "hello world";
?>
Apache configuration to reproduce the situation --------------
<Directory "/usr/local/http-docs/common/lib/">
Options none
AllowOverride None
Order allow,deny
Deny from all
</Directory>
Alias /scripts/ "/usr/local/http-docs/common/scripts/"
<Directory "/usr/local/http-docs/common/scripts/">
Options none
AllowOverride None
Order allow,deny
Allow from all
php_admin_value open_basedir
/usr/local/http-docs/common/scripts/:/usr/local/http-docs/common/lib
</Directory>
<VirtualHost 192.168.0.3>
ServerName 192.168.0.3
DocumentRoot /usr/local/http-docs/test
php_admin_value open_basedir
/usr/local/http-docs/test:/usr/local/http-docs/common/lib:/var/tmp:/usr/local/lib/php
php_admin_value doc_root /usr/local/http-docs/test
</VirtualHost>
to reproduce the error just go to http://192.168.0.3/scripts/test.php
altough phpinfo() on /usr/local/http-docs/common/lib/test/test.php
shows that open_basedir includes /usr/local/http-docs/common/lib
php fails to open hello.php

Looks like this bug is more serious than I thought. With
my workaround I get now randomly:
[24-Oct-2002 17:18:04] PHP Warning: Failed opening
'/include/banner.php' for inclusion (include_path='.') in
/www/doc/www.aaa.ch-80/wrapper.php on line 45
[24-Oct-2002 17:18:04] PHP Warning: Failed opening
'/include/services_2nd.inc' for inclusion (include_path='.') in
/www/doc/www.aaa.ch-80/wrapper.php on line 132
It really looks into the wrong dirs.
zend_get_executed_filename(TSRMLS_C) and path are not the
always the same.
Maybe this is a off by one error somewhere ?

Heh, now happens the opposite:
[24-Oct-2002 11:55:45] PHP Warning: open_basedir: File should be in
/www/doc/www.customer.ch-80, but is in
/www/doc/www.customer.org-80/photos/index.php file
(/www/doc/www.aaa.ch-80/formmail.php) in Unknown on line 0
I added now both cases. Works so far :P but doesn't solve
the real problem.

I'm using this workaround for now. It solves the
