Description:
------------
Trying to include or require a file containing '../' in its path fails with permission denied or file not found.

I've made sure that suhosin has not been loaded, and that safe mode is turned off while testing this, and can provide PHP's configure line and php.ini changes if needed.

This may to be related to closed bug #39351 (http://bugs.php.net/bug.php?id=39351).



Reproduce code:
---------------
File /www/included.php:
<?php echo 'Included ' ?>


File /www/a/index.php:
<?php
echo substr(sprintf('%o ', fileperms('/www/included.php')), -5);
include('/www/included.php');

echo substr(sprintf('%o ', fileperms('../included.php')), -5);
include('../included.php');
?>

Expected result:
----------------
When viewing file /www/a/index.php from a web browser:
0644 Included 0644 Included

When running PHP from the command line on /www/a/index.php:
0644 Included 0644 Included

Actual result:
--------------
From a web browser:
0644 Included 0644
Warning: include(../included.php) [function.include]: failed to open stream: Permission denied in /www/a/index.php on line 6

Warning: include() [function.include]: Failed opening '../included.php' for inclusion (include_path='.:/opt/php5/lib/php') in /www/a/index.php on line 6


From the command line:
0644 Included

Warning: fileperms(): stat failed for ../included.php in /www/a/index.php on line 5

Warning: include(../included.php): failed to open stream: No such file or directory in /www/a/index.php on line 6

Warning: include(): Failed opening '../included.php' for inclusion (include_path='.:/opt/php5/lib/php') in /www/a/index.php on line 6
