Description:
------------
commands like require('../somefile') fail although they didn't in versions prior to 5.2.0. This happens when the user running the command does not have 'r' rights to the directory of the included file. Bug #39351 seems related but it is supposedly closed.

Reproduce code:
---------------
cd tmp
umask 022
mkdir d1
chmod 711 d1
cd d1
echo Included > fin.php
mkdir d2
cd d2
echo '<? require("/tmp/d1/fin.php") ?>' > f.php
echo '<? require("../fin.php") ?>' >> f.php
php /tmp/d1/d2/f.php


Expected result:
----------------
Included
Included

Actual result:
--------------
Included

Warning: require(../fin.php): failed to open stream: Permission denied in f.php on line 2

Fatal error: require(): Failed opening required '../fin.php' (include_path='.:/opt/php/lib/php') in f.php on line 2
