Description:
------------
PHP documentation (http://www.php.net/file-exists) states that file_exists() function returns false, when file is inaccessible due to safe mode restrictions.

Tested PHP 4.3.10, 4.4CVS (200607021030), 5.1.4 and 5.2CVS(200607021030).

In PHP 5.1.4 and 5.2CVS file_exists() function returns true, when file exists, but is inaccessible due to safe mode restrictions. Other php versions work as documented.

Reproduce code:
---------------
<?php
var_dump(ini_get('safe_mode'));
var_dump(file_exists('/usr/games/fortune'));
var_dump(is_file('/usr/games/fortune'));
var_dump(is_dir('/usr/games/fortune'));
?>


Expected result:
----------------
When safe_mode is on
----
string(1) "1"
bool(false)
bool(false)
bool(false)
----

When safe_mode is off
----
string(0) ""
bool(true)
bool(true)
bool(false)
----

Actual result:
--------------
When safe_mode is on
----
string(1) "1"
bool(true)
bool(false)
bool(false)
----

When safe_mode is off
----
string(0) ""
bool(true)
bool(true)
bool(false)
----
