Description:
------------
When open_basedir set file_exists() raise an open_basedir warning 
when checking a path which permitted by open_basedir but includes 
an existent file misused as directory.


Test script:
---------------
//create a file
$fhandle = fopen('existing-file-which-is-not-dir.txt', 'w');

//throw your mind away and use it as a directory
if (is_file('existing-file-which-is-not-dir.txt/test.html')) {
        print "File exists";
} else {
        print "File does not exist";
}

//show the error
print_r(error_get_last());

Expected result:
----------------
is_file should return a FALSE and you should read "File does not exist".

Actual result:
--------------
In addition to "File does not exist", you'll get a warning that 
open_basedir restriction is in effect:

- bug 52065 "Warning about open_basedir restriction while accessing a file as 
directory"
- bug 53041 "is_file() and open_basedir" closed to due no feedback (@pajoye: yes)

tl;dr: bug is not about open_basedir itself but rather some code being unable to 
access the file (rightly so) and the calling code assuming the failure is because 
of open_basedir.

File functions produce warning if argument is a path which starts with existing file.

<?
touch('./index.php');
ini_set('open_basedir', '.');
var_dump(file_exists('./index.php/.section.php'));
?>

Expected result: 
bool(false)

Actual result: 
Warning: file_exists(): open_basedir restriction in effect. File(./index.php/.section.php) is not within the allowed path(s): (.) in ***/1.php on line 4
bool(false)

OS FreeBSD.
