Description:
------------
The array_search function works fine when searching through regular arrays, but when you try to search with it from an array made with file(), it doesn't find anything.

Reproduce code:
---------------
example.list:
1
2
3
4
5

bug.php:
<?
        $list = file('example.list');
                                                                                
        print array_search('2', $list);
?>

Expected result:
----------------
1

Actual result:
--------------
<nothing>
