Bug #44246 closedir() accepts a file resource opened by fopen()
Submitted: 2008-02-25 16:55 UTC Modified: 2008-07-22 14:12 UTC
From: Assigned: felipe
Status: Closed Package: Directory function related
PHP Version: 5.2CVS-2008-02-25 (CVS) OS: Windows XP
Private report: No CVE-ID:
 [2008-02-25 16:55 UTC]
closedir() will accept a file resource opened by fopen() as the $directory argument. In the documentation for closedir() it says the following: "The stream must have previously been opened by opendir()". It seems that the resource type is not being checked correctly. 
A directory opened with opendir() can also be passed to fclose() without an error message being generated.

Reproduce code:
var_dump($fp = fopen(__FILE__, 'r'));

$directory = dirname(__FILE__) . '/test';
var_dump($dh = opendir($directory));

Expected result:
resource(5) of type (stream)

Warning: closedir(): supplied argument is not a valid Directory resource in ...
resource(5) of type (stream)
resource(6) of type (stream)

Warning: fclose(): supplied argument is not a valid stream resource in ...
resource(6) of type (stream)

Actual result:
resource(5) of type (stream)
resource(5) of type (Unknown)
resource(6) of type (stream)
resource(6) of type (stream)
