Description:
------------
I am searching for a proper php_rar.dll extension.

I have looked at http://snaps.php.net/win32/PECL_STABLE/
and found no php_rar.dll.

In the http://snaps.php.net/win32/PECL_UNSTABLE/ there
is a win32 version of php_rar.dll, but if i put it in
my extension dir and after including it to my extensions
in the php.ini there comes an error:

Unknown(): Invalid library (maybe not a php library) 'php_rar.dll'

Reproduce code:
---------------
download unstable version of php_rar.dll put in in the extensions directory, include it into php.ini restart apache 1.31

Expected result:
----------------
No error message ;-)

Actual result:
--------------
Unknown(): Invalid library (maybe not a php library) 'php_rar.dll'
