Description:
------------
PHP version (as given in phpinfo()): PHP Version 5.3.3-1ubuntu9.3

Zip-related information:
Zip 	enabled
Extension Version 	$Id: php_zip.c 300470 2010-06-15 18:48:33Z pajoye $
Zip version 	1.9.1
Libzip version 	0.9.0 

Test script:
---------------
function testReturnValue() {
        $extractToPath = "/home/user/testDir"; /* existing dir with NO write privileges */
        $zipPath = "path/to/zipFile"; // has to be valid zip file

        $zip = new ZipArchive();
        $open = $zip->open($zipPath);
        if ($open === true) {
           $extracting = $zip->extractTo($extractToPath);
           $zip->close();
           return $extracting;
        } else {
           return false;
        }
}

Expected result:
----------------
Return value of testReturnValue() should be FALSE, as long as the php user has no write access to the directory into which we extract the zip (because if that's the case, nothing will happen).

Actual result:
--------------
Return value is TRUE, even if no extracting happened due to lacking privileges.
