mb_convert_case undefined function (Symfony2 FOS/UserBundle)

问题

On my Symfony2 application, I am receiving an error:

Fatal error: Call to undefined function FOS\UserBundle\Util\mb_convert_case() in /Applications/MAMP/htdocs/application/vendor/bundles/FOS/UserBundle/Util/Canonicalizer.php on line 18

I am using PHP 5.3.6.

Here is my PHPInfo showing that mbstring is enabled:

If mbstring is enabled then why is mb_convert_case not being found?

I found this:

Under Windows you must uncomment the line with php_mbstring.dll in your php.ini

I don't know if you're running a windows box or not.
