mb_convert_case undefined function (Symfony2 FOS/UserBundle)

mamp, mbstring, php, symfony

Solution

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.

Problem

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: https://i.stack.imgur.com/FCMDv.png If mbstring is enabled then why is mb_convert_case not being found?
