As @TomaszKane said in comment, mb_strlen() is native PHP function, so you need to call it as mbstrlen() without specifying the namespace.

Official documentation:

Also take a look at yii\helpers\StringHelper, mb_strlen() is used in several places. For example, if you are looking for byte length, there is special method byteLength(), you can call it like that:

use yii\helpers\StringHelper;

...

StringHelper::byteLength($string);

It's basically syntactic sugar of mb_strlen().
