Message:

General: Avoid a PHP warning when checking the mbstring.func_overload PHP value.

This avoids "A non-numeric value encountered" warning when mbstring.func_overload is set to something other than a numeric string, e.g. an empty string instead of the default '0' value.

Props djbu.
Fixes #53282.
