Description (last modified by SergeyBiryukov)

Reported by @djbu on ​support forums.

If a web host has the mbstring.func_overload PHP value set to something other than a numeric string (e.g. an empty string instead of the default '0' value), you'll see warnings like this in the error log:

PHP Warning: A non-numeric value encountered in .../wp-includes/functions.php on line 6746
PHP Warning: A non-numeric value encountered in .../wp-includes/pomo/streams.php on line 21

This is obviously an edge case, but we can easily avoid the warning by casting the value to (int) before checking.

In 51032:

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.
