Comment (by hellofromTonya):

 @wppunk As documented, `sanitize_key()` expects the key given to be a
 string data type. The data type check is part of the input validation to
 ensure the incoming value is of string before passing it to native PHP
 functions that expect and require a string value.

 Question: Can you share the use case where an integer value needs to be
 sanitized?
