New Comment:
This is exactly according to the documentation:
If FILTER_NULL_ON_FAILURE is set, FALSE is returned only for "0",
"false", "off", "no", and "", and NULL is returned for all non-boolean
values.
Note that "false" is in the list, but false is not. That is, the string
"false" will give a result, the boolean false will return null.
"Non-boolean" makes this a little bit confusing.
Note that the goal here is to convert a string to a boolean. Because
false is not a string, filter_var does not consider it valid input.
