No
v::no()
v::no(boolean $locale)
Validates if value is considered as "No".
v::no()->validate('N'); // true
v::no()->validate('Nay'); // true
v::no()->validate('Nix'); // true
v::no()->validate('No'); // true
v::no()->validate('Nope'); // true
v::no()->validate('Not'); // true
This rule is case insensitive.
If $locale
is TRUE, uses the value of nl_langinfo() with NOEXPR
constant.
