When using strict types, null is often erased when casting, introducing subtle bugs. This library allows you to replace your casts with these simple functions that retain null, but otherwise perform the desired cast.

Installation

composer require withinboredom/null-cast

Usage

use function Withinboredom\NullCast\boolval;
use function Withinboredom\NullCast\floatval;
use function Withinboredom\NullCast\intval;
use function Withinboredom\NullCast\stringval;

boolval('true') === true;
boolval(null) === null;

floatval('12.34') === 12.34;
floatval(null) === null;

intval(true) === 1;
intval(null) === null;

stringval(123) === '123';
stringval(null) === null;
