is_null__

Checks if a variable is null.

Works the same as PHP’s native is_null() function. If $var is not set, an Undefined variable notice will be thrown.

<?php

use function Qubus\Support\Helpers\is_null__;

is_null__(mixed $var): bool;

$var (mixed) (required) Variable to check.

(bool) Returns true if null, false otherwise.
