My understanding is only one scalar type should exist.
From the RFC:
https://wiki.php.net/rfc/scalar_type_hints_v5
Heading: "Type Aliases Should Not Be Supported"
> This proposal takes the stance that there should be one obvious type. Therefore, no aliases are
> supported.
I cannot remember a separate RFC to reserve boolean (or integer for that matter) for use.

Description:
------------
You can cast to boolean using either (bool)$var or (boolean)$var. In scalar type hints currently
only bool could be used which is inconsistent.
Test script:
---------------
<?php
$boolean = 1;
$boolean = (boolean) $boolean;
function dump_boolean(boolean $var)
{
var_dump($var);
}
dump_boolean($boolean);
// https://3v4l.org/Cdtoe
Expected result:
----------------
I'd expect both boolean and bool work as scalar type hint because both work well for type
casting.
Actual result:
