PHP Subtypes

[qkdreyer]

Describe the bug
Subtypes appears to be not supported
https://www.php.net/manual/en/class.reflectiontype.php

To Reproduce

<?php

$reflectionClass = new \ReflectionClass($this);
$reflectionMethods = $reflectionClass->getMethods();
$reflectionMethod = \current($reflectionMethods);
$reflectionParameters = $reflectionMethod->getParameters();
$reflectionParameter = \current($reflectionParameters);
$reflectionType = $reflectionParameter->getType();
$reflectionType->getName();

Expected behavior
$reflectionType should be typed hinted to \ReflectionNamedType|\ReflectionUnionType|null, not \ReflectionType|null

Screenshots

Platform and version

• macOS 12.1
• intelephense v1.8.0

The manual seems to type hint ?ReflectionType. I believe intelephense uses that information.

Closing as I think it is the same as #2094 . There's a bug here determining return types for specific php versions.
