Summary: ReflectionFunction:getReturnType returns
ReflectionNamedType object.
Status: Open
Type: Documentation Problem
Package: Reflection related
Operating System: Linux
PHP Version: 7.1.0RC5
Block user comment: N

New Comment:
The documentation is correct -- we only guarantee that a ReflectionType is returned.
ReflectionNamedType is a specific ReflectionType. In the future it might also return something like
ReflectionUnionType (another specific ReflectionType).
Return types do not specify that *exactly* that class will be returned, only that it's that
class or a subtype. Right now it will always be ReflectionNamedType, but this is not guaranteed, by
design.

Description:
------------
In 7.1.0beta3 ReflectionNamedType was introduced, documentation not updated.
The original ReflectionType is not instantiated anymore.
https://github.com/php/php-src/commit/622d2f41d1cdb597f4fafecaaacf66e238742bd4
I don't think this class change is intentional, this would be an even bigger BC break than the
discussed ReflectionType::__toString change discussed on internals: http://externals.io/thread/321
Testscript @ See https://3v4l.org/Pmu6c#v710beta3
Test script:
---------------
<?php
class B
{
public function test(): B
{
}
}
function getB(): B
{
}
$rc = new ReflectionMethod('B', 'test');
var_dump((string)$rc->getReturnType(), $rc->getReturnType());
$rc = new ReflectionFunction('getB');
var_dump((string)$rc->getReturnType(), $rc->getReturnType());
Expected result:
----------------
string(1) "B"
object(ReflectionType)#2 (0) {
}
string(1) "B"
object(ReflectionType)#1 (0) {
}
Actual result:
--------------
string(2) "\B"
object(ReflectionNamedType)#2 (0) {
}
string(2) "\B"
object(ReflectionNamedType)#1 (0) {
}
