 New Comment:

I'm not willing to address this unless either a) those become normal properties or b) we get
first-class accessor support, and those properties become accessors.

For now, the right way to think about them is like properties implemented through __get(), which is
effectively what these are, just on the internal layer.

Description:
------------
There isn't any PHP version that would know about properties coming from classes like
DateInterval and DatePeriod. I think that PHP 8 is a great opportunity to fix this.

There are also other classes with the same problem, mainly coming from ext-dom. Here's a list
of how I compensated for that in PHPStan: https://github.com/phpstan/phpstan-src/blob/069ffbbece0323a1a22557f41237d4b9efd6c521/src/Reflection/PhpDefect/PhpDefectClassReflectionExtension.php

Test script:
---------------
<?php

$ref = new \ReflectionClass(\DateInterval::class);
foreach ($ref->getProperties() as $property) {
    var_dump($property–>getName());
}

$ref = new \ReflectionClass(\DatePeriod::class);
foreach ($ref->getProperties() as $property) {
    var_dump($property–>getName());
}

Expected result:
----------------
Dumped list of properties from:

https://www.php.net/manual/en/class.dateinterval.php
https://www.php.net/manual/en/class.dateperiod.php
