Bug #79804 [Opn]: Reflection doesn't know about DateInterval and DatePeriod properties

Edit report at https://bugs.php.net/bug.php?id=79804&edit=1 ID: 79804 Updated by: nikic@php.net Reported by: ondrej at mirtes dot cz Summary: Reflection doesn't know about DateInterval and DatePeriod properties Status: Open Type: Bug Package: Reflection related PHP Version: 8.0.0alpha1 Block user comment: N Private report: N New Comment: We may be able to address some cases though, for example I don't see any reason why LibXMLError doesn't have declared properties -- it doesn't seem to be doing anything magic. Previous Comments: ------------------------------------------------------------------------ [2020-07-07 15:29:34] nikic@php.net 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. ------------------------------------------------------------------------ [2020-07-07 15:13:21] ondrej at mirtes dot cz The actual result is empty: https://3v4l.org/68832 ------------------------------------------------------------------------ [2020-07-07 15:12:41] ondrej at mirtes dot cz 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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79804&edit=1
