ID: 40223 Updated by: vrana@php.net Reported By: baldurien at bbnwn dot eu -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: * PHP Version: * New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. class ReflectionFunction extends ReflectionFunctionAbstract implements Reflector { } class ReflectionMethod extends ReflectionFunctionAbstract implements Reflector { } Previous Comments: ------------------------------------------------------------------------ [2007-01-24 20:23:50] helly@php.net Method and Functions are in no way derived. Thus the following design approach was taken: class ReflectionMethod extends ReflectionFunctionAbstract implements Reflector class ReflectionFunction extends ReflectionFunctionAbstract implements Reflector ------------------------------------------------------------------------ [2007-01-24 19:47:02] tony2001@php.net The documentation is wrong, both ReflectionMethod & ReflectionFunction extend abstract class called "ReflectionFunctionAbstract". ------------------------------------------------------------------------ [2007-01-24 19:46:19] bjori@php.net (reclassified as documentation problem) The docs are wrong (and really outdated). ReflectionMethod and ReflectionFunction both extend ReflectionFunctionAbstract. (see: php --rc ReflectionMethod && php --rc ReflectionFunction or php --re reflection) ------------------------------------------------------------------------ [2007-01-24 19:39:00] baldurien at bbnwn dot eu Description: ------------ The doc (http://fr.php.net/manual/en/language.oop5.reflection.php) state that ReflectioMethod be a ReflectionFunction. class ReflectionFunction implements Reflector { } class ReflectionMethod extends ReflectionFunction { } But this is not how it works in PHP : when using type hinting, any ReflectionMethod passed to a function or method that expect a ReflectionFunction fails instead of working like with normal type hinting. Reproduce code: --------------- class Foo { public function bar(ReflectionFunction $fct) { ... } } $c = new ReflectionClass('Foo'); $foo = new Foo(); $foo->bar($c->getMethod('bar')); Expected result: ---------------- This should work because ReflectionMethod is a sub class of a ReflectionFunction, and type hinting normally allows such thing (or the documentation [http://fr.php.net/manual/en/language.oop5.typehinting.php] should say it clearly...) Actual result: -------------- [E_RECOVERABLE_ERROR] Argument 1 passed to Foo::bar() must be an instance of ReflectionFunction, instance of ReflectionMethod given, called in ... on line ... and defined' in ... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40223&edit=1
