#34299 [Fbk->Asn]: ReflectionClass::isInstantiable() returns true for abstract classes

ID: 34299 Updated by: helly@php.net Reported By: dennis at inmarket dot lviv dot ua -Status: Feedback +Status: Assigned Bug Type: Class/Object related -Operating System: WinXP +Operating System: * -PHP Version: 5.1.0RC1 +PHP Version: 5.0.4 -Assigned To: +Assigned To: helly Previous Comments: ------------------------------------------------------------------------ [2005-08-29 23:33:24] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2005-08-29 23:16:21] dennis at inmarket dot lviv dot ua Description: ------------ ReflectionClass::isInstantiable() returns true for abstract classes. Of course, subsequent call to ReflectionClass::newInstance() fails. Please note: this is not the same as bug #28895 (which claims to be solved) - that bug submitter stressed that isAbstract always returns false. In this case, isAbstract returns true, but the isInstantiable also returns true. Reproduce code: --------------- <? abstract class X {} $rc = new ReflectionClass('X'); echo $rc->isAbstract() ? 'yes' : 'no', "\n"; if($rc->isInstantiable()) { echo "Class X is instantiable"; $x = $rc->newInstance(); } else { echo "Cannot instantiate abstract class"; } ?> Expected result: ---------------- yes Cannot instantiate abstract class Actual result: -------------- yes Class X is instantiable Fatal error: Cannot instantiate abstract class X in /path/to/abstract.php on line 9 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34299&edit=1
