Req #63196 [NEW]: ReflectionMethod::invoke() on non-abstract ancestor

From: php dot net at vdachev dot net Operating system: Ubuntu Quantal PHP version: 5.4.7 Package: Reflection related Bug Type: Feature/Change Request Bug description:ReflectionMethod::invoke() on non-abstract ancestor Description: ------------ Consider a situation when an abstract class (or an interface) is defined and a concrete class that extends it. If we get instantiate a ReferenceClass object for the abstract class (or the interface), we can then get an ReferenceMethod instance for the abstract method. Unfortunately, calling the ReferenceMethod::invoke() method for an instance of the concrete class throws a ReflectionException ("Trying to invoke abstract method..."). Test script: --------------- <?php abstract class A { public abstract function doA(); } interface IB { function doB(); } class B extends A implements IB { public function doA() { echo 'A is done.'; } public function doB() { echo 'B is done.'; } } $b = new B(); $b->doA(); $b->doB(); $refA = new \ReflectionClass('A'); $refDoA = $refA->getMethod('doA'); $refDoA->invoke($b); $refIB = new \ReflectionClass('IB'); $refDoB = $refIB->getMethod('doB'); $refDoB->invoke($b); ?> Expected result: ---------------- The invocation of the method on an instance of the concrete class should succeed. Actual result: -------------- PHP Fatal error: Uncaught exception 'ReflectionException' with message 'Trying to invoke abstract method ...()' in ...:.. -- Edit bug report at https://bugs.php.net/bug.php?id=63196&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63196&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63196&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63196&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63196&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63196&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63196&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63196&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63196&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63196&r=support Expected behavior: https://bugs.php.net/fix.php?id=63196&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63196&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63196&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63196&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63196&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63196&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63196&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63196&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63196&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63196&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63196&r=mysqlcfg
