Bug #34299 ReflectionClass::isInstantiable() returns true for abstract classes
Submitted: 2005-08-29 23:16 UTC Modified: 2005-08-30 09:39 UTC
From: dennis at inmarket dot lviv dot ua Assigned: helly (profile)
Status: Closed Package: Class/Object related

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:
Cannot instantiate abstract class

Actual result:
Class X is instantiable
Fatal error: Cannot instantiate abstract class X in /path/to/abstract.php on line 9
