Bug description: ReflectionClass::isInstantiable() returns true for abstract
classes
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
