Bug description: is_callable returns true even if method does not exist in
parent class
Description:
------------
is_callable returns "true" for methods that are not present in the parent
class, but in the child class, even if you use the "parent" keyword.
Earlier php versions correctly returned false, since the method is missing
in the parent class.
Perhaps it has something to do with the changes in conjunction with late
static binding.
Reproduce code:
---------------
<?php
class ParentClass {
}
class ChildClass extends ParentClass {
public function testIsCallable() {
var_dump(is_callable(array($this, 'parent::testIsCallable')));
}
}
$child = new ChildClass();
$child->testIsCallable();
?>
Expected result:
----------------
bool(false)
Actual result:
--------------
bool(true)
