From: graced at monroe dot wednet dot edu Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: instanceof documentation & inheritance
Description:
------------
The documentation for the instanceof operator in the manual does not
authoritatively say that the operator checks parent classes and interfaces
as well as the base clase, i.e.
class A { }
class B extends A { }
$thing = new B;
if ($thing instanceof A) {
echo 'A';
}
if ($thing instanceof B) {
echo 'B';
}
// result: AB
?>
