Bug #72220 [NEW]: Loose anonymous class comparison inconsistency
From: remyfox at hotmail dot com
Operating system: Windows
PHP version: 7.0.6
Package: Class/Object related
Bug Type: Bug
Bug description:Loose anonymous class comparison inconsistency
Description:
------------
When two new anonymous class instances are returned from a function,
then they are equal. When they are instantiated and directly compared,
then they are unequal. Comparison happens with the == operator.
Test script:
---------------
// Returns false.
var_dump(new class{} == new class {});
$a = function() {
return new class{};
};
function b() {
return new class{};
}
// Returns true.
var_dump($a() == $a());
// Returns true.
var_dump(b() == b());
