--TEST--
Inherited static properties can be separated from their reference set.
--FILE--
<?php
class C { public static $p = 'original'; }
class D extends C { }
class E extends D { }
echo "\nInherited static properties refer to the same value across classes:\n";
var_dump(C::$p, D::$p, E::$p);
echo "\nChanging one changes all the others:\n";
D::$p = 'changed.all';
var_dump(C::$p, D::$p, E::$p);
echo "\nBut because this is implemented using PHP references, the reference set can easily be split:\n";
$ref = 'changed.one';
D::$p =& $ref;
var_dump(C::$p, D::$p, E::$p);
?>
==Done==
--EXPECTF--
Inherited static properties refer to the same value across classes:
%unicode|string%(8) "original"
%unicode|string%(8) "original"
%unicode|string%(8) "original"
Changing one changes all the others:
%unicode|string%(11) "changed.all"
%unicode|string%(11) "changed.all"
%unicode|string%(11) "changed.all"
But because this is implemented using PHP references, the reference set can easily be split:
%unicode|string%(11) "changed.all"
%unicode|string%(11) "changed.one"
%unicode|string%(11) "changed.all"
