Confirmed in version 5.4.6
When using version 5.4.9, it appears to have been incidentally (or silently)
fixed.

Description:
The doc state that isset() is not a function, so that it can do weird things
like deep inspection, without raising a NOTICE about 'b' being undefined :
$a = array();
isset($a['b']['c']);
But if $a is an ArrayObject, the deep inspection does not work and a Undefined
index 'b' NOTICE is triggered.
But I found a __isset() in the documentation,
(http://www.php.net/manual/en/language.oop5.overloading.php#object.isset) it
have a very concise documentation but it seems a sufficient convention to make
this work :
I think that isset should call __isset() from left to right returning FALSE at
the 1st non set member, like this :
$a = SomeObject();
isset($a['b']['c']['d']['e']);
should call :
$a-__isset('b'), that should return FALSE, and stop here, wihout NOTICE.
Test script:
---
echo isset on array, work without notice\n;
$array = array();
var_dump(isset($array['a']['b']));
echo isset on arrayobject, should work as ArrayObject implements __isset\n;
$arrayobject = new ArrayObject();
var_dump(isset($arrayobject['a']['b']));
Expected result:
isset on array, work without notice
bool(false)
isset on arrayobject, should work as ArrayObject implements __isset
bool(false)
Actual result:
--
isset on array, work without notice
bool(false)
isset on arrayobject, should work as ArrayObject implements __isset
PHP Notice: Undefined index: a in test.php on line 10
Notice: Undefined index: a in test.php on line 10
bool(false)
