Summary: unset failes with ArrayObject and deep arrays
Status: Open

New Comment:
It's worse than this, ArrayObject gets confused on where to put the data
and mangles any containing object:
test script:
class IWouldLikeToPointOutABug {
}
$buggy = new IWouldLikeToPointOutABug();
$buggy->bug = new ArrayObject( );
$buggy->bug['foo']['bar'] = true;
echo "This looks normal\r\n";
var_dump( $buggy );
echo "This should be NULL\r\n";
var_dump( $buggy->thisIsNotHere );
Results in:
This looks normal
object(IWouldLikeToPointOutABug)#1 (1) {
["bug"]=>
object(ArrayObject)#2 (0) {
}
}
This should be NULL
array(1) {
["bar"]=>
bool(true)
}

Description:
------------
Using deep arrays unset itself or ArrayObject misbehaves. It silently
does nothing.
The problem lies in iteration 3 that mixes ArrayObject and classic
arrays.
Test script:
---------------
echo "iteration1\n";
$arr = new ArrayObject();
$arr['foo'] = new ArrayObject();
$arr['foo']['bar'] = true;
unset($arr['foo']['bar']);
var_dump($arr);
echo "iteration2\n";
$arr = array();
$arr['foo']['bar'] = true;
unset($arr['foo']['bar']);
var_dump($arr);
echo "iteration3\n";
$arr = new ArrayObject();
$arr['foo']['bar'] = true;
unset($arr['foo']['bar']);
var_dump($arr);
Expected result:
----------------
iteration1
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(1) {
["foo"]=>
object(ArrayObject)#2 (1) {
["storage":"ArrayObject":private]=>
array(0) {
}
}
}
}
iteration2
array(1) {
["foo"]=>
array(0) {
}
}
iteration3
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(1) {
["foo"]=>
array(0) {
}
}
}
Actual result:
--------------
iteration1
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(1) {
["foo"]=>
object(ArrayObject)#2 (1) {
["storage":"ArrayObject":private]=>
array(0) {
}
}
}
}
iteration2
array(1) {
["foo"]=>
array(0) {
}
}
iteration3
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(1) {
["foo"]=>
array(1) {
["bar"]=>
bool(true)
}
}
}
