Bug description:offsetGet not used for non existed items with second level of
depth (and more)
Description:
------------
If you overload offsetGet method, and return array from it, on non existed
keys/offset, test script must works without warnings.
Maybe because offsetGet not used, or PHP interpreter parse it from
right-to-left,
something like this (pseudo code):
1. $t = foo->bar = 1
2. $a = $t;
Test script:
---------------
<?
error_reporting(E_ALL);
class OnEmptyArray extends ArrayObject {
/**
* Create ArrayObject on not existed offsets/keys
*/
public function offsetGet($offset) {
if (!$this->offsetExists($offset)) {
$this->{$offset} = new self(array(), $this->getFlags(),
$this->getIteratorClass());
}
return parent::offsetGet($offset);
}
}
echo "Begin\n";
$a = new OnEmptyArray();
$a->foo->bar = 1;
echo "End\n";
Expected result:
----------------
Begin
End
Actual result:
--------------
Begin
PHP Warning: Creating default object from empty value in - on line 20
End
