New Comment:
Why is this bug closed? I din't see anywhere in the comment of
"unknown" that he tried to use an undefined index. And I suspect that
his example is incorrect, because var_dump($element) after assigning
return NULL.

I would like to say that this is a feature of PHP, and that it is
working as intended. Why?
This simple snippet explains it all:
<?php
$array = array(
'inner' => array(
'another' => array()
)
);
$element = &$array['inner']['another'][];
$element['test'] = 1;
$element['test2'] = 4;
?>
This functionality makes sense, at least in this context. You're
creating a new element, and getting it with the element reference.
This can make things easier and possibly faster to work with - instead
of this:
<?php
$array = array(
'inner' => array(
'another' => array()
)
);
$element['test'] = 1;
$element['test2'] = 4;
$array['inner']['another'][] = $element;
?>
Which is basically the same thing - just in a different order.
I don't think this is a bug, and if it were to be fixed it would cause
a lot of scripts - including ones I've written - to start generating
notices when they shouldn't be. (as I always try to write notice-less
code.)

Description:
------------
Accessing array with uninitialized index will normally trigger error:
$a=array();
$b=$a['unknown']; => undefined index error
but if I assign by reference:
$b=&$a['unknown'];
then PHP no longer throw error. (The same goes for assigning undefined
property to an object.)
This makes it difficult to debug scripts.
