Bug description: References to array keys
Description:
------------
It's possible to define a reference to a non-existent variable, which
gets assigned in a loop (example 1). It's possble to define a reference
to an existent key, too. Why is it not possible to define references to
non existent respective reference defined keys?
Reproduce code:
---------------
// Example 1:
$a = array (1, 2, 3);
$b = &$value;
foreach ($a as $value) {
echo $b;
}
// Example 2:
$a = array(array(1), array(2), array(3));
foreach ($a as $value) {
$b = &$value[0];
echo $b;
}
// Example 3:
$b = &$value[0];
foreach ($a as $value) {
echo $b;
}
Expected result:
----------------
123

Actual result:
--------------
