New Comment:
Although I can use a workaround for this problem (and in the meantime I
have), this is still a bug in php isn't it?
After using unset() on the array, in the loop, the reference breaks.

You are modifying array in the foreach loop.
Consider using for/while instead of foreach.
See this code:
<?php
$stuff = array('one','two');
foreach ($stuff as $key => &$value) {
$value='This should appear below in the var_dump() because $value
is passed by reference';
}
var_dump($stuff);
?>

- &$value is a refernce used in the foreach loop.
- If the unset is commented out, the reference to $stuff[1] as $value
on the second iteration of the loop works.
- The call to unset() on the first iteration breaks the reference
Actaul Output:
array(1) { [1]=> string(3) "two" }
Expected Output
array(1) { [1]=> string(3) "This should appear below in the var_dump()
because $value is passed by reference" }
<?php
$stuff = array('one','two');
foreach ($stuff as $key => &$value) {
if($key==0){
unset ($stuff[$key]);
}else{
$value='This should appear below in the var_dump() because $value
is passed by reference';
}
}
var_dump($stuff);
?>

What reference? Please give the _EXACT_ expected result.
(and shorten the example script..)

No, the bug is still present. The reference that should be present is
still broken.

So it's fixed and working -> closed.
