Thanks! It nearly worked. But the last element was always added as

[last] => array ( 'last' => 'value')

instead of just 'last' => 'value'
because the else condition gets hit with every last element.
So I added a condition so the last iteration will not process
the 'else'. It looks like that in my code:

        foreach ($keys as $i => $k) {
                if (isset($arr[$k]))
                                $arr = &$arr[$k];
                else {
                        if ($i < count($keys)-1) {
                                $arr[$k] = '';
                                $arr = &$arr[$k];
                        }
                }
        }

I am working on a PmWiki recipe for processing multi-dimensional
arrays or data trees.
