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.
