@PHPychoauthorFeb 25.2008 — Thanks i got it working by performing as:

[code=php]$element = '';
foreach ($array as $obj){
$element .= '->'.$obj;
}
$element = trim($element, "->");

eval('$return = $this->'.$element.';');

return $return;[/code]

@ZnupiFeb 25.2008 — Here's a better alternative, since eval() isn't that good:
[code=php]
$array = Array("parent", "child1", "child2");
class emptyclass {

}
$object = new emptyclass();
$temp = $object;
foreach ($array as $element) {
$temp->$element = new emptyclass();
$temp = $temp->$element;
}
print_r($object);
[/code]

Success!
