function get_parents($id){
if(!isset($this->categories[$id])) return array();

$p = $this->categories[$id]['fup'];
$ps = array();
while($p){
array_unshift($ps, $this->categories[$p]);
unset($ps[0]['categories']);
$p = $this->categories[$p]['fup'];
}
return $ps;
}

1、这段话什么意思？
2、还有一个字段“ffup”与“fup”是或的关系，我想修改这段代码：如果是“ffup”与“fup”都可以，都要调用，该怎么改？

if(isset($v['categories']))
$ids = $ids + $this->get_children_ids($v['fid']);
}

return $ids;
}
