i have a list like this:

array(
  array(id=>100, parentid=>0, name=>'a'),
  array(id=>101, parentid=>100, name=>'a'),
  array(id=>102, parentid=>101, name=>'a'),
  array(id=>103, parentid=>101, name=>'a'),
)

but way bigger so i need a efficient way to make this into a tree like structure like this:

array(
  id=>100, parentid=>0, name=>'a', children=>array(
    id=>101, parentid=>100, name=>'a', children=>array(
      id=>102, parentid=>101, name=>'a',
      id=>103, parentid=>101, name=>'a',
    )
  )
)

i cannot use things like nested set or things like that becoas i can add left and right values in my database. any ideas?
