The user comments on the array_unique page do shed some light on this. You will most likely find some hidden gems in those comments - its a very handy documentation.

Just a quick browser through revealed the following to remove duplicates from a multi dimensional array:

function super_unique($array)
  $result = array_map("unserialize", array_unique(array_map("serialize", $array)));

  foreach ($result as $key => $value)
    if ( is_array($value) )
