array unique(array $array);
Sorts an array of DOM nodes based on document position, in place, with the duplicates removed. Note that this only works on arrays of DOM nodes, not strings or numbers.
$fd = new FluentDOM\Nodes(
'<items><one/><two/><three/></items>'
);
$list = array_merge(
$fd->find('/items/*')->toArray(),
$fd->find('//*')->toArray()
);
var_dump(count($list), count($fd->unique($list)));
int(7)
int(4)
