Flat to Hierarchy Sorter
========================

[](#flat-to-hierarchy-sorter)

Sorts flat list of nodes with IDs and parent IDs into layered list of nodes with IDs and lists of children to make iteration easier.

Example
-------

[](#example)

```
use WaughJ\FlatToHierarchySorter\FlatToHierarchySorter;
use WaughJ\FlatToHierarchySorter\HierarchicalNode;

$old_list =
[
    new HierarchicalNode( 1, 0 ),
    new HierarchicalNode( 2, 1 ),
    new HierarchicalNode( 3, 1 ),
    new HierarchicalNode( 4, 2 )
];
$sorted_list = FlatToHierarchySorter::sort( $old_list );

```

will return to equivalent of:

```
new HierarchicalNode
(
    1,
    0,
    [
        new HierarchicalNode( 2, 1, [ new HierarchicalNode( 4, 2 ) ] ),
        new HierarchicalNode( 3, 1 )
    ]
);

```
