Quick Installation
------------------

[](#quick-installation)

```
composer require danielcosta/tree
```

Usage
-----

[](#usage)

To use, just get an array like bellow

```
$flatArray = [
    [
        'id' => 1,
        'name' => 'Level 1',
        'parentId' => 0,
        'nodes' => [],
    ],
    [
        'id' => 3,
        'name' => 'Level 3',
        'parentId' => 2,
        'nodes' => [],
    ],
    [
        'id' => 2,
        'name' => 'Level 2',
        'parentId' => 1,
        'nodes' => [],
    ],
];
```

And pass it to the helper `Tree`, using `Tree::makeFromFlatArray($flatArray);`. The result will be exactly this:

```
$result = Tree::makeFromFlatArray($flatArray);
print_r($result);
/*
Array
(
    [id] => 1
    [name] => Level 1
    [parentId] => 0
    [nodes] => Array
        (
            [0] => Array
                (
                    [id] => 2
                    [name] => Level 2
                    [parentId] => 1
                    [nodes] => Array
                        (
                            [0] => Array
                                (
                                    [id] => 3
                                    [name] => Level 3
                                    [parentId] => 2
                                    [nodes] => Array
                                        (
                                        )
                                )
                        )
                )
        )
)
*/
```

Optional parameters to this method are:

- $parentId = 0 - when you want to set the first level of the return
- string $key = 'id' - the primary key on your flat array
- string $parentKey = 'parentId' - the parent key on your flat array
- string $childKey = 'nodes' - where to put the child nodes
