Installation

------------

If you use Packagist for installing packages, then you can update your composer.json like this :

``` json

{

    "require": {

        "sweelix/tree": "*"

    }

}

```

Howto use it

------------

Create a Node class and attach the NodeTrait to it. You can look at the class ```Node```.

``` php

use sweelix\tree\NodeTrait;

class MyNode {

    use NodeTrait;

}

```

Now you can create a node :

``` php

$node = new MyNode();

$node->setPath('1.2.1');

$leftBorder = $node->getLeft();

$rightBorder = $node->getRight();

$treeInfo = $node->getMatrix()->toArray();

// insert your node in DB using leftBorder and rightBorder

// do not forget to also store the tree info

```

Now you can search the node in your DB using regular nested set methods :

```sql

# find all the children

select * from nodes where left > :nodeLeft and right < :nodeRight order by nodeLeft;

# find all the parents

select * from nodes where left < :nodeLeft and right > :nodeRight order by nodeRight;

```
