Traversal
=========

[](#traversal)

A service for hash map (assoc array) traversal.

When dealing with nested associative structures, traversing them can become quite a pain. Mostly because of the amount of `isset` checking that is necessary.

For example, to access a nested key `['foo']['bar']['baz']`, you must do something like this:

```
$baz = (isset($data['foo']['bar']['baz'])) ? $data['foo']['bar']['baz'] : null;
```

Enough already! `Traversal` provides a better way:

```
$baz = Gnugat\Traversal\get_in($data, array('foo', 'bar', 'baz'));
```

> **Note**: `Traversal` is a fork of [Igor](https://igor.io/)'s [get-in](https://github.com/igorw/get-in). which provides support for PHP 5.3.
