EArray is a small PHP class to provide convenient ways to access a PHP array.

- Convenient accessing to a nested array.
- You can use a default value when you try to get a value of array.
- You can use this object as a normal array (Implementing `ArrayAccess`, `Iterator` and `Countable` interfase).
- It has some convenient methods for array: `each`, `filter`, `sort`.
- You can register custom methods to array.

It aims to remove code that checks array key existence. Especially for a nested array. Do you hate the code like the below?

```
$val = null;
$arr2 = isset($arr["key"]) ? $arr["key"] : null;
if (is_array($arr2)) {
    $val = isset($arr2["key2"]) ? $arr2["key2"] : null;
}

echo $val;
```

You can write same things using EArray object.

```
echo $earray->get("key/key2", null);
```
