A very flexible data-structure (inspired by Ruby's `ostruct` library)

Requirements
------------

[](#requirements)

This library requires PHP 5.4+

Installation
------------

[](#installation)

You can easily install `Open_Struct` with the following command:

```
composer [global] require 'jzaleski/php-open_struct=*'

```

Usage
-----

[](#usage)

Creating a new \[empty\] instance:

```
$struct = new Open_Struct;
```

Creating a new instance from an array of attributes:

```
$struct = new Open_Struct(['foo' => 1, 'bar' => ['biz' => 2]]);
```

Dereferencing a top-level value:

```
$value = $struct->foo;
```

Getting a top-level value by index/key:

```
$value = $struct['foo'];
```

Dereferencing a nested value:

```
$nested_value = $struct->bar->biz;
```

Getting a nested value by index/key:

```
$nested_value = $struct['bar']['biz'];
```

Setting a top-level value:

```
$struct->foo = 2;
```

Setting a top-level value by index/key:

```
$struct['foo'] = 2;
```

Setting a nested value:

```
$struct->bar->biz = 3;
```

Setting a nested value by index/key:

```
$struct['bar']['biz'] = 3;
```

Unsetting a top-level value:

```
unset($struct->foo);
```

Unsetting a top-level value by index/key:

```
unset($struct['foo']);
```

Checking for the existence of a key:

```
isset($struct->foo);
```

Checking for the existence of a key by index/key:

```
isset($struct['foo']);
```

Setting a callback value (this is useful for scenarios where you want to derive or lazy-load a property):

```
$dao = new Data_Access_Object;

$struct = new Open_Struct(['something' => function() use ($dao) { return $dao->get_something(); }]);

$struct->something;
```

The `dirty` method will return `false` until initialization (the constructor) is complete:

```
$struct = new Open_Struct(['foo' => 1]);

$struct->dirty(); // returns: `false`
```

The `dirty` method will return `true`, after initialization (the constructor), when a value is set:

```
$struct = new Open_Struct;

$struct->foo = 1;

$struct->dirty(); // returns: `true`
```

The `dirty` method will return `false`, after initialization (the constructor), when a value is set back to its original state:

```
$struct = new Open_Struct(['foo' => 1]);

$struct->foo = 2;

$struct->dirty(); // returns: `true`

$struct->foo = 1;

$struct->dirty(); // returns: `false`
```

Getting the array of attributes:

```
$struct = new Open_Struct(['foo' => 1]);

$struct->foo = 2;

$struct->bar = 3;

$struct->attributes(); // returns: `['foo' => 2, 'bar' => 3]`
```

Getting the array of changed attributes:

```
$struct = new Open_Struct(['foo' => 1]);

$struct->bar = 2;

$struct->changed_attributes(); // returns: `['bar' => 2]`
```

The `changed_attributes` method will return an empty array. after initializaiton (the constructor), when a value is set back to its original state:

```
$struct = new Open_Struct(['foo' => 1]);

$struct->foo = 2;

$struct->changed_attributes(); // returns: `['foo' => 2]`

$struct->foo = 1;

$struct->changed_attributes(); // returns: `[]`
```
