ArrayAccess Example

Appkr\ValueArray.php comes in handy when we want to access property value of DTO(Data Transfer Object) using array syntax.

For example:

Our DTO

Say, the following Data class is our DTO.

// example/Data.php

class Data
{
    public $a = 'foo';
    public $b = 'bar';
    public $c = 'baz';
}

What We Want To Do With The DTO Is...

Assume that the following is our domain code.

// example/client.php

$dto = new Data;
$arr = new Appkr\ValueArray(new Data);
var_dump($dto->a);
var_dump($arr['a']);

The Execution Result Will Be...

$ php example/client.php
# example/client.php:8:
# string(3) "foo"
# example/client.php:9:
# string(3) "foo"

That's it.

Install

This component is not listed on the packagist (yet). So we have to add a repositories section in composer.json.

// composer.json

"repositories": [
  {
    "type": "vcs",
    "url": "https://github.com/appkr/array-access.git"
  }
],

And then,

$ composer install
