array-access: A PHP repository from appkr

Note

This project is just for STUDY PURPOSE. In reality, there is no reason or benefit to use this over simple (array) casting.

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:

Say, the following Data class is our DTO.

// example/Data.php

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

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']);

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

That's it.

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
