README

PHP likes to send data back as strings when pulling from datasources. This library will help you convert everything into a native php format.

Example

The easiest way to learn about this library is to see an example. We'll pretend that we are converting a row from a database.

The property map is an array of 'property name' => 'mapping name' pairs. See the Casting section for more information on what is available.

class UserObject extends Wid\Data\NativeObject
{
	protected function init()
	{
		$this->setPropertyMap(array(
			'id' => 'Integer',
			'active' => 'Boolean',
			'joined_at' => 'DateTime',
			'roles' => function($arg){
				return explode(',', $arg);
			}
		));

		parent::init();
	}
}

$databaseRow = array(
 	'id' => '1',
	'username' => 'dwidmer',
 	'active' => '0',
 	'joined_at' => '2014-01-15 12:00:00',
	'roles' => 'super,admin,user'
);

$user = new UserObject($databaseRow);
$user->toArray();

/* //// Output //// */

// 'id' => (int) 1
// 'username' => (string) 'dwidmer'
// 'active' => (boolean) false,
// 'joined_at' => \DateTime
// 'roles' => array('super', 'admin', 'user')

It's really that easy!

Casting

Below is a list of casting types available in the library

You can also pass in anything that can be called by call_user_func as the second argument in the propery map (see roles in the example) and the data can be casted that way. In our example it is turning a string into an array, exploding on the commas.

Property Access

So how do I get at the data?

Well each of the following lines will work.

$id = $user['id']; // Array Access
$id = $user->id; // Object Notation
$id = $user->get('id'); // Getter

get() has the added bonus of being able to add a default value as the second parameter. This is null if not explicitly set.

And setting?

You can set with Array Access, Object Notation or a Setter, just like when you are getting data out. All of the methods below will work.

$user['active'] = true;
$user->active = true;
$user->set('active', true);

Why?

Getting our data into native php has a lot of advantages, but the one I had in mind when develping this library is for API development. When we send our data it should be in native data types (i.e. booleans shouldn't come back as '0'). P.S. - you can call toJSON() on any NativeObject and get the json representation of it.
