README

The MagicObject class is an excellent choice for manipulating structured data. For example, configuration data represented by JSON, XML, YML, etc.

The MagicObject can also be used for representing a database entry and the class extending it is often called Model.

$obj->setSomething(123);
$obj->getSomething(); // 123

The Magic Getter and Setter can make your code extremely simple and straightforward. For detailed usage, see the full example section.

Requirements

• php >= 5.3

Installation

composer require wubinworks/magic-object

Usage

Data path naming

The MagicObject stores nested array data and those nested array keys can be represented by "path".

The key's separator is /. The best practice to name a path is to use lowercase letters, digits and underscores for keys only and the keys should begin with a lowercase letter.

For instance, this/is/a/path. The keys are this, is, a and path.

/** @var \Wubinworks\MagicObject\Data\MagicObject $obj */
$obj->setData('this/is/a/path', 'some value');
$obj->getData('this/is/a/path'); // some value

Path and method name conversion

Here is the Magic. The path can be converted to Getter and Setter method name.

/** @var \Wubinworks\MagicObject\Data\MagicObject $obj */
$obj->getData(<snake_case path>)
$obj->get<PascalCase partial method name>()

$obj->setData(<snake_case path>, $value)
$obj->set<PascalCase partial method name>($value)

$obj->hasData(<snake_case path>)
$obj->has<PascalCase partial method name>()

$obj->unsData(<snake_case path>)
$obj->uns<PascalCase partial method name>()

The above example demonstrates how snake_case path is converted to PascalCase partial method name, and vice versa.

Note the key's separator / is converted to _, and vice versa.

For instance, customer/reward_points/expired <==> Customer_RewardPoints_Expired.

You may still be confused, so see the full example below.

Full example

$data = json_decode('{
    "customer": {
        "name": "John Smith",
        "gender": null,
        "age": 25,
        "reward_points": {
            "used": 1000,
            "expired": 2000
        }
    },
    "order_number": 111111111
}', true);
/*
$data = [
    'customer' => [
        'name' => 'John Smith',
        'gender' => null,
        'age' => 25,
        'reward_points' => [
            'used' => 1000,
            'expired' => 2000
        ];
    ],
    'order_number' => 11111111
];
*/

// Feed the object with data. Array with numeric keys are *NOT* supported.
$obj = new \Wubinworks\MagicObject\Data\MagicObject($data);

// Getter

$obj->getData('order_number'); // 11111111
$obj->getOrderNumber(); // 11111111

$obj->getData('customer/reward_points/used'); // 1000
$obj->getCustomer_RewardPoints_Used(); // 1000

// If the path does not exist, null will be returned and no exception will be thrown.
$obj->getData('customer/nonexist_key'); // null
$obj->getCustomer_NonexistKey(); // null

// Get all data
$obj->getData(/** No path parameter */); // $data

// Setter

$obj->setData('order_number', 22222222);
$obj->getData('order_number'); // 22222222
$obj->setOrderNumber(33333333);
$obj->getData('order_number'); // 33333333

$obj->setData('customer/reward_points/used', 7777);
$obj->getData('customer/reward_points/used'); // 7777
$obj->setCustomer_RewardPoints_Used(8888);
$obj->getData('customer/reward_points/used'); // 8888
$obj->setData('customer/new_key', 9999);
$obj->getData('customer/new_key'); // 9999

// Replace all data
// Actually, it is Setter. Note the path parameter of setData is null.

$arr = ['a' => 1, 'b' => 2];
$obj->setData(null, $arr);
$obj->getData(); // $arr

// Has path

$obj->setData(null, $data);
$obj->hasData('customer/gender'); // true
$obj->hasCustomer_Gender(); // true
$obj->hasData('customer/nonexist_key'); // false

// Unset path ("uns" means "unset")
// Always succeeds, even if the path does not exist.
// Note the path parameter of unsData cannot be null and must be string

$obj->unsData('customer/gender');
$obj->hasData('customer/gender'); // false
$obj->unsCustomer_Age();
$obj->hasData('customer/age'); // false

$obj->unsData('customer/nonexist_key');
$obj->unsCustomer_NonexistKey();
