README

Creates object of native classes from JSON string or object json-2-php-class is a library for converting json objects to native classes.

Requirements

• PHP 7.2 and above. (Should be checked!)

Installation

1. Using Composer

You can install the library via Composer. If you don't already have Composer installed, first install it from here.

After composer is installed, Then run the following command to install the json-2-php-class library:

composer require eden-tech-labs/json-2-php-class

2. Manually

Warning: You have to require the used classes or make an autoload function to do this.
If you're not using Composer, you can also clone eden-tech-labs/json-2-php-class repository into a directory in your project:

git clone https://github.com/eden-tech-labs/json-2-php-class

However, using Composer is recommended as you can easily keep the library up-to-date and deal with autoloading.

Usage

After you installed json-2-php-class library, in your classes you should implement the interface and use the trait and that satisfies the interface requirements. After that you should override the _mapping() method. You can check the implementation and documentation below. You can define your properties in the class or in the PHPDoc as in the example. After you define your properties rules you can export PHPDoc. Example below.(TODO: put link here)

Sample Class

use DateTime;
use EdenTechLabs\JSON2PHPClass\MadeFromDataContract;
use EdenTechLabs\JSON2PHPClass\MadeFromJson;
use EdenTechLabs\Common\Enum;

/**
 * Class MyApp\SampleClass
 * @property string applicationId
 * @property SampleKind kind
 * @property DateTime purchaseTime
 * @property object developerPayload
 * @property int quantity
 * @property bool acknowledged
 * @property SamplePayload samplePayload
 */
class SampleClass implements MadeFromDataContract
{
    use MadeFromJson;

    protected static function _mapping(): array
    {
        return [
            'applicationId' => 'string',
            'kind' => SampleKind::class,
            'purchaseTime' => 'milliseconds',
            'developerPayload' => 'json',
            'quantity' => 'int',
            'acknowledged' => 'bool',
            'samplePayload' => SamplePayload::class,
        ];
    }
}

/**
 * Class MyApp\SamplePayload
 * @property string stupidId
 * @property bool autoRenewing
 * @property \DateTime purchaseTime
 */
class SamplePayload implements MadeFromDataContract
{
    use MadeFromJson;

    protected static function _mapping() : array {
        return [
            'stupidId' => 'string',
            'autoRenewing' => 'bool',
            'purchaseTime' => 'seconds'
        ];
    }

}

class SampleKind extends Enum
{
    const KIND_ZERO = '0';
    const KIND_ONE = '1';
    const KIND_TWO = '2';
    const KIND_TREE = '3';
}

Sample Usage

$json = '
{
  "applicationId": "app-id-1",
  "kind": 2,
  "purchaseTime": "1584805754123",
  "developerPayload": "{\"foo\":\"bar\"}",
  "quantity": 34,
  "acknowledged": true,
  "samplePayload": {
    "stupidId": "foo-bar-45",
    "autoRenewing": false,
    "purchaseTime": 1584805754
  }
}
';

$myClass = SampleClass::make($json);
var_dump($myClass);

Output:

object(SampleClass)#1 (7) {
  ["applicationId"]=>
  string(8) "app-id-1"
  ["kind"]=>
  object(SampleKind)#3 (1) {
    ["value":protected]=>
    int(2)
  }
  ["purchaseTime"]=>
  object(DateTime)#4 (3) {
    ["date"]=>
    string(26) "2020-03-21 15:49:14.000000"
    ["timezone_type"]=>
    int(1)
    ["timezone"]=>
    string(6) "+00:00"
  }
  ["developerPayload"]=>
  object(stdClass)#5 (1) {
    ["foo"]=>
    string(3) "bar"
  }
  ["quantity"]=>
  int(34)
  ["acknowledged"]=>
  bool(true)
  ["samplePayload"]=>
  object(SamplePayload)#6 (3) {
    ["stupidId"]=>
    string(10) "foo-bar-45"
    ["autoRenewing"]=>
    bool(false)
    ["purchaseTime"]=>
    object(DateTime)#7 (3) {
      ["date"]=>
      string(26) "2020-03-21 15:49:14.000000"
      ["timezone_type"]=>
      int(1)
      ["timezone"]=>
      string(6) "+00:00"
    }
  }
}

As a property mapping you can define this types:

• int Integer
• string String
• float Any Number that has fraction part
• bool Boolean
• milliseconds PHP DateTime object generated from string or int containing timestamp in milliseconds
• seconds PHP DateTime object generated from string or int containing timestamp in seconds
• json Standard PHP object generated trough json_decode
• unknown The value is assigned to the property without any transformations.
• AnyClass::class
  • If implements MadeFromDataContract an object will be created using make function
  • Any other class will be created by __construct passing the value as first and only parameter.
• Closure To be defined.

PHPDoc

Example

echo SampleClass::generatePHPDoc();

Output

/**
 * Class SampleClass
 * @property string applicationId
 * @property \SampleKind kind
 * @property \DateTime purchaseTime
 * @property object developerPayload
 * @property int quantity
 * @property bool acknowledged
 * @property \SamplePayload samplePayload
