json-to-popo

Fill Plain Old PHP Object with JSON content.

Installation

You can install this library with Composer:

• composer require abgeo/json-to-popo

Usage

Include composer autoloader in your main file (Ex.: index.php)

• require __DIR__.'/../vendor/autoload.php';

Consider that you have example.json with the following content:

{
  "firstName": "Temuri",
  "lastName": "Takalandze",
  "active": true,
  "position": {
    "title": "Developer",
    "department": {
      "title": "IT"
    }
  }
}

and several POPO classes to represent this JSON data:

Department.php

<?php

class Department
{
    /**
     * @var string
     */
    private $title;

    // Getters and Setters here...
}

Position.php

<?php

class Position
{
    /**
     * @var string
     */
    private $title;

    /**
     * @var \ABGEO\POPO\Example\Department
     */
    private $department;

    // Getters and Setters here...
}

Person.php

<?php

class Person
{
    /**
     * @var string
     */
    private $firstName;

    /**
     * @var string
     */
    private $lastName;

    /**
     * @var bool
     */
    private $active;

    /**
     * @var \ABGEO\POPO\Example\Position
     */
    private $position;

    // Getters and Setters here...
}

Note: All POPO properties must have full qualified @var annotation with the correct data type.

Now you want to convert this JSON to POPO with relations. This package gives you this ability.

Let's create new ABGEO\POPO\Composer object and read example.json content:

$composer = new Composer();
$jsonContent = file_get_contents(__DIR__ . '/example.json');

Time for magic! Call composeObject() with the contents of JSON and the main class, and this will give you POPO:

$resultObject = $composer->composeObject($jsonContent, Person::class);

Print $resultObject:

var_dump($resultObject);

//class ABGEO\POPO\Example\Person#2 (4) {
//  private $firstName =>
//  string(6) "Temuri"
//  private $lastName =>
//  string(10) "Takalandze"
//  private $active =>
//  bool(true)
//  private $position =>
//  class ABGEO\POPO\Example\Position#4 (2) {
//    private $title =>
//    string(9) "Developer"
//    private $department =>
//    class ABGEO\POPO\Example\Department#7 (1) {
//      private $title =>
//      string(2) "IT"
//    }
//  }
//}
