Create PHP Object from JSON Content

#php #json #popo #jsonparser

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... }

Now you want to convert this JSON to POPO with relations. The ABGEO07/json-to-popo package gives you this ability. Install it using Composer:
composer require abgeo/json-to-popo

Now 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" // } // } //}

Hi, I started work on something similar but uses PHP 8 attributes, take a look github.com/mrbenosborne/json-unmar....

<?php use JSON\Attributes\JSON; use JSON\Unmarshal; include '../vendor/autoload.php'; include 'FlightRoute.php'; /** * Class Flight */ class Flight { #[JSON(field: 'airline')] public string $airlineName; #[JSON(field: 'aircraft.type')] public string $aircraftType; #[JSON(field: 'route', type: FlightRoute::class)] public array $route; } // Create a new flight class $flight = new Flight(); // Load our JSON data from file $jsonData = json_decode(file_get_contents('flight.json'), true); // Unmarshal JSON Unmarshal::decode($flight, $jsonData);
