Implementation of JSON Patch (http://tools.ietf.org/html/rfc6902) in PHP, _(*2)

Installation

Require victuxbb/jsonpatch into your composer.json file:, _(*3)

``` json { "require": { "victuxbb/jsonpatch": "@stable" } }, _(*4)

or inside your root project directory

``` bash

$ composer require victuxbb/jsonpatch @stable

Documentation

With a target JSON like this: ``` php $targetJSON ='{"baz": "qux","foo": "bar"}';, _(*5)

and a variable with a JSON string operations:
``` php
$patchOperations = '[
     { "op": "replace", "path": "/baz", "value": "boo" }
   ]';

create a instance of Patcher and use the "patch" method to get the json result:, _(*6)

``` php $patcher = new Patcher(); $result = $patcher->patch($targetJSON,$patchOperations);, _(*7)

$result will contain:
``` json
{"baz":"boo","foo":"bar"}

A typical use case with FOSRestBundle and JMSSerializer: ``` php public function patchUserAction(Request $request,User $user) {
$json = $request->getContent(); $jps = $this->get('json_patch_service'); //symfony service that loads Patcher.php $serializer = $this->get("jms_serializer");, _(*8)

    $serializerGroup = array('view');

    $sc = SerializationContext::create();
    $sc->setGroups($serializerGroup);

    $jsonUser = $serializer->serialize($user,'json',$sc); //Generating the json target of object that we want to update
    $jsonUser = $jps->patch($jsonUser,$json); //json result with the changes applied of the json operations

    $dc = DeserializationContext::create();
    $dc->setAttribute('target',$user);

    //Restore the doctrine entity object with deserialization and targeting the object with DeserializationContext
    $serializer->deserialize($jsonUser,'Groupalia\BizApiBundle\Entity\User','json',$dc);

    $em = $this->getDoctrine()->getManager();
    $em->persist($user);
    $em->flush();

    $response = new Response();
    $response->setStatusCode(200);

    return $response;

}
