difference between 2 json in php

With TreeWalker you can do to get the difference between two objects in php:
https://github.com/lukascivil/TreeWalker
live example: http://treewalker.lukascivil.com.br/

<?php
include 'pathto/TreeWalker.php';

$treewalker = new TreeWalker(array(
"debug"=>true, //true => return the execution time, false => not
"returntype"=>"jsonstring") //Returntype = ["obj","jsonstring","array"]
);

Method:

//getdiff() - this method will return the diference between struct1 and struct2

$struct1 = array("casa"=>1, "b"=>"5", "cafeina"=>array("ss"=>"ddd"), "oi"=>5);
$struct2 = array("casa"=>2, "cafeina"=>array("ss"=>"dddd"), "oi2"=>5);

$treewalker->getdiff($struct1, $struct2, false) // false -> with slashs

Output:
{
 new: {
 b: "5",
 oi: 5
 },
 removed: {
 oi2: 5
 },
 edited: {
 casa: {
 oldvalue: 2,
 newvalue: 1
 },
 cafeina/ss: {
 oldvalue: "dddd",
 newvalue: "ddd"
 }
 },

}
