TreeWalker

TreeWalker is a simple and small Library that will help you to work faster with manipulation of structures in PHP

• getdiff() - Get json difference
• replaceValues() - Edit json value (Recursively)
• walker() - Edit json (Recursively)
• structMerge() - Joins two structures
• createDynamicallyObjects() - Create nested structure by Dynamic keys
• getDynamicallyValue() - Dynamically get a structure property
• setDynamicallyValue() - Dynamically access a structure property to set a value

structure = [“jsonstring”, “object”, “array”]

EXAMPLE - master

Prerequisites

• PHP >= 5.5

Installation

Using composer

Put the require statement for TreeWalker in your composer.json and install:

{
  "require": {
    "lukascivil/treewalker": "dev-master"
  }
}

composer require lukascivil/treewalker dev-master

Manually

include the TreeWalker.php

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

Examples

Init:

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

Methods:

    //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"
            }
        },
        time: 0
    }

    //walker() - Walk recursively through the structure
    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");
    $treewalker->walker($struct, function(&$struct, $key, &$value) {
        //Removing element
        if ($key == "ff") {
            unset($struct[$key]);
        }
        //changing element
        if ($key == "ff1") {
            $value = array("son" => "tiago");
        }
    })
    Output:
    {"casa":2,"cafeina":{"ss":{"ff1":{"son":"tiago"}}},"oi2":5,"1":"","ss":"dddddf","time":"0 miliseconds"}

    //structMerge() - Merge Structures
    $struct1 = array("casa"=>1, "b"=>"5", "cafeina"=>array("ss1"=>"1", "ss2"=>"2"), "oi"=>5, "1" => "255");
    $struct2 = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");
    $treewalker->structMerge($struct2, $struct1, true); //true -> No slashs
    Output:
    {"casa":2,"b":"5","cafeina":{"ss1":"1","ss2":"2","ss":{"ff":21,"ff1":22}},"oi":5,"0":"255","oi2":5,"1":"","ss":"dddddf","time":"0 miliseconds"}

    //createDynamicallyObjects() - this method will create nested objects with with dynamic keys
    $struct = array("casa"=>1, "b"=>"5", "cafeina"=>array("ss"=>"ddd"), "oi"=>5, "1" => "255");
    //P.s
    $treewalker->createDynamicallyObjects($struct, array(1,2,5,9,10,11));
    Output:
     {
       "casa": 1,
       "b": "5",
       "cafeina": {
          "ss": "ddd"
       },
       "oi": 5,
       "1": {
          "2": {
            "5": {
              "9": {
                "10": {
                  "11": {}
                }
              }
            }
          }
        }
      }

    //getDynamicallyValue()
    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");
    Static access:
    $struct["cafeina"]["ss"];
    Dynamic access:
    $treewalker->getDynamicallyValue($struct, array("cafeina","ss"));
    Output:
    {"ff":21,"ff1":22}

    //setDynamicallyValue()
    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");
    Static access:
    $struct["cafeina"]["ss"] = "newvalue";
    Dynamic access:
    $treewalker->setDynamicallyValue($struct, array("cafeina","ss"), "newvalue");
    Output:
    {"casa":2,"cafeina":{"ss":"newvalue"},"oi2":5,"1":"","ss":"dddddf"}

Test

composer install
composer test

Additional context

If you need the JS version to also compare objects, you can use this (JsonDifference) lib which will have the same result on the client side.
