TreeWalker

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

Total Downloads License

  • 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

Version

0.9

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"}
