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.
