JsonFileManager PHP Library

JsonFileManager is a lightweight PHP class for simple, robust manipulation of JSON files—read, write, update, search, and remove using dot notation.

Installation

Install via Composer:

composer require jess/jsonkit-php

Usage

Quick Start

use Jess\JsonkitPhp\JsonFileManager;

// Initialize from a file path
$handler = new JsonFileManager('data.json', true);

// Get all data
$data = $handler->all();

// Get a value (dot notation supported)
$name = $handler->get('user.name');

// Set a value
$handler->set('user.age', 30);

// Append a value to an array
$handler->appendArray('tags', 'php');

// Remove a value from an array
$handler->removeArrayValue('tags', 'php');

// Remove where condition
$handler->removeWhere('users', function($user) {
    return $user['active'] === false;
});



// Save changes
$handler->save();

// You can load array data and save it to a json file.
$arr = [
     'numbers' => ['1', '2', '3']
];
$data = $handler->load($arr)->save(__DIR__ . 'test.json');
