README

A PHP implementation of the JSONata query and transformation language. This library allows you to query, transform, and manipulate JSON data structures in your PHP applications using the powerful and intuitive JSONata syntax.

What is JSONata?

JSONata is a lightweight query and transformation language for JSON data. Inspired by XPath 3.1, it provides a powerful way to extract and reshape data from any JSON document. It's perfect for complex data manipulation, templating, and data mapping tasks.

Features

• Support for basic JSONata queries.
• Map operator for simple transformations.
• Conditional logic.
• Simple, intuitive API.
• No external dependencies.
• Robust error handling.

Installation

You can install the package via Composer:

composer require monster-anshu/jsonata-php

Usage

Using the library is straightforward. You create an instance of the Jsonata class, provide your JSONata expression, and then evaluate it against your data.

Basic Example

Here's a simple example of how to extract the name of each product from a JSON object.

<?php

require __DIR__ . 'vendor/autoload.php';

use Monster\JsonataPhp\Jsonata;

const expression = '
Account.Order.Product[Price > 50].{ "id": ProductID, "total": Price * Quantity }
';

const input = [
    "Account" => [
        "Order" => [
            "Product" => [
                ["ProductID" => "A1", "Price" => 100, "Quantity" => 2],
                ["ProductID" => "A2", "Price" => 30, "Quantity" => 1],
            ],
        ],
    ],
];


$jsonata = new Jsonata(expression);
$result = $jsonata->evaluate(input);
print_r($result);

Expected Output:

Array
(
    [id] => A1
    [total] => 200
)
