This is a wrapper around graviton/rql-parser that combines that parser with a small layer of Doctrine DBAL integration.

Installation

Install it using composer.

composer require chronext/rql2dbal

Usage

<?php declare(strict_types=1);

require 'vendor/autoload.php';

use Chronext\Rql2Dbal\Rql2Builder;
use Doctrine\DBAL\Connection;
use Doctrine\DBAL\Driver\Statement;
