Installation

Install via Composer:

composer require derafu/repository

Basic Usage

use Derafu\Repository\Repository;

// Load data from a PHP file or array.
$data = [
    'products' => [
        'prod-001' => [
            'name' => 'Laptop XPS',
            'category' => 'computers',
            'price' => 1299.99,
        ],
        // More products...
    ],
];

// Create a repository.
$repository = new Repository($data, idAttribute: 'id');

// Find all products.
$allProducts = $repository->findAll();

// Find products by criteria.
$computerProducts = $repository->findBy([
    'category' => 'computers'
]);

// Find a single product.
$laptop = $repository->findOneBy([
    'name' => 'Laptop XPS',
]);

Advanced Usage with Doctrine Criteria

use Doctrine\Common\Collections\Criteria;
use Doctrine\Common\Collections\Order;

// Advanced filtering with Doctrine Criteria.
$expensiveProducts = $repository->findByCriteria(
    Criteria::create()
        ->where(Criteria::expr()->gt('price', 1000))
        ->orderBy(['price' => Order::Descending])
);

Supported Data Sources

• PHP Arrays.
• PHP Files returning arrays.
• JSON Files.
• YAML Files.

Performance Considerations

• Optimized for small to medium-sized datasets.
• In-memory data management.
• Recommended for configuration, lookup tables, and static data.
