README

A pluggable and namespace-aware storage abstraction for temporarily persisting key-value data during scoped user interactions. This strategy supports session-based (cookie and token) and Redis-based implementations, and is designed to decouple application logic from underlying storage mechanisms.

Ideal for tracking transient states — such as validation progress, multistep workflows, or temporary metadata — using a consistent and replaceable strategy.

Features

• 🍪 Cookie-based PHP session
• 🆔 Token-based PHP session (stateless API support)
• 🚀 Redis storage for shared, scalable scenarios
• 🔌 PSR-style interface for easy integration and extension
• ✅ Unified interface with put, get, exists, remove, clear, etc.

Installation

composer require hizpark/scoped-storage-strategy

Usage

1. SessionStorageStrategy with Cookie

use Hizpark\ScopedStorageStrategy\SessionStorageStrategy;
use Hizpark\ScopedStorageStrategy\SessionInitializerWithCookie;

$initializer = new SessionInitializerWithCookie();
$strategy = new SessionStorageStrategy('scope-123', $initializer);

$strategy->put('demo-file-123', '/path/to/demo-file-123');
$value = $strategy->get('demo-file-123');

2. SessionStorageStrategy with Token (for stateless APIs)

use Hizpark\ScopedStorageStrategy\SessionStorageStrategy;
use Hizpark\ScopedStorageStrategy\SessionInitializerWithToken;

$token = $_GET['token'] ?? ''; // or from Authorization header
$initializer = new SessionInitializerWithToken($token);
$strategy = new SessionStorageStrategy('scope-456', $initializer);

$strategy->put('demo-file-456', '/path/to/demo-file-456');
$value = $strategy->get('demo-file-456');

3. RedisStorageStrategy

use Hizpark\ScopedStorageStrategy\RedisStorageStrategy;

$redis = new \Redis();
$redis->connect('127.0.0.1', 6379);

$strategy = new RedisStorageStrategy('scope-789', $redis);

$strategy->put('demo-file-789', '/path/to/demo-file-789');
$value = $strategy->get('demo-file-789');

Interface

All strategies implement the following interface:

namespace Hizpark\ScopedStorageStrategy;

interface ScopedStorageStrategyInterface
{
    public function put(string $key, string $value): void;
    public function get(string $key): ?string;
    public function exists(string $key): bool;
    public function remove(string $key): void;
    public function all(): ?array;
    public function empty(): bool;
    public function clear(): void;
}

And session-based strategies require a session initializer:

namespace Hizpark\ScopedStorageStrategy;

interface SessionInitializerInterface
{
    public function initialize(): void;
}
