Simple Cache
============

[](#simple-cache)

A simple and transparent caching library for PHP with multiple driver support.

Features
--------

[](#features)

- Lightweight and easy-to-use API
- Multiple drivers: File, Memcached, Redis, Database, Mock
- Built-in support for the "remember" pattern
- Mock driver for testing

Installation
------------

[](#installation)

```
composer require sanovskiy/simple-cache
```

Requirements
------------

[](#requirements)

- PHP 8.0 or higher
- For File driver: No additional requirements
- For Memcached driver: `ext-memcached` (version >= 3.0 recommended)
- For Redis driver: `ext-redis` (version >= 5.0 recommended)
- For Database driver: `ext-pdo` with appropriate database driver (e.g., `ext-pdo-mysql`)
- For Mock driver: No additional requirements

Configuration
-------------

[](#configuration)

### Files

[](#files)

```
use Sanovskiy\SimpleCache\Cache;
use Sanovskiy\SimpleCache\Drivers\FileCacheDriver;

$cache = new Cache([
    'driver' => FileCacheDriver::class,
    'config' => [
        'directory' => '/var/cache/',
        'file_extension' => '.cache'
    ]
]);
```

### Memcached

[](#memcached)

```
use Sanovskiy\SimpleCache\Cache;
use Sanovskiy\SimpleCache\Drivers\MemcachedCacheDriver;
$cache = new Cache([
    'driver' => MemcachedCacheDriver::class,
    'config' => [
        'servers' => [['127.0.0.1', 11211]],
        'prefix' => 'app_'
    ]
]);
```

### Redis

[](#redis)

```
use Sanovskiy\SimpleCache\Cache;
use Sanovskiy\SimpleCache\Drivers\RedisCacheDriver;
$cache = new Cache([
    'driver' => RedisCacheDriver::class,
    'config' => [
        'host' => '127.0.0.1',
        'port' => 6379,
        'prefix' => 'app_',
        'database' => 0
    ]
]);
```

### SQL database

[](#sql-database)

```
use Sanovskiy\SimpleCache\Cache;
use Sanovskiy\SimpleCache\Drivers\DatabaseCacheDriver;
$cache = new Cache([
    'driver' => DatabaseCacheDriver::class,
    'config' => [
        'dsn' => 'mysql:host=localhost;dbname=cache_db',
        'username' => 'user',
        'password' => 'pass',
        'table' => 'cache'
    ]
]);
```

> Note: The DatabaseCacheDriver automatically creates cache table with columns key, value, expires\_at, created\_at, and updated\_at (with an index on expires\_at) if it doesn't exist. Ensure the database user has CREATE TABLE and INDEX permissions.

### Mock cache for testing

[](#mock-cache-for-testing)

```
$cache = new Cache([
    'driver' => \Sanovskiy\SimpleCache\Drivers\MockCacheDriver::class,
    'config' => [
        'emulate_failures' => false, // If true will emulate failure at every operation
        'log_operations' => true
    ]
]);
```

### Usage

[](#usage)

#### Basic usage

[](#basic-usage)

```
$cache->set('key', 'value', 3600);
$value = $cache->get('key', 'default');
$has = $cache->has('key');
$cache->delete('key');
$cache->clear();
```

#### Using the "remember" pattern:

[](#using-the-remember-pattern)

```
$data = $cache->remember('expensive_data', function() {
    return expensiveOperation();
}, 1800);
```

Drivers
-------

[](#drivers)

Simple Cache supports the following drivers:

- **File**: Stores cache in files on the filesystem.
    - Config: `directory` (path to cache directory), `file_extension` (e.g., `.cache`)
- **Memcached**: Uses a Memcached server for distributed caching.
    - Config: `servers` (array of \[host, port\]), `prefix` (key prefix)
- **Redis**: Uses a Redis server for high-performance caching.
    - Config: `host`, `port`, `prefix`, `database`, `password`, `timeout`
- **Database**: Stores cache in an SQL database (e.g., MySQL, PostgreSQL).
    - Config: `dsn`, `username`, `password`, `table`
- **Mock**: In-memory driver for testing, does not persist data.
    - Config: `emulate_failures` (bool), `log_operations` (bool)

Testing
-------

[](#testing)

To run tests locally, ensure Memcached, Redis, and MySQL are running and PHP extensions (`ext-memcached`, `ext-redis`, `ext-pdo_mysql`) are installed. Then run:

```
composer install
./vendor/bin/phpunit tests/
```

To run the tests using Docker Compose:

```
docker-compose up --build
```

To generate a code coverage report:

```
docker-compose run php sh -c "composer install && ./vendor/bin/phpunit tests/ --coverage-html coverage"
```

Why Simple Cache?
-----------------

[](#why-simple-cache)

Simple Cache is designed to be a lightweight, transparent, and easy-to-use caching library for PHP. Unlike other caching libraries that come with complex configurations or heavy dependencies, Simple Cache focuses on:

- **Simplicity**: Intuitive API with minimal setup.
- **Flexibility**: Supports multiple drivers (File, Memcached, Redis, Database, Mock) out of the box.
- **Testability**: Includes a Mock driver for easy unit testing.
- **Lightweight**: Minimal dependencies for better performance in small to medium projects.

Roadmap
-------

[](#roadmap)

- Add support for PSR-6 (Caching Interface) in future versions
- Add support for additional drivers (e.g., APCu)
