[](#installation)

```

```

Usage
-----

[](#usage)

### Basic

[](#basic)

```
use PHPdot\Cache\Store;
use PHPdot\Cache\Driver\RedisDriver;

$cache = new Store(new RedisDriver($redis, prefix: 'app:'));

$cache->set('user:1', $userData, 3600);
$user = $cache->get('user:1');
$cache->delete('user:1');
$cache->has('user:1'); // false
```

### Remember pattern

[](#remember-pattern)

```
$user = $cache->remember('user:1', 3600, function () use ($db) {
    return $db->table('users')->find(1);
});
// First call: queries DB, caches result
// Subsequent calls: returns from cache

$config = $cache->rememberForever('app:config', fn() => loadConfig());
```

### Swap backends

[](#swap-backends)

```
$cache = new Store(new RedisDriver($redis, prefix: 'app:'));
$cache = new Store(new FileDriver('/var/cache/app'));
$cache = new Store(new ArrayDriver());
$cache = new Store(new ApcuDriver(prefix: 'app:'));
$cache = new Store(new NullDriver());
// Same API, different backend
```

### Batch operations

[](#batch-operations)

```
$cache->setMultiple([
    'user:1' => $user1,
    'user:2' => $user2,
], ttl: 3600);

$users = $cache->getMultiple(['user:1', 'user:2', 'user:3'], default: null);
$cache->deleteMultiple(['user:1', 'user:2']);
```

### LRU eviction (ArrayDriver)

[](#lru-eviction-arraydriver)

```
$cache = new Store(new ArrayDriver(maxItems: 1000));
// Evicts least recently used entry when full
```

### Custom driver

[](#custom-driver)

```
use PHPdot\Cache\DriverInterface;

final class MongoDriver implements DriverInterface
{
    // Implement 8 methods: get, set, delete, clear, has,
    // getMultiple, setMultiple, deleteMultiple
}

$cache = new Store(new MongoDriver($collection));
```

-----------------

[](#psr-16-compliance)

Store implements `Psr\SimpleCache\CacheInterface`:

- Key validation: rejects `{}()/\@:` characters and empty strings
- TTL normalization: accepts `int`, `DateInterval`, or `null`
- Negative TTL treated as expired
- Throws `PHPdot\Cache\Exception\InvalidArgumentException` for invalid keys

Notes
-----

[](#notes)

**`remember()` and null values:** PSR-16 cannot distinguish between "key not found" and "key stores null". If a `remember()` callback returns `null`, the callback will run on every call. Use `false` or a sentinel value instead of `null` for cacheable "empty" results.

      Loading Testing
-------

[](#testing)

The package is standalone-testable:

```
composer install
composer test        # PHPUnit (driver tests skip when ext-redis/ext-apcu are absent)
composer analyse     # PHPStan, level max + strict rules
composer cs-check    # PHP-CS-Fixer
composer check       # All three
```
