Horde HashTable
===============

[](#horde-hashtable)

Key/Value store abstraction with driver-specific capabilities for Redis native data structures, cross-process locking and transparent serialization of mixed PHP values.

Interfaces
----------

[](#interfaces)

InterfaceCapability`HashTable`get/set/delete/exists with mixed values and optional TTL`LockableHashTable`Cross-process lock/unlock (Redis, Memcache)`RedisHashTable`Atomic counters, hashes, lists, sets, TTL introspectionDrivers
-------

[](#drivers)

DriverImplementsBackend`Driver\Redis``RedisHashTable`ext-redis (preferred) or Predis ^3`Driver\Memcache``LockableHashTable``Horde\Memcache\MemcacheApi``Driver\Memory``HashTable`In-process array (testing/development)`Driver\NullDriver``HashTable`No-op (always misses)Installation
------------

[](#installation)

```
composer require horde/hashtable
```

For Redis (recommended):

```
# Preferred: C extension
pecl install redis

# Fallback: pure PHP
composer require predis/predis:^3
```

Usage
-----

[](#usage)

```
use Horde\HashTable\Driver\Redis;
use Redis as PhpRedis;

$client = new PhpRedis();
$client->connect('127.0.0.1', 6379);

$ht = new Redis(client: $client, prefix: 'myapp_');

// Basic key-value
$ht->set('user:1', ['name' => 'Alice'], ttl: 3600);
$data = $ht->get('user:1');  // returns array or null

// Locking
$ht->lock('user:1');
try {
    $ht->set('user:1', ['name' => 'Bob']);
} finally {
    $ht->unlock('user:1');
}

// Redis-native structures
$ht->increment('counter');
$ht->listPush('queue', $job);
$ht->hashSet('session:abc', 'last_access', time());
$ht->setAdd('tags:post:1', 'php', 'redis');
```

Horde Core Integration
----------------------

[](#horde-core-integration)

When used inside a Horde application, you can obtain instances via dependency injection:

```
use Horde\HashTable\HashTable;
use Horde\HashTable\LockableHashTable;
use Horde\HashTable\RedisHashTable;

// Any configured driver
$ht = $injector->get(HashTable::class);

// Only drivers with real cross-process locking
$ht = $injector->get(LockableHashTable::class);

// Full Redis power (counters, hashes, lists, sets)
$ht = $injector->get(RedisHashTable::class);
```

Configuration is read from `conf.php` under the `hashtable` key by `Horde\Core\Factory\HashTableFactory`.

Legacy API
----------

[](#legacy-api)

The PSR-0 classes under `lib/` (`Horde_HashTable_Base`, `Horde_HashTable_Predis`, etc.) remain available for backward compatibility. New code should use the PSR-4 interfaces in `src/`. See [doc/UPGRADING.md](doc/UPGRADING.md) for migration details.
