Redis Cache

This project is build upon my first redis open PHP project Redis Adapter. Thanks to it you can use either Predis client or native PHP Redis client in a transparent way.

If PHP redis is installed

$ apt-get install php8.x-redis

These implementations will use it or fallback on Predis client otherwise.

Install

composer require llegaz/redis-cache
composer install

PSR-6

PSR-6 implementation is my implementation of Caching Interface from the PHP FIG www.php-fig.org/psr/psr-6 It is far from perfect and as of now (first versions of this implementation) you should be aware that pool expiration are available but by pool's fields expiration are not really ! I will try to test and implement a pool key expiration for Valkey.io in a near future but my first draft is: if you expire a pool key it will expire your entire pool SO BE EXTRA CAUTIOUS WITH THAT !

Caution

if you expire a pool key it will expire your entire pool SO BE EXTRA CAUTIOUS WITH THAT !

Basic usage

$cache = new LLegaz\Cache\RedisEnhancedCache();
$cart = new \LLegaz\Cache\Pool\CacheEntryPool($cache);
$user = new \LLegaz\Cache\Pool\CacheEntryPool($cache, 'lolo');

$id = $user->getItem('id');
if ($id->isHit()) {
    $item = $cart->getItem('banana:' . $id->get());
    $item->set('mixed value');
    $cart->save($item);
} else {
    $id->set('the lolo id');
    $user->save($id);
}

Batch

foreach ($cart as $item) {
    $cart->saveDeferred($item); // items are commited on pool object destruct
}

PSR-16

My Simple Cache implementation PHP FIG PSR-16 www.php-fig.org/psr/psr-16

    $cache = new LLegaz\Cache\RedisCache();
    $cache->selectDatabase(3); // switch database
    $cache->set('key', 'mixed value, could be an object or an array');
    $cache->get('key'));


    $cache->setMultiple(['key1' => [], 'key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4'], 90); // 1m30s expiration on each key
    if ($cache->has('key1') && $cache->has('key4')) {
        $array = $cache->getMultiple(['key1', 'key1', 'key4']));
        var_dump(count($array)); // int(2)
        var_dump($array); // array(2) { ["key1"]=> string(6) "value1" ["key4"]=> string(6) "value4" }
    }

Configuration

$cache = new LLegaz\Cache\RedisCache();

is equivalent to

$cache = new LLegaz\Cache\RedisCache('127.0.0.1');

or

$cache = new LLegaz\Cache\RedisCache('localhost', 6379, null, 'tcp', 0, false); // the nulled field is the Redis password in clear text (here no pwd)

Persistent connection

$cache = new LLegaz\Cache\RedisCache('localhost', 6379, null, 'tcp', 0, true);

Contributing

You're welcome to propose things. I am open to criticism as long as it remains benevolent.

Stay tuned, by following me on github, for new features using predis and PHP Redis.
