Override of Symfony PSR6 cache RedisAdapter, retrieving expiration on an existing item.
This allows, for instance, to increment a value into the cache until it expires. The original Symfony cache implementation actually resets the expiration delay after each save().
Example use :
$redis = new Redis(); $redis->connect('127.0.0.1'); $cache = new \BenTools\Cache\Adapter\RedisTTLAwareAdapter($redis); $key = 'my.example'; # Assume my.example does not exist var_dump($cache->hasItem($key)); // false $item = $cache->getItem($key); $item->set(1); $item->expiresAfter(5); // expires in 5 seconds $cache->save($item); sleep(2); # After 2 seconds, my.example == 1 var_dump($cache->hasItem($key)); // true $item = $cache->getItem($key); $value = $item->get(); // 1 var_dump($value); // 1 $item->set($value + 1); $cache->save($item); sleep(2); # After 4 seconds, my.example == 2 var_dump($cache->hasItem($key)); // true $item = $cache->getItem($key); $value = $item->get(); var_dump($value); // 2 $item->set($value + 1); $cache->save($item); sleep(2); # After 6 seconds, my.example does not exist anymore var_dump($cache->hasItem($key)); // false $item = $cache->getItem($key); $value = $item->get(); var_dump($value); // null
