#Key Value Store
Key Value Store is a library which abstracts the most used key value stores, like Redis or Memcached.
Description
This library provides an abstraction layer for key value stores. It is literally an abstraction because it contains only contracts and fundemantal implementations. So you need to install a store specific implementation a.k.a. an adapter.
Adapters
These are separate repositories!
Planned adapters
- Apc
- Couchbase
- ?
Installation
This is an abstract package not a store specific implementation.
Please visit the links in the Adapters section.
Usage
with Redis (through predis/predis)
<?php use AdammBalogh\KeyValueStore\KeyValueStore; use AdammBalogh\KeyValueStore\Adapter\RedisAdapter as Adapter; use Predis\Client as RedisClient; $redisClient = new RedisClient(); $adapter = new Adapter($redisClient); $kvs = new KeyValueStore($adapter); $kvs->set('sample_key', 'Sample value'); $kvs->get('sample_key'); $kvs->delete('sample_key');
To see other specific examples please visit the links in the Adapters section.
API
You can call all of the API methods on a instance of KeyValueStore
.
Key
/** * Removes a key. * * @param string $key * * @return bool True if the deletion was successful, false if the deletion was unsuccessful. * * @throws \InvalidArgumentException * @throws InternalException */ public function delete($key); /** * Sets a key's time to live in seconds. * * @param string $key * @param int $seconds * * @return bool True if the timeout was set, false if the timeout could not be set. * * @throws \InvalidArgumentException * @throws InternalException */ public function expire($key, $seconds); /** * Returns the remaining time to live of a key that has a timeout. * * @param string $key * * @return int Ttl in seconds. * * @throws \InvalidArgumentException * @throws KeyNotFoundException * @throws InternalException */ public function getTtl($key); /** * Determines if a key exists. * * @param string $key * * @return bool True if the key does exist, false if the key does not exist. * * @throws \InvalidArgumentException * @throws InternalException */ public function has($key); /** * Removes the existing timeout on key, turning the key from volatile (a key with an expire set) * to persistent (a key that will never expire as no timeout is associated). * * @param string $key * * @return bool True if the persist was success, false if the persis was unsuccessful. * * @throws \InvalidArgumentException * @throws InternalException */ public function persist($key);
Value
/** * Gets the value of a key. * * @param string $key * * @return mixed The value of the key. * * @throws \InvalidArgumentException * @throws KeyNotFoundException * @throws InternalException */ public function get($key); /** * Sets the value of a key. * * @param string $key * @param mixed $value Can be any of serializable data type. * * @return bool True if the set was successful, false if it was unsuccessful. * * @throws \InvalidArgumentException * @throws InternalException */ public function set($key, $value);
Server
/** * Removes all keys. * * @return void * * @throws \AdammBalogh\KeyValueStore\Exception\InternalException */ public function flush();
