First In – First Out (FIFO)
<?php $cache = new \Ropi\InMemoryCache\FifoInMemoryCache(defaultTtl: null, maxSize: 3); $cache->set('a', 10); $cache->set('b', 20); $cache->set('c', 30); var_dump($cache->get('b')); // Prints 20 var_dump($cache->count()); // Prints 3 $cache->set('d', 40); var_dump($cache->count()); // Still prints 3, because cache size is limited to 3 and thus first cache entry was deleted var_dump($cache->get('a')); // Prints NULL, because 'a' was the first cache entry var_dump($cache->get('d')); // Prints 40
Fixed sized
<?php $cache = new \Ropi\InMemoryCache\FixedSizedInMemoryCache(defaultTtl: null, maxSize: 3); $cache->set('a', 10); $cache->set('b', 20); $cache->set('c', 30); var_dump($cache->get('b')); // Prints 20 var_dump($cache->count()); // Prints 3 $cache->set('d', 40); // Throws OverflowException, because cache size is limited to 3
Time-to-live (TTL)
<?php $cache = new \Ropi\InMemoryCache\InMemoryCache(defaultTtl: 2); $cache->set('a', 10); var_dump($cache->get('a')); // Prints 10 sleep(3); var_dump($cache->get('a')); // Prints NULL, because TTL expired
