// Start APCu cache apcu_add('my_key', 'my_value'); // Retrieve data from cache $data = apcu_fetch('my_key'); // Display data echo $data;
// Start Memcached cache $memcache = new Memcached(); $memcache->addServer('localhost', 11211); // Retrieve data from cache $data = $memcache->get('my_key'); // Display data echo $data;
// Start Redis cache $redis = new Redis(); $redis->connect('localhost', 6379); // Retrieve data from cache $data = $redis->get('my_key'); // Display data echo $data;In this example, we start the Redis cache and connect to a server. Then, we retrieve the data by specifying the key and assign it to a variable. Finally, we display the data. In conclusion, the package library used depends on the specific caching requirements and preferences of the user or project.
