//set cache expiry time to 1 hour $cache_expiry = 3600; //set cache key and value $key = 'my_data'; $value = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'; //save data to cache apcu_store($key, $value, $cache_expiry); //retrieve data from cache $data = apcu_fetch($key);
//set cache expiry time to 30 minutes $cache_expiry = 1800; //set cache key and value $key = 'users_data'; $value = ['John', 'Jane', 'James']; //save data to cache $redis->set($key, json_encode($value)); $redis->expire($key, $cache_expiry); //retrieve data from cache $data = json_decode($redis->get($key));In this code example, we have used the `Redis` package library to set a cache expiry time of 30 minutes. The data is saved to cache using the `set()` function and encoded using `json_encode()`. The expiry time is then set using the `expire()` function. We can then retrieve the data from cache using the `get()` function and decoded using `json_decode()`.
