How do you use Phalcon’s PhalconCacheFrontendData class?

To use Phalcon’s Phalcon\Cache\Frontend\Data class, follow these  steps:

1. Initialize the Frontend Data Cache

Create an instance of the Data frontend cache with a lifetime (expiration time):

Example

<?php
use Phalcon\Cache\Frontend\Data as FrontendData;

$frontend = new FrontendData([
    'lifetime' => 3600  // Cache for 1 hour
]);
?>

2. Set Up the Backend

Choose a backend cache (e.g., File, Redis) and configure it:

Example

<?php
use Phalcon\Cache\Backend\File as BackendFile;

$cache = new BackendFile($frontend, [
    'cacheDir' => '../app/cache/'  // Directory to store cache files
]);
?>

3. Store Data in Cache

To save data in the cache:

Example

<?php
$cache->save('cache_key', 'some_cached_data');
?>

4. Retrieve Cached Data

To retrieve cached data:

Example

<?php
$data = $cache->get('cache_key');
?>

5. Check if Data Exists in Cache

To check if the cache contains a specific key:

Example

<?php
if ($cache->exists('cache_key')) {
    echo "Data exists in cache";
}
?>

6. Delete Cached Data

To remove cached data:

Example

<?php
$cache->delete('cache_key');
?>
