How do you implement file caching in Phalcon?

To implement file caching in Phalcon with minimal and necessary steps, follow this process:

Step 1: Set Up Cache Service

Define the cache service in your DI with file storage.

Example

<?php
use Phalcon\Cache;
use Phalcon\Storage\Adapter\Stream;
use Phalcon\Storage\SerializerFactory;

$di->setShared('cache', function() {
    $serializerFactory = new SerializerFactory();
    $options = ['storageDir' => __DIR__ . '/../storage/cache/']; // Cache directory

    $adapter = new Stream($serializerFactory, $options);
    return new Cache($adapter);
});
?>

Step 2: Use the Cache

Store and retrieve data from the cache.

Example

<?php
$cache = $this->di->get('cache');
$key = 'my-cache-key';

$data = $cache->get($key);
if ($data === null) {
    $data = 'New data to cache';
    $cache->set($key, $data);
}

echo $data;
?>
