As of the V3 the bundle is absolutely not compatible with previous versions.
To ensure you the smoothest migration possible, please check the migration guide in the Resources/Docs directory.
One of the biggest change is the Phpfastcache's dependency which is not set to the v7 which it not backward compatible at all.
composer require phpfastcache/phpfastcache-bundle
# PhpFastCache configuration
phpfastcache:
twig_driver: "filecache" # This option must be a valid declared driver, in our example: "filecache"
twig_block_debug: false # This option will wrap CACHE/ENDCACHE blocks with block debug as HTML comment
drivers:
filecache:
type: Files
parameters:
path: "%kernel.cache_dir%/phpfastcache/"
- This step can be skipped using Symfony recipes.
Caching data in your controller:
public function indexAction(Request $request, Phpfastcache $phpfastcache)
{
$cache = $phpfastcache->get('filecache');
$item = $cache->getItem('myAppData');
if (!$item->isHit() || $item->get() === null) {
$item->set('Wy app has now superpowers !!')->expiresAfter(3600);//1 hour
$cache->save($item);
}
// replace this example code with whatever you need
return $this->render('default/index.html.twig', [
'myAppData' => $item->get(),
'base_dir' => realpath($this->getParameter('kernel.root_dir').'/..'),
]);
}
Or in your template:
<div>
{#
* 'myrandom6' Is your cache key identifier, must be unique
* 300 Is the time to live (TTL) before the cache expires and get regenerated
#}
{% cache 'myrandom6' 300 %}
<textarea>
<!-- Some heavy stuff like Doctrine Lazy Entities -->
{% for i in 1..1000 %}{{ random() }}{% endfor %}
</textarea>
{% endcache %}
</div>
As of the V3, some command-line tools were introduced, mostly for CRUD-like operations.
php bin/console phpfastcache:get filecache cacheKey
This will display the content of a cache item if it eventually exists.
php bin/console phpfastcache:get filecache cacheKey '{"a": 14}' 300 -a 1
This will set the content of a cache item.
The TTL (300), in seconds, is optional and take the default value filled in your configuration file.
The auto-type-cast
option "-a" (enabled by default) will let allows you to automatically type cast your variable:
false
andtrue
will be respectively converted to boolean.1337
and1337.666
will be respectively be converted to integer or float.null
will be converted to null.{"a": 14}
will be converted to an associative array using a JSON detectiona regular string
will remains unchanged and stays a string
You can obviously disable this behavior by turning off the auto-type-cast
option: -a 0
php bin/console phpfastcache:del filecache cacheKey
This will delete the specified cache item.
php bin/console phpfastcache:clear filecache
# OR to clear every caches:
php bin/console phpfastcache:clear
This will clear a single cache instance if specified or all the configured cache instances otherwise.
As of the V3 there's a new, easier and cleaner way to setup HTTP cache to decrease your server bandwidth along with your CPU load: Cacheable Responses. And it's pretty easy to implement:
/**
* @Route("/cached", name="cached")
*/
public function cachedAction(Phpfastcache $phpfastcache, Request $request): Response
{
return (new CacheableResponse($phpfastcache->get('filecache'), $request))->getResponse('cache_key', 3600, function () {
return new Response('Random bytes: ' . \random_bytes(255));
});
}
CacheableResponse
is provided by \Phpfastcache\Bundle\Response\CacheableResponse
.
This class will handle responses headers (cache-control, etag, etc...) and http status (304 Not modified).
