A high-performance backend cache system. It is intended for use in speeding up dynamic web applications by alleviating database load. Well implemented, it can drops the database load to almost nothing, yielding faster page load times for users, better resource utilization. It is simple yet powerful.

As the V9 is relatively not compatible with previous versions, please read carefully the migration guide to ensure you the smoothest migration possible. One of the biggest change is the configuration system which is now an object that replace the primitive array that we used to implement back then. Also, please note that the V9 requires at least PHP 8 or higher to works properly.

🆕 in V8: Multiple strategies ($strategy
) are now supported for tagging:

allows you to get cache item(s) by at least ONE of the specified matching tag(s). Default behavior.TaggableCacheItemPoolInterface::TAG_STRATEGY_ALL
allows you to get cache item(s) by ALL of the specified matching tag(s) (the cache item can have additional tag(s))TaggableCacheItemPoolInterface::TAG_STRATEGY_ONLY
allows you to get cache item(s) by ONLY the specified matching tag(s) (the cache item cannot have additional tag(s))It also supports multiple calls, Tagging, Setup Folder for caching. Look at our examples folders for more information.
Phpfastcache provides a class that gives you basic information about your Phpfastcache installation
Phpfastcache\Api::GetVersion();
Phpfastcache\Api::getChangelog();
Phpfastcache\Api::getPhpfastcacheVersion();
Phpfastcache\Api::getPhpfastcacheChangelog();
😅 Good news, as of the V6, a Psr16 adapter is provided to keep the cache simplest using very basic getters/setters:
get($key, $default = null);
set($key, $value, $ttl = null);
delete($key);
clear();
getMultiple($keys, $default = null);
setMultiple($values, $ttl = null);
deleteMultiple($keys);
has($key);
Basic usage:
<?php
use Phpfastcache\Helper\Psr16Adapter;
$defaultDriver = 'Files';
$Psr16Adapter = new Psr16Adapter($defaultDriver);
if(!$Psr16Adapter->has('test-key')){
// Setter action
$data = 'lorem ipsum';
$Psr16Adapter->set('test-key', 'lorem ipsum', 300);// 5 minutes
}else{
// Getter action
$data = $Psr16Adapter->get('test-key');
}
/**
* Do your stuff with $data
*/
Internally, the Psr16 adapter calls the Phpfastcache Api via the cache manager.
📣 As of the V6, Phpfastcache provides an event mechanism. You can subscribe to an event by passing a Closure to an active event:
<?php
use Phpfastcache\EventManager;
/**
* Bind the event callback
*/
EventManager::getInstance()->onCacheGetItem(function(ExtendedCacheItemPoolInterface $itemPool, ExtendedCacheItemInterface $item){
$item->set('[HACKED BY EVENT] ' . $item->get());
});
An event callback can get unbind but you MUST provide a name to the callback previously:
<?php
use Phpfastcache\EventManager;
/**
* Bind the event callback
*/
EventManager::getInstance()->onCacheGetItem(function(ExtendedCacheItemPoolInterface $itemPool, ExtendedCacheItemInterface $item){
$item->set('[HACKED BY EVENT] ' . $item->get());
}, 'myCallbackName');
/**
* Unbind the event callback
*/
EventManager::getInstance()->unbindEventCallback('onCacheGetItem', 'myCallbackName');
🆕 As of the V8 you can simply subscribe to every events of Phpfastcache.
More information about the implementation and the events are available on the Wiki
📚 As of the V6, Phpfastcache provides some helpers to make your code easier.
May more will come in the future, feel free to contribute !
Check out the WIKI to learn how to implement aggregated cache clustering feature.
composer require phpfastcache/phpfastcache
<?php
use Phpfastcache\CacheManager;
use Phpfastcache\Config\ConfigurationOption;
// Setup File Path on your config files
// Please note that as of the V6.1 the "path" config
// can also be used for Unix sockets (Redis, Memcache, etc)
CacheManager::setDefaultConfig(new ConfigurationOption([
'path' => '/var/www/phpfastcache.com/dev/tmp', // or in windows "C:/tmp/"
]));
// In your class, function, you can call the Cache
$InstanceCache = CacheManager::getInstance('files');
/**
* Try to get $products from Caching First
* product_page is "identity keyword";
*/
$key = "product_page";
$CachedString = $InstanceCache->getItem($key);
$your_product_data = [
'First product',
'Second product',
'Third product'
/* ... */
];
if (!$CachedString->isHit()) {
$CachedString->set($your_product_data)->expiresAfter(5);//in seconds, also accepts Datetime
$InstanceCache->save($CachedString); // Save the cache item just like you do with doctrine and entities
echo 'FIRST LOAD // WROTE OBJECT TO CACHE // RELOAD THE PAGE AND SEE // ';
echo $CachedString->get();
} else {
echo 'READ FROM CACHE // ';
echo $CachedString->get()[0];// Will print 'First product'
}
/**
* use your products here or return them;
*/
echo implode('<br />', $CachedString->get());// Will echo your product list
* See the file examples/withoutComposer.php for more information.
Please include Phpfastcache through composer by running composer require phpfastcache/phpfastcache
.
