#### :warning: Please note that the V9 is mostly a PHP 8 type aware update of Phpfastcache with some significant changes !
> As the V9 is **relatively** not compatible with previous versions, please read carefully the [migration guide](./docs/migration/MigratingFromV8ToV9.md) to ensure you the smoothest migration possible.
One of the biggest changes 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.

\* Driver descriptions available in [DOCS/DRIVERS.md](./docs/DRIVERS.md)
:new: As of v9.2 a new Couchbase extension has been released: [Couchbasev4](https://github.com/PHPSocialNetwork/couchbasev4-extension)
Also a new driver extension has been added: `Ravendb`. The driver will be **actively developed** in the feature to allow better fine-grained configuration.
This new extension **is the beginning of a new era** for Phpfastcache along with some others:\
Many drivers has been moved from the core to their own sub-repository as a standalone extension: `Arangodb`, `Couchdb`, `Dynamodb`, `Firestore`, `Mongodb`, `Solr`.\
They can be easily added through composer, ex: `composer install phpfastcache/couchbasev4-extension`
However `Couchbasev3` **will stay in the core** for compatibility reasons but will be deprecated.
---------------------------
Because caching does not mean weaken your code
---------------------------
Phpfastcache has been developed over the years with 3 main goals:
- Performance: We optimized and still optimize the code to provide you the lightest library as possible
- Security: Because caching strategies can sometimes comes with unwanted vulnerabilities, we do our best to provide you a sage & strong library as possible
- Portability: No matter what operating system you're working on, we did our best to provide you the most cross-platform code as possible
---------------------------

- `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 versioning API
Phpfastcache provides a class that gives you basic information about your Phpfastcache installation
- Get the API version (Item+Pool interface) with `Phpfastcache\Api::GetVersion();`
- Get the API changelog (Item+Pool interface) `Phpfastcache\Api::getChangelog();`
- Get the Phpfastcache version with `Phpfastcache\Api::getPhpfastcacheVersion();`
- Get the Phpfastcache changelog `Phpfastcache\Api::getPhpfastcacheChangelog();`
---------------------------
Want to keep it simple ?
---------------------------
:sweat_smile: 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
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.
---------------------------
Introducing to events
---------------------------
:mega: As of the V6, Phpfastcache provides an event mechanism.
You can subscribe to an event by passing a Closure to an active event:
```php
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
onCacheGetItem(function(ExtendedCacheItemPoolInterface $itemPool, ExtendedCacheItemInterface $item){
$item->set('[HACKED BY EVENT] ' . $item->get());
}, 'myCallbackName');
/**
* Unbind the event callback
*/
EventManager::getInstance()->unbindEventCallback('onCacheGetItem', 'myCallbackName');
```
:new: As of the **V8** you can simply subscribe to **every** event of Phpfastcache.
More information about the implementation and the events are available on the [Wiki](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV6%CB%96%5D-Introducing-to-events)
---------------------------
Introducing new helpers
---------------------------
:books: As of the V6, Phpfastcache provides some helpers to make your code easier.
- (:warning: Removed in v8, [why ?](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV6%CB%96%5D-Act-on-all-instances)) ~~The [ActOnAll Helper](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV6%CB%96%5D-Act-on-all-instances) to help you to act on multiple instance at once.~~
- The [CacheConditional Helper](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV6%CB%96%5D-Cache-Conditional) to help you to make the basic conditional statement more easier.
- The [Psr16 adapter](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV6%CB%96%5D-Psr16-adapter)
May more will come in the future, feel free to contribute !
---------------------------
Introducing aggregated cluster support
---------------------------
Check out the [WIKI](https://github.com/PHPSocialNetwork/phpfastcache/wiki/%5BV8%CB%96%5D-Aggregated-cache-cluster) to learn how to implement aggregated cache clustering feature.
---------------------------
As Fast To Implement As Opening a Beer
---------------------------
#### :thumbsup: Step 1: Include phpFastCache in your project with composer:
```bash
composer require phpfastcache/phpfastcache
```
#### :construction: Step 2: Setup your website code to implement the phpFastCache calls (with Composer)
```php
'/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('
', $CachedString->get());// Will echo your product list
```
#### :zap: Step 3: Enjoy ! Your website is now faster than lightning !
For curious developers, there is a lot of other examples available [here](./docs/examples).
#### :boom: Phpfastcache support
