Not a "Traditional" Caching

phpFastCache is not a traditional caching method which is keep read and write to files, sqlite or mass connections to memcache, redis, mongodb... Also, when you use Memcache / Memcached, your missed hits will be reduced. Different with normal caching methods which shared everywhere on internet, phpFastCache Lib reduce the high I/O load, and faster than traditional caching method at least x7 ~+ times. However, some time you still want to use traditional caching, we support them too.

use phpFastCache\CacheManager;

CacheManager::getInstance('files', $config);
// An alternative exists:
CacheManager::Files($config);

Reduce Database Calls

Your website have 10,000 visitors who are online, and your dynamic page have to send 10,000 same queries to database on every page load. With phpFastCache, your page only send 1 query to DB, and use the cache to serve 9,999 other visitors.

As Fast To Implement As Opening a Beer

👍 Step 1: Include phpFastCache in your project with composer:

composer require phpFastCache/phpFastCache

🚧 Step 2: Setup your website code to implements phpFastCache bits (With Composer)

use phpFastCache\CacheManager;

// Setup File Path on your config files
CacheManager::setup(array(
    "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'
    // etc...
];

if (is_null($CachedString->get())) {
    $CachedString->set($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 prints 'First product'
}

/**
 * use your products here or return it;
 */
echo implode('<br />', $CachedString->get());// Will echo your product list

💾 Legacy / Lazy Method (Without Composer)

• See the file examples/legacy.php for more information.

⚡ Step 3: Enjoy ! Your website is now faster than flash !

For curious developpers, there is a lot of others available examples here.
