This example uses the PSR6 cache pool redis-adapter. See http://www.php-cache.com/ for alternatives.

require_once 'vendor/autoload.php';
use Cache\Adapter\Redis\RedisCachePool;
$client = new \Redis();
$client->connect('127.0.0.1', 6379);
// Create a PSR6 cache pool
$pool = new RedisCachePool($client);
$client = new \Github\Client();
$client->addCache($pool);
// Do some request
// Stop using cache
$client->removeCache();
Using cache, the client will get cached responses if resources haven't changed since last time,
without reaching the X-Rate-Limit
imposed by GitHub.
