evoluted / php-ratelimiter example snippets

// 1. Make a rate limiter with limit 3 attempts in 10 minutes
$cacheAdapter = new DesarrollaCacheAdapter((new DesarrollaCacheFactory())->make());
$ratelimiter = new RateLimiter(new ThrottlerFactory(), new HydratorFactory(), $cacheAdapter, 3, 600);

// 2. Get a throttler for path /login 
$loginThrottler = $ratelimiter->get('/login');

// 3. Register a hit
$loginThrottler->hit()

// 4. Check if it reached the limit
if ($loginThrottler->check()) {
    // access permitted
} else {
    // access denied
}

// Or combine the steps 3 & 4
if ($loginThrottler->access()) {
    // access permitted
} else {
    // access denied
}

// To get the number of hits
print $loginThrottler->count(); // or count($throttler)
