The instructions for using Predis is outdated. It should be the following:

$adapter = new PredisAdapter((new \Predis\Client('localhost')));

Your username is touhonoob, your README.md says to use PalePurple

use \PalePurple\RateLimit\RateLimit;
use \PalePurple\RateLimit\Adapter\APC as APCAdapter;
use \PalePurple\RateLimit\Adapter\Redis as RedisAdapter;
use \PalePurple\RateLimit\Adapter\Predis as PredisAdapter;
use \PalePurple\RateLimit\Adapter\Memcached as MemcachedAdapter;
use \PalePurple\RateLimit\Adapter\Stash as StashAdapter;

But the github.io site linked gives examples using touhonoob.

use \Touhonoob\RateLimit\RateLimit;
use \Touhonoob\RateLimit\Adapter\APC as RateLimitAdapterAPC;
use \Touhonoob\RateLimit\Adapter\Redis as RateLimitAdapterRedis;

And it seems that both the packages palepurple/ratelimit and touhonoob/ratelimit exist for composer. So what do I do?

I've tried creating a rate limit that only allows 1 request every 5 seconds, but i seem to always get 0 back from ->check(.

I have php-apcu installed and am using php-7.1.

My Code:

<?php

require 'vendor/autoload.php';

use \Touhonoob\RateLimit\RateLimit;
use \Touhonoob\RateLimit\Adapter\APCu as RateLimitAdapterAPCu;

$adapter = new RateLimitAdapterAPCu(); // Use APCu as Storage
$rateLimit = new RateLimit("myratelimit", 1, 5, $adapter); // 1 Requests / 5 seconds

$id = $_SERVER['REMOTE_ADDR']; // Use client IP as identity
if ($rateLimit->check($id) > 0) { // This always returns 0 so it's always exceeded?
  echo "passed";
} else {
  echo "rate limit exceeded";
}

The instructions for using Predis is outdated. It should be the following:

$adapter = new PredisAdapter((new \Predis\Client('localhost')));

$adapter = new RateLimitAdapterRedis();
$rateLimit = new RateLimit("myratelimit", 1, 3600, $adapter);

$id = 'foo';

if ($rateLimit->check($id) > 0) {
    echo "passed";
} else {
    echo "rate limit exceeded";
}

When I run this snippet I got "rate limit exceeded" message at first request.

I am using this in my Slim application as middleware.

For some reason, some of the requests get passed the "firewall".

Hi @touhonoob ,
Great work! I am just having a problem while setting this up. I am using this configuration and soemtime it's working and sometimes it not.

$limit_adapter = new PredisAdapter((new \Predis\Client('localhost')));
$rateLimit = new RateLimit("limit2", 100, 360, $limit_adapter); 
if(!empty($_SESSION['admin_id'])){
	$id = $_SESSION['admin_id']; 
}else{
	$id = $_SERVER['REMOTE_ADDR'];
}  
if($rateLimit->check($id)) {
	// passed
}else{ 
	 header('HTTP/1.1 429 Too many requests', true, 429);
}

When a user is blocked and he keeps reloading that tab. Then sometimes user gets passed and sometimes not passed even if the user is blocked. I don't know why this is happening can you please help me with that?

Thanks,
Rohit Kumar

I cant use this on my PHP 7 install as it does not support APCu

I ran a quick test and seems allowance won't be handled correctly under concurrency.

Now if I have already configured and connected Redis client, I need to create new and connect at RateLimitAdapterRedis
My idea is using prepared and connected Redis client such as:

$redis = new Redis();
$redis->pconnect('1.2.3.4', 6379);

$adapter = new RateLimitAdapterRedis($redis);
$rateLimit = new RateLimit("myratelimit", 100, 3600, $adapter);

@touhonoob what do you think about it? I can PR this, if you need.
