Zilack is a feature rich lightweight Slack bot client written in PHP. The main purpose of it is to provide easy to use client with minimal configuration.


Zilack is avalaible on Packagist and can be installed with Composer

composer require zilkil/zilack

That's pretty much it. Now you can use Zilack in your scripts.



Zilack uses Yaml configuration file to get required settings. You need to load this file right after instansiating the bot. Here's an example of it:

  webhooks_enabled: 1
  webhooks_listener_port: 8081

      name: 'Primary Identity'
      icon: 'robot_face'
      name: 'Burger Identity'
      icon: 'hamburger'

Main script

In order to use Zilack's features, you need to load it into your scripts. Here's an example of index.php which instanciates the bot.

require 'vendor/autoload.php';

//Instantiating the bot itself
$bot = new \Zilack\ZilackBot();

//Loading your configuration file

//Registering bot commands and webhooks
    ->register(new \Zilack\SampleCommands\ExtendedResponseCommand())
    ->register(new \Zilack\SampleCommands\RegularResponseCommand())
    ->register(new \Zilack\SampleCommands\PrivateResponseCommand())
    ->register(new \Zilack\SampleCommands\IdentityResponseCommand())
    ->register(new \Zilack\SampleWebhooks\DumperWebhook());
//Starting the bot    


Zilack currently supports two type of components - commands and incoming webhooks.


Commands are triggered by specific keyword detected in user message in Slack chat. There is no naming restrictions on Zilack for commands, however, you need to make sure that you are able to type that keyword in chat. Recommended naming would be !my:command. Bellow is an example of !hello command which triggers bot response Hello there!

class HelloCommand extends ZilackCommand
    public function configure()

    public function execute($message, $context, $commandName)
        $this->getClient()->sendResponse($this->getChannel(), 'Hello there!');

Sample Commands

There's a variety of sample commands in \Zilack\SampleCommands namespace. These commands are written to familiarize you with various possible response types and usage of different configurations.

Command Trigger Description
RegularResponseCommand !response:regular Provides an example of regular response sent back to Slack
ExtendedResponseCommand !response:extended Provides an example of response with overwritten bot user name and icon without using identities configuration
IdentityResponseCommand !response:identity Provides an example of identities usage to overwrite default bot user name and icon
PrivateResponseCommand !response:private Provides an example of private response sent to user who triggered the command


Zilack has less control over incoming webhooks that over commands as they are too dynamic to handle them universally. Thus, incoming webhook events are triggered to all listeners and there must be a filter implementation to identify if webhook is correct.
