[Tip] Fluent Slack Message Builder

Hey,

Just a little class for people who need to send Slack messages from their code:

class SlackMessageBuilder
{
    /**
     * The message.
     *
     * @var string
     */
    private $message = "";

    /**
     * The room to post to.
     *
     * @var string
     */
    private $room = "";

    /**
     * The username to post as.
     *
     * @var string
     */
    private $username = "iDiscuss Bot";

    /**
     * The emoji to use for the bot.
     *
     * @var string
     */
    private $emoji = ":bell:";

    /**
     * The endpoint to send requests to.
     *
     * @var string
     */
    private $endpoint = "";

    /**
     * Set the message.
     *
     * @param string $message
     * @return SlackMessageBuilder
     */
    public function setMessage($message)
    {
        $this->message = $message;
        return $this;
    }

    /**
     * Set the room to post to.
     *
     * @param string $room
     * @return SlackMessageBuilder
     */
    public function setRoom($room)
    {
        $this->room = $room;
        return $this;
    }

    /**
     * Set the username to post as.
     *
     * @param string $username
     * @return SlackMessageBuilder
     */
    public function setUsername($username)
    {
        $this->username = $username;
        return $this;
    }

    /**
     * Set the emoji to use for the bot.
     *
     * @param string $emoji
     * @return SlackMessageBuilder
     */
    public function setEmoji($emoji)
    {
        $this->emoji = $emoji;
        return $this;
    }

    /**
     * Set the endpoint to send requests to.
     *
     * @param string $endpoint
     * @return SlackMessageBuilder
     */
    public function setEndpoint($endpoint)
    {
        $this->endpoint = $endpoint;
        return $this;
    }

    /**
     * Send the message.
     */
    public function send()
    {
        $data = "payload=" . json_encode([
                "channel"       =>  "#{$this->room}",
                "text"          =>  $this->message,
                "icon_emoji"    =>  $this->emoji,
                "username"      =>  $this->username
            ]);

        // You can get your webhook endpoint from your Slack settings
        $ch = curl_init($this->endpoint);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        $result = curl_exec($ch);
        curl_close($ch);

        return $result;
    }
}

How it can be used:

$message = new SlackMessageBuilder;
        $message->setEmoji(":bell:")
            ->setEndpoint("WEBHOOK URL")
            ->setMessage("MESSAGE")
            ->setRoom("ROOM")
            ->setUsername("USERNAME")
            ->send();

You need to add a new Incoming Webhook on your Slack team for this to work. It does work on development environments!
