SDK of the LINE Messaging API for PHP.

Please refer to the official API documents for details.

en: https://devdocs.line.me/en/

ja: https://devdocs.line.me/ja/

The LINE messaging API SDK can be installed with Composer.

$ composer require linecorp/line-bot-sdk

Instance of bot client is a handler of the Messaging API.

$httpClient = new \LINE\LINEBot\HTTPClient\CurlHTTPClient('<channel access token>');
$bot = new \LINE\LINEBot($httpClient, ['channelSecret' => '<channel secret>']);

The constructor of bot client requires an instance of HTTPClient. This library provides CurlHTTPClient as default.

You can call API through the bot client instance.

Deadly simple sample is following;

$response = $bot->replyText('<reply token>', 'hello!');

This procedure sends a message to the destination that is associated with <reply token>.

More advanced sample is below;

$textMessageBuilder = new \LINE\LINEBot\MessageBuilder\TextMessageBuilder('hello');
$response = $bot->replyMessage('<reply token>', $textMessageBuilder);
if ($response->isSecceeded()) {
    echo 'Succeeded!';
    return;
}

// Failed
echo $response->getHTTPStatus . ' ' . $response->getBody();

LINEBot#replyMessage() takes reply token and MessageBuilder. This method sends message that is built by MessageBuilder to the destination.

Type of message depends on the type of instance of MessageBuilder. That means this method sends text message if you pass TextMessageBuilder, on the other hand it sends image message if you pass ImaageMessageBuilder.

If you want detail information of MessageBuilder, please refer \LINE\LINEBot\MessageBuilder and the namespace.

Other methods that take MessageBuilder behave the same.

Methods that call API returns Response. Response has three methods;

• Response#isSucceeded()
• Response#getHTTPStatus()
• Response#getBody()

You can use these method to check response status and take response body.

This method returns the boolean value. Return value represents "request is succeeded or not".

This method returns the HTTP status code of response.

This method returns the body of response as string.

LINE's server sends user action (message, image, location and etc.) to your bot server. Request of that contains event(s); event is action of the user.

Flow of webhook handling is like following;

1. Receive webhook from LINE's server.
2. Parse request payload by LINEBot#parseEventRequest($body, $signature).
3. Iterate parsed events and some react as you like.

We provides examples of this flow:

• EchoBot: Route.php
• KitchenSink: Route.php

Please check official API documents and PHPDoc. If you first time to use this library, we recommend to see examples and PHPDoc of \LINE\LINEBot.

This repository contains two examples of LINE Messaging API.

A simple sample implementation. This application reacts to text message that is from user.

A full-stack (and a bit complex) sample implementation. That will show you practical usage of LINE Messaging API.

This library provides PHPDoc. That will helps you to know usages of methods.

This library can generate pretty documents by apigen. Please try:

$ make doc

When HTML documents will be put on docs/.

Official API documents shows the detail of Messaging API and fundamental usage of SDK.

1. Implement \LINE\LINEBot\HTTPClient
2. Pass the implementation to the constructor of \LINE\LINEBot

Please refer CurlHTTPClient that is the default HTTP client implementation.

• PHP 5.6 or later

Please use make test.

Please use make phpcs.

Please use make phpmd.
