README

A developer-friendly wrapper for the LINE Messaging API SDK for PHP.

Phine simplifies common LINE bot operations by providing intuitive message builders, event handlers, and convenient client methods.

Installation

composer require nanato12/phine

Requirements

• PHP >= 8.1
• linecorp/line-bot-sdk ^12.4

Quick Start

use Phine\Client;
use Phine\MessageBuilders\TextMessageBuilder;

$client = new Client($channelSecret, $channelAccessToken);

// Parse incoming webhook request
$events = $client->parseEventRequest($requestBody, $signature);

foreach ($events as $event) {
    $client->setEvent($event);
    $client->reply([new TextMessageBuilder('Hello!')]);
}

Client

The Client class extends MessagingApiApi from the official LINE SDK, so all original methods are available.

$client = new Client($channelSecret, $channelAccessToken);

Message Builders

Phine provides convenient builders for creating LINE messages.

TextMessageBuilder

use Phine\MessageBuilders\TextMessageBuilder;

// Simple text message
$message = new TextMessageBuilder('Hello!');

// With LINE emojis and quote
$message = new TextMessageBuilder(
    text: '$ Hello!',
    emojis: [$emoji],
    quoteToken: 'quote-token'
);

RawFlexMessageBuilder

Build Flex Messages from a JSON array. Useful when designing messages with the Flex Message Simulator.

use Phine\MessageBuilders\RawFlexMessageBuilder;

$json = file_get_contents('flex.json');
$contents = json_decode($json, true);
$message = new RawFlexMessageBuilder($contents, 'Alt text for notifications');

ImageMessageBuilder

use Phine\MessageBuilders\ImageMessageBuilder;

$message = new ImageMessageBuilder(
    originalContentUrl: 'https://example.com/image.jpg',
    previewImageUrl: 'https://example.com/image-preview.jpg'
);

VideoMessageBuilder

use Phine\MessageBuilders\VideoMessageBuilder;

$message = new VideoMessageBuilder(
    originalContentUrl: 'https://example.com/video.mp4',
    previewImageUrl: 'https://example.com/video-thumbnail.jpg',
    trackingId: 'tracking-123' // optional, for tracking video views
);

AudioMessageBuilder

use Phine\MessageBuilders\AudioMessageBuilder;

$message = new AudioMessageBuilder(
    originalContentUrl: 'https://example.com/audio.m4a',
    duration: 60000 // duration in milliseconds
);

StickerMessageBuilder

use Phine\MessageBuilders\StickerMessageBuilder;

$message = new StickerMessageBuilder(
    packageId: '446',
    stickerId: '1988'
);

LocationMessageBuilder

use Phine\MessageBuilders\LocationMessageBuilder;

$message = new LocationMessageBuilder(
    title: 'Tokyo Station',
    address: '1 Chome Marunouchi, Chiyoda City, Tokyo',
    latitude: 35.6812,
    longitude: 139.7671
);

Client Methods

parseEventRequest

Parses the incoming webhook request body and validates the signature.

$events = $client->parseEventRequest($requestBody, $signature);

setEvent

Stores the current event in the client instance. Required before calling reply().

$client->setEvent($event);

reply

Sends a reply message to the user. Must call setEvent() first.

// Simple reply
$client->reply([new TextMessageBuilder('Hello!')]);

// With sender icon and quick reply buttons
$client->reply($messages, $sender, $quickReply);

push

Sends a push message to a specific user, group, or room.

$client->push($userId, [new TextMessageBuilder('Hello!')]);

// With sender and quick reply
$client->push($userId, $messages, $sender, $quickReply);

sendMulticast

Sends a message to multiple users at once (up to 500 users).

$userIds = ['U1234...', 'U5678...'];
$client->sendMulticast($userIds, [new TextMessageBuilder('Hello everyone!')]);

sendBroadcast

Sends a message to all users who have added your bot as a friend.

$client->sendBroadcast([new TextMessageBuilder('Announcement!')]);

getProfileFromUserID

Retrieves a user's profile. Automatically uses the appropriate API based on the event source (user, group, or room).

$profile = $client->getProfileFromUserID($userId);

echo $profile->displayName;
echo $profile->pictureUrl;
echo $profile->statusMessage; // Only available for 1:1 chats

Event Handlers

Phine provides an event handling system to organize your bot logic.

BaseEventHandler

Create handlers for specific event types:

use LINE\Webhook\Model\Event;
use LINE\Webhook\Model\MessageEvent;
use LINE\Webhook\Model\TextMessageContent;
use Phine\Client;
use Phine\Handlers\BaseEventHandler;
use Phine\MessageBuilders\TextMessageBuilder;

class TextMessageHandler extends BaseEventHandler
{
    public const EVENT_CLASS = MessageEvent::class;
    public const MESSAGE_TYPE_CLASS = TextMessageContent::class;
    // Optional: public const MESSAGE_SOURCE_CLASS = GroupSource::class;

    public function handle(Client $client, Event $event): void
    {
        $client->reply([new TextMessageBuilder('Message received!')]);
    }
}

BaseCommandHandler

Create handlers that respond to specific text commands:

use LINE\Webhook\Model\Event;
use Phine\Client;
use Phine\Handlers\BaseCommandHandler;
use Phine\MessageBuilders\TextMessageBuilder;

class HelloHandler extends BaseCommandHandler
{
    public static function commands(): array
    {
        return ['hello', 'hi', 'hey'];
    }

    public function handle(Client $client, Event $event): void
    {
        $client->reply([new TextMessageBuilder('Hello!')]);
    }
}

For commands with arguments, use prefix matching:

class SearchHandler extends BaseCommandHandler
{
    public static function commands(): array
    {
        return ['search '];
    }

    public static function isPrefix(): bool
    {
        return true; // Matches "search foo", "search bar", etc.
    }

    public function handle(Client $client, Event $event): void
    {
        /** @var MessageEvent $event */
        /** @var TextMessageContent $message */
        $message = $event->getMessage();
        $keyword = substr($message->getText(), 7); // Remove "search "

        // Search logic here...
    }
}

EventDispatcher

Register and dispatch events to your handlers:

use Phine\Handlers\EventDispatcher;

class BotDispatcher extends EventDispatcher
{
    public function getHandlerClasses(): array
    {
        return [
            TextMessageHandler::class,
            HelloHandler::class,
            SearchHandler::class,
        ];
    }
}

// In your webhook endpoint
$events = $client->parseEventRequest($body, $signature);

foreach ($events as $event) {
    BotDispatcher::dispatch($client, $event);
}
