はじめに
こんにちは。だい（@ishidad2）です。
晴れ時々SymbolということでSymbolネタの記事を書いていこうと思います。
今回は@nem_takanobu(Taka Nobu)さんが公開されているtsunagi-functionsを使ってPHPからトランザクションを飛ばしてみようと思います。
ちなみに、PHPから飛ばす書いたのですが色々な諸事情あり、Laravel10を使って試してみました。
なお、Lravel10のインストール方法などは割愛させてもらいます。
それでは行ってみましょう！
Base32 ライブラリのインストール
SymbolHelpers関数内でBase32ライブラリを使うのでインストールしておきます。
composer require christian-riesen/base32
app/Helpers/SymbolHelpers.phpを作成
ソースコード
<?php
namespace App\Helpers;
use Base32\Base32;
class SymbolHelpers
{
public static function loadCatjson($tx, $network)
{
$jsonFile = '';
if ($tx["type"] === "AGGREGATE_COMPLETE" || $tx["type"] === "AGGREGATE_BONDED") {

長いので折りたたんでいます。(ここのコードをヘルパー用に修正しました。Claudeくんが...ｗ)
オートロードの設定
composer.jsonファイルを開き、"autoload" セクションに以下を追加します。
既に記載がある場合は変更しなくてOKです。
"autoload": {
"psr-4": {
"App\\": "app/"
}
}
オートローダーを更新
ターミナルで以下のコマンドを実行して、オートローダーを更新します。
$ composer dump-autoload
ヘルパー関数をインポート
これらのヘルパー関数を使用したい場所で、以下のようにクラスをインポートします。
use App\Helpers\SymbolHelpers;
関数を呼び出す際は、以下のように静的メソッドとして使用します。
$layout = SymbolHelpers::loadLayout($tx1, $catjson, false);
$prepared_tx = SymbolHelpers::prepareTransaction($tx1, $layout, $network);
$parsed_tx = SymbolHelpers::parseTransaction($prepared_tx, $layout, $catjson, $network);
やってみる
コマンドを作って試してみたいと思います。

$this->error("Stack trace:");
$this->error($e->getTraceAsString());
return 1;
}
}
}
実行
実行方法は以下の通りです。
$ php artisan app:send-transaction <private_key> <recipient_address> <amount> [<message>]
private_keyの部分は少しコツ必要で（こちらに書いてるある通り）php sodiumの仕様でSecretkeyが sign_secret + sign_public という構成をとっています。
実際のコマンドは以下のようになります。
$ php artisan app:send-transaction ED949592C90CA58A16CB5BEC303DB011A48373063DDB0C4CFD6DFD01F14A9007D47E477DA7CAE6127779523270F91BD000D7D0E06DA56192FE911460DC39081C TA3KA2ZLNBFRQZUYBRRODVI6236L5T2SFOG7JGI 1000000 "Hello PHP! Welcome to Symbol world!"
今回はテスト用に秘密鍵を載せていますが秘密鍵は絶対に公開しないでください。

もし、トランザクションの内容にエラーがある場合はhttp://sym-test-03.opening-line.jp:3000/transactionStatus/[hash]を調べてみてください。
成功したら以下のようなトランザクションが記録されます。
最後に
今回はLaravelのバックエンドでSymbolトランザクションを実行したかったので試してみましたが、なかなかいい感じにできました。
途中、デッドラインがうまく指定できていなかったり、catjsonの指定が古いままでエラーが発生して進まないなど色々と壁にぶつかりましたが無事トランスファートランザクションが送信できたのでよかったです。
引き続き、複雑なトランザクションも試してみたいと思います。
