コード:

1.エントリーファイル(index.php)

リーリー

機能 1. デバッグモードかどうかを設定します (デバッグモード、つまり APP_DEBUG が True の場合、最後にコンパイルされた ~runtime.php は読み込まれません。開発の場合はデバッグモードで開始することをお勧めします)

2. APP_PATHのパスを定義します

3. これが最も重要でもあります。ここから、複雑だが単純な TP フレームワークの旅が正式に始まります。

TPのソースコードに従い、TPを変更せずにページがどのように表示されるかを紹介します

(追伸: TP フレームワークを学ぶのは初めてで、PHP も学び始めたばかりなので、自分の考えを整理するためにここに私自身の経験をいくつか書き留めたいと思います。また、皆さんのお役に立てれば幸いです。間違いがあれば、教えていただければ幸いです)
