4. 今日はブラウザでPHPを実行する方法を 紹介します
6. サーバーにPOSTしない
7. ソースコード https://github.com/OHMORIYUSUKE/php-web 7
8. サーバー側で実行したい場合は、 プログラミング＆実行 できるWEBアプリを手作り PyCon Kyushu 2024 KAGOSHIMA を見てください！

11. Next.jsのClient-side Renderingで PHPを動かしていく
12. Client-side Rendering とは
13. Client-side Rendering とは Reactによるクライアント・サイド・レンダリング（CSR） では、ブラウザは最小限のHTMLページと、そのページに必 要なJavaScriptをダウンロードする。 In Client-Side Rendering (CSR) with React, the browser downloads a minimal HTML page and the JavaScript needed for the page. Client-side Rendering (CSR) https://nextjs.org/docs/pages/building-your-application/rendering/client-side-r endering
14. 作る
15. これを作る！ - テキストエリアにPHP のコードを入力 - [Run PHP]のボタンを 押下 - 実行結果が表示される

24. php-wasm とは PHPをWebAssembly（Wasm）上で動作させるための技術で す。これにより、ブラウザ上でPHPコードを実行することが 可能になります。 https://github.com/seanmorris/php-wasm
25. WebAssembly（Wasm） とは
26. WebAssembly（Wasm） とは WebAssembly は現代のウェブブラウザーで実行できる新し い種類のコードです。ネイティブに近いパフォーマンスで動 作する、コンパクトなバイナリー形式の低レベルなアセンブ リー風言語です。さらに、 C/C++、C# や Rust などの言語 のコンパイル先となり、それらの言語をウェブ上で実行する ことができます。 WebAssembly は JavaScript と並行して 動作するように設計されているため、両方を連携させること ができます。 WebAssembly https://developer.mozilla.org/ja/docs/WebAssembly

51. リッチなエディターにしてみる
52. @monaco-editor/react
53. @monaco-editor/react とは Monaco Editor は、Microsoft がオープンソースとして開発 しているコードエディターです。Monaco Editor は VSコー ドを動かすコード・エディターです。 Monaco Editor を React で簡単に扱えるようにしたラッパー です。 https://monaco-react.surenatoyan.com/
54. 使い方
55. "use client"; import React from "react"; import Editor from "@monaco-editor/react"; const PHPWasmComponent: React.FC = () => { return ( <Editor height="100%" width="50%" language="php" theme="vs-dark" /> ); }; export default PHPWasmComponent; これだけです
56. Visual Studio Code のようなエディタを Web に組み込めます https://monaco-react.surenatoyan.com/
57. Ruby を Next.js で実行するのもあるので 見てください！
