PHP Advent Calendar 2020 25日目のエントリです。
24日目は kasyuu さん^[1] の名前で呼べると色々と幸せになれるかもしれないphp関連の用語あれこれでした。読んだのですが覚えて正しく使えるようになりたいと思いました。^[2]

大変便利なんだけど何かと辛い phpenv で、11/26 にリリースされた php 8 をビルドできました。
このくらい (12/25) にはできるようになってそうと思って早々に 11/6 に登録していたのですが、できて良かったです。^[3]

環境情報

実験が成功した環境を記述します。

MacBook Air (Retina, 13-inch, 2020)
- macOS Catalina 10.15.7
phpenv v0.9.0-rc.1
- on anyenv 1.1.2

インストール済みの関連ライブラリ

↓が使用されたはず、と思っています（brew info で確認）

8/10 頃に PHP 7.4 をビルドしようとして悪戦苦闘していたTweetが残っているのですが、PHP 8 をビルドするのに際して追加のライブラリインストールやビルドオプションの調整は必要なかったです。

ちなみに、悪戦苦闘の跡

コケては情報を探す、を繰り返して辿り着いたようです。。
そして、やっと記事になった。。

phpenv で PHP 8 をビルド

実はやっぱり先人がいたようで、macOS に phpenv で PHP 8.0 をインストールする - Qiita を見ちゃってからやりました。
ということで、手順は以下で完了です。

phpenv update (コンソール出力フルバージョン在中)


❯ phpenv -v
phpenv v0.9.0-rc.1

~
❯ phpenv update
warning: Pulling without specifying how to reconcile divergent branches is
discouraged. You can squelch this message by running one of the following
commands sometime before your next pull:

  git config pull.rebase false  # merge (the default strategy)
  git config pull.rebase true   # rebase
  git config pull.ff only       # fast-forward only

You can replace "git config" with "git config --global" to set a default
preference for all repositories. You can also pass --rebase, --no-rebase,
or --ff-only on the command line to override the configured default per
invocation.

ちょっとベンチマーク

すんなりビルドできたので、「これで書ける...」と思い安堵したのですが、これだけだとちょっともの足りないかなと思って PHP 8 のパワーを軽く体感しました。
テキトーに探して拾ったベンチマークプログラムを少し改変して、インストールした素のまま 8.0.0 と 7.4.9 で走らせてみた結果がこちら↓です。

PHP 8.0.0 [平均16秒くらい]

PHP 7.4.9 [平均19秒くらい]

プログラムはこちら。
https://github.com/sogaoh/php_benchmark

3秒差が即出るのはなかなかのパワーかな、という気がします。
（すぐに目に見える結果が出てヨカッタ。。）

なお、7.0.0 や 5.6.39 とも比較できれば、と思ったのですが、この環境では共に BUILD ERROR となってそれはできませんでした。
