我尝试使用 Homebrew ( https://formulae.brew.sh/formula/php ) 在 macOS 上安装 PHP，但每次都会出现以下错误：
Warning: No available formula or cask with the name "php".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.
使用时brew search php我只能找到phpstorm和eclipse-php。为什么我无法使用 Homebrew 在 macOS 上找到或安装 PHP？提前致谢！
旁注：我已经将 Homebrew 更新到最新版本并在 GitHub 上检查了公式，上次提交是 6 天前https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/php.rb
