将PHP 7.0升级至7.1
参考）在MacOSX上，可以使用brew install php命令将版本升级到7.1。

大致步骤
由于之前已经通过brew安装了PHP7.0，所以这次不需要添加存储库。
-
brew update
brew upgrade
brew search php ※いちおうあるか確認しておく
brew unlink php70
brew install php71
以中文为母语的方式进行再表述：进行安装。
$ brew install php71
==> Installing php71 from homebrew/php
==> Downloading https://homebrew.bintray.com/bottles-php/php71-7.1.6_18.yosemite.bottle.tar.gz

==> Pouring php71-7.1.6_18.yosemite.bottle.tar.gz
==> Caveats
The php.ini file can be found in:
/usr/local/etc/php/7.1/php.ini
✩✩✩✩ Extensions ✩✩✩✩
If you are having issues with custom extension compiling, ensure that you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:
PATH="/usr/local/bin:$PATH"
PHP71 Extensions will always be compiled against this PHP. Please install them using --without-homebrew-php to enable compiling against system PHP.
✩✩✩✩ PHP CLI ✩✩✩✩
If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc, ~/.zshrc, ~/.profile or your shell's equivalent configuration file:
export PATH="$(brew --prefix homebrew/php/php71)/bin:$PATH"
✩✩✩✩ FPM ✩✩✩✩
To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php71/homebrew.mxcl.php71.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php71.plist
The control script is located at /usr/local/opt/php71/sbin/php71-fpm
OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:
PATH="/usr/local/sbin:$PATH"
You may also need to edit the plist to use the correct "UserName".
Please note that the plist was called 'homebrew-php.josegonzalez.php71.plist' in old versions of this formula.
With the release of macOS Sierra the Apache module is now not built by default. If you want to build it on your system you have to install php with the --with-httpd24 option. See brew options php71 for more details.
To have launchd start homebrew/php/php71 now and restart at login:
brew services start homebrew/php/php71

? /usr/local/Cellar/php71/7.1.6_18: 349 files, 40MB
顺便说一句，在我搜索 php 时，也找到了 php72，但因为它仍处于α版阶段，所以我决定不安装它。
确认 (què
嗯，我觉得应该没有无法安装的问题。
$ php -v

好的。没问题。
我在一个使用以下框架的个人现有项目中进行了轻量级的操作确认，没有遇到任何问题。

CodeIgniter 4dev
CodeIgniter 2.x （フレームワークのコアは昨年PHP7.0最適化済み）
随后
去年安装了PHP7.0之后，我忘记了如何修改php.ini文件和安装了哪些扩展模块，所以可能不需要，不过还是要确认一下。

有些项目似乎没有特别进行修改。
opcache的启用/禁用设置发生了变化，但是我不记得PHP7.0最初是禁用的还是我自己禁用的。（也没有查过）
暂时来说，我刚刚才意识到我没有正确设置时区…

扩展模块
我查看了 PHP 7.0 的扩展模块，但只安装了 Apache 模块。（虽然我记得还安装了其他模块…）
$ tree /usr/local/Cellar/php70/7.0.7/libexec/
/usr/local/Cellar/php70/7.0.7/libexec/
└── apache2
└── libphp7.so
在本地开发时，我使用内置服务器，因此 apache 模块只在需要时安装。
