原因は、久しぶりになったx-codeのアップデートが原因で、実行できなくなっていた。 以下のコマンドでx-codeをインストール

xcode-select --install

すると無事にphp の再インストールが完了。

==> 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-httpd option. See  brew options php71 for more details.

By 31st March 2018 we will deprecate and archive the PHP tap.
Some of the formulae will be migrated to homebrew-core.

For more details, see https://github.com/Homebrew/homebrew-php/issues/4721

To restart homebrew/php/php71 after an upgrade:
  brew services restart homebrew/php/php71

最近、Railsは触っているだけで新しいことやってないな。PHP関連が続いたので、そろそろRailsもやりたいと思いつつ、 しばらくはPHP三昧になりそうです。
