環境

PHP7.3インストール

現状確認

$ php -v
PHP 7.1.23 (cli) (built: Feb 22 2019 22:19:32) ( NTS )

$ brew search php@7
==> Formulae
php@7.1 php@7.2 php@7.3

インストール

brew install php@7.3

後処理

インストール時にパスを通してね、環境変数入れてね、みたいなワーニングが出ます。
以下、一例

If you need to have libpq first in your PATH run:
  echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.bash_profile

For compilers to find libpq you may need to set:
  export LDFLAGS="-L/usr/local/opt/libpq/lib"
  export CPPFLAGS="-I/usr/local/opt/libpq/include"

For pkg-config to find libpq you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/libpq/lib/pkgconfig"

その指定に従って以下を実行。

$ echo 'export PATH="/usr/local/opt/apr/bin:$PATH"' >> ~/.bash_profile
$ vim ~/.bash_profile
$ echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.bash_profile
$ export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
$ export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
$ echo 'export PATH="/usr/local/opt/apr-util/bin:$PATH"' >> ~/.bash_profile
$ echo 'export PATH="/usr/local/opt/openldap/bin:$PATH"' >> ~/.bash_profile
$ echo 'export PATH="/usr/local/opt/openldap/sbin:$PATH"' >> ~/.bash_profile
$ echo 'export PATH="/usr/local/opt/curl-openssl/bin:$PATH"' >> ~/.bash_profile
$ export PKG_CONFIG_PATH="/usr/local/opt/curl-openssl/lib/pkgconfig"
$ echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.bash_profile
$ export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"
$ echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.bash_profile
$ export PKG_CONFIG_PATH="/usr/local/opt/sqlite/lib/pkgconfig"
$ echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.bash_profile
$ export PKG_CONFIG_PATH="/usr/local/opt/libpq/lib/pkgconfig"
$ brew services start php

結果

あれ！！バージョン変わってない！！
