==> Caveats
To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/php@7.1/lib/httpd/modules/libphp7.so

    <FilesMatch .php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.1/

This formula is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/php@7.1/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/php@7.1/sbin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/php@7.1/lib
    CPPFLAGS: -I/usr/local/opt/php@7.1/include


To have launchd start php@7.1 now and restart at login:
  brew services start php@7.1
Or, if you don't want/need a background service you can just run:
  php-fpm
==> Summary
🍺  /usr/local/Cellar/php@7.1/7.1.16_1: 514 files, 67MB

Path通す

.bash_profileに追加。

export PATH="/usr/local/opt/php@7.1/bin:$PATH"
export PATH="/usr/local/opt/php@7.1/sbin:$PATH"
