==> 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@7.1/7.1.29: 513 files, 63MB
==> Caveats
==> libidn
Emacs Lisp files have been installed to:
  /usr/local/share/emacs/site-lisp/libidn
==> openldap
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

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

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

==> curl-openssl
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

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

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/curl-openssl/lib
    CPPFLAGS: -I/usr/local/opt/curl-openssl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/curl-openssl/lib/pkgconfig

==> libtool
In order to prevent conflicts with Apple's own libtool we have prepended a "g"
so, you have instead: glibtool and glibtoolize.
==> gettext
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD gettext library & some software gets confused if both are in the library path.

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

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

==> libffi
This formula is keg-only, which means it was not symlinked into /usr/local,
because some formulae require a newer version of libffi.

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/libffi/lib
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/libffi/lib/pkgconfig

==> sqlite
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.

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

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/sqlite/lib
    CPPFLAGS: -I/usr/local/opt/sqlite/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/sqlite/lib/pkgconfig

==> python
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

See: https://docs.brew.sh/Homebrew-and-Python
==> libpq
This formula is keg-only, which means it was not symlinked into /usr/local,
because conflicts with postgres formula.

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

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/libpq/lib
    CPPFLAGS: -I/usr/local/opt/libpq/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/libpq/lib/pkgconfig

==> php@7.1
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:
