==> Upgrading 1 outdated package:
php@7.2 7.2.16 -> 7.2.20
==> Upgrading php@7.2 
==> Installing dependencies for php@7.2: apr, argon2, libssh2, jemalloc, libev, nghttp2, curl-openssl, freetds, libpq and libsodium
==> Installing php@7.2 dependency: apr
==> Downloading https://homebrew.bintray.com/bottles/apr-1.7.0.mojave.bottle.tar.gz

==> Pouring apr-1.7.0.mojave.bottle.tar.gz
==> Caveats
apr is keg-only, which means it was not symlinked into /usr/local,
because Apple's CLT package contains apr.

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

After everything is finished, execute php to view the version:

$ php -v
