Answer 2

After update brew:

brew update
brew upgrade
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php

If you have installed php5.6 (or higher), you can use the following command to find out what versions are available in brew:

$ brew search mcrypt
homebrew/php/php53-mcrypt     homebrew/php/php55-mcrypt         homebrew/php/php70-mcrypt     mcrypt
homebrew/php/php54-mcrypt     homebrew/php/php56-mcrypt     homebrew/php/php71-mcrypt

In my case, I am using php7.0:

$ brew install php70-mcrypt
