Installing mcrypt extension for PHP on OSX Mountain Lion

I tend to use Homebrew on Mac. It will install and configure all the stuff for you.

Then you should be able to install it with brew install mcrypt php53-mcrypt and it’ll Just Work ™.

You can replace the 53 with whatever version of PHP you’re using, such as php56-mcrypt or php70-mcrypt. If you’re not sure, use brew search php.

Do also remember that if you are using the built in Mac PHP it’s installed into /usr/bin you can see which php you are using with which php at the terminal and it’ll return the path.
