Setup PHP and Composer on OSX via Brew

setup.md

First install Brew on your MAC

• Setup Brew: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• brew update
• brew tap homebrew/dupes
• brew tap homebrew/php
• Install PHP 7.0.+ brew install php70
• Install mcrypt: brew install mcrypt php70-mcrypt
• Finally, install composer: brew install composer

Now if you run $ php -v, you will get PHP 5.5 or something. This is the default PHP version that is shipped with OSX and cannot be removed. You just need to edit your path to ensure that PHP 7.0 is picked up.

export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH"

To debug any issue with any package, you can run brew info php70 etc.

Also, if you are getting seemingly unrelated errors, make sure to update bash/zsh: brew upgrade bash and brew upgrade zsh.

If everything is setup correctly, running $ php -v should give you 7.0.+.

PHP is moved to homebrew/core ,
brew tap homebrew/php gives this error
Error: homebrew/php was deprecated. This tap is now empty as all its formulae were migrated.

instead do brew tap homebrew/core

@deepkamal, You can use brew install php@7.0.

php is updated
to install php7.2
brew install php@7.2

For those unable to get mcrypt to install, try this:

brew install mcrypt php@7.2

brew install mcrypt php@7.2
brew services start php@7.2
brew link php@7.2 --force
php -v --> should give you 7.2 now on terminal if not, close session of term and open a new one (Restart)
brew install mcrypt php@7.2
brew install composer

Error: homebrew/php was deprecated. This tap is now empty as all its formulae were migrated.
