First install Brew on your MAC
- Setup Brew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew tap homebrew/dupes
brew tap homebrew/php
- Install PHP 7.0.+
brew install php70
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.+.
