Make sure the directories /usr/local, /usr/local/bin and /usr/local/sbin exist and check the permissions, so that regular users can access them. This should already be the case, if you got Homebrew installed and working.
Open ~/.bash_profile and check, if /usr/local/bin and /usr/local/sbin are properly added to your PATH environment variable:
If there is no ~/.bash_profile yet, simply create it (see Mac OS X configuration for software developers).
Since using Homebrew seems overly complicated and you’ll get an outdated version (5.6.9 instead of 5.6.14 as of writing this), I recommend installing the binary package provided by Liip – thank you!
These commands will install the latest release of PHP 5.6 to /usr/local/php5:
