Here are some notes on installing PHP 5.3.3 (the latest version at time of writing) with Homebrew, an awesome package manager for OS X.
-
If you haven’t done so already, install Hombrew. Check out the installation instructions over at the Hombrew wiki.
-
Grab the latest copy of my PHP brew and copy it into your Homebrew Formula directory.
curl -O http://github.com/ampt/homebrew/raw/php/Library/Formula/php.rb mv php.rb `brew --prefix`/Library/Formula
-
Run the brew install php command. The following will install PHP with Apache and MySQL support.
brew install php --with-apache --with-mysql
Once thats done you should be good to go.
Note: Depending on your setup you may want to add the following to your .bash_profile:
echo 'export PATH='`brew --prefix php`':$PATH' >> .bash_profile
This will ensure that BASH has the correct path to the PHP you just installed.
Bonus Points: xdebug
Install xdebug (there’s a brew for that) a great tool to help debug your PHP code:
brew install xdebug
