I've been meaning to post instructions on how to compile PHP for Snow Leopard since last summer when I picked up the DVD, but hadn't found the time or opportunity to build PHP from a completely fresh start, until a few weeks ago. This time, I took notes on how to reliably compile PHP and Apache from scratch on this system.

He's made a six step process that includes installing Xcode, Homebrew, your own version of iconv, support for whatever dependencies you might still need and, of course, Apache/PHP.
