php7_install.sh

#!/bin/bash
# The easy version is `curl -s http://php-osx.liip.ch/install.sh | bash -s 7.0`
# It might be better to use (build-entropy-php)[https://github.com/liip/build-entropy-php] for building.

# Create the destinaiton folder.
mkdir -p /usr/local/builds/php

# Clone the php source (Just using the master branch).
git clone https://git.php.net/repository/php-src.git /usr/local/builds/php/7.x

# Install the right version of bison.
cd ../
git checkout adf87c6 /usr/local/Library/Formula/bison.rb
# I had an error first time I tried to install bison. This fixed it.
