Wraps `phpbrew switch xx` in a shell script to facilitate automatic php switching in apache as well as the standard cli

switchphp.sh

#!/bin/bash
# wraps phpbrew switch to enable apache switching
# Author: Matt Holbrook-Bull
# 
# requirements:
#         /etc/apache2/modules must be writable
#         you must have apxs2 extension compiled into your php installs
#         "chmod +x switchphp.sh" - to make executable
#
# usage:
#         ./switchphp.sh 5.6
#
# notes:
#         dont run with sudo, if you need to then /etc/apache2 isnt writable, or you installed phpbrew with sudo (which you shouldnt)
#         change the 'so' filenames to match the lib files in '/usr/lib/apache2/modules' as per your install
#	  youll need to restart apache after running
# fail commands gracefully
set -e
set -o pipefail
