# Setphp helps out in running Apache with either php4 or php5 and makes
# switching between these versions easy.

#
# DESCRIPTION:
# Before using this script, please follow these instructions.
#
# [ 0 ] make sure you have downloaded the php4 and php5
# packages found at: http://www.entropy.ch/software/macosx/php/
#
# [ 1 ] install PHP 4 and configure the httpd.conf file to your liking.
# Once that is done, save a copy of the file as php4.httpd.conf in /etc/httpd/
#
# [ 2 ] install PHP 5 and configure the new httpd.conf file to suit your PHP 5 work.
# Once that is done, save a copy of the file as php5.httpd.conf in /etc/httpd/.
#   
# [ 3 ] create a file called phpinfo.php and copy these contents into it:
#   <?php phpinfo(); ?>
#
# [ 4 ] copy the above created file into your webdirectory
#   Usually: /Users/username/Sites/ (where username is your username)
#
# [ 5 ] copy this script anywhere in your PATH. A good place would be:
#    /usr/local/bin/
#
# [ 6 ] make sure the script is executable, i.e. chmod ug+x setphp
#
# [ 7 ] each time you would like to switch from php version just open an terminal
# and type: setphp phpX (where phpX is php4 or php5)
#
# [ 8 ] check if the script worked as expected by going to 127.0.0.1/phpinfo.php
# this would give you the specific php4 or php5 version   
#
# This script was made in the hope it would make my life easier, feel free to
# use and abuse it as you see fit. However WITHOUT ANY WARRANTY. So if this
# script causes your computer to tell bad jokes, its not my problem.
