apache 2.2 - Multiple php versions simultaneously on Ubuntu

I want to be able to run multiple php versions on my
development box running Ubuntu 12.04. What I want to accomplish is that when I use
localhost as domain a default is used (let's say php 5.3.17). When I use 547.localhost
as domain php 5.4.7 is used. I've seen some tutorials to get this working using fastcgi
but until now I haven't been able to get it to work.
I've looked at these
tutorials:

For
as far as I can see I have done everything that is needed. The problem is that php
simply doesn't run. When I go to
http://localhost/somephpfile.php it just outputs the source of
the php file. The same for
http://547.localhost/somephpfile.php.

I'll break down what steps I took in
the hope that someone is able to spot what I
missed.

1. First I installed
   a default lamp stack using sudo apt-get install lamp-server^
phpmyadmin. After this I had a working development server running the
   repository version of php.


2. Then I used phpfarm to create
   two php installs, one for 5.3.17 and one for 5.4.7. The localion of phpfarm is
   /etc/php/phpfarm, so the executables are in
   /etc/php/phpfarm/inst/php-{version}/bin


3. Then
   I enable suaxec and fastcgi for apache and disabe mod_php with sudo a2enmod
fastcgi actions suexec && sudo a2dismod
php5



4. Next, I edited
   /etc/apache2/mods-enabled/fastcgi.conf to read:
   

   
   
   

   
               
   
    FastCgiIpcDir /var/lib/apache2/fastcgi 
    FastCgiWrapper
               /usr/lib/apache2/suexec FastCgiConfig -idle-timeout
    110 -killInterval 120
               -pass-header HTTP_AUTHORIZATION -autoUpdate 
    ScriptAlias /php-fcgi/
               /var/www/cgi-bin/
               
   
   




5. Then
   in /var/www/ I created a folder cgi-bin and in this folder two
   files, for each of the two php versions as follows (I show only the one for 5.3.17
   /var/www/php5317.fcgi):

   
   
   

   #!/bin/sh
   #
               you can change the PHP version here.
   
   version="5.3.17"
   #
               php.ini file location, */php-5.2.13/lib equals
               */php-5.2.13/lib/php.ini.
   PHPRC=/etc/php/phpfarm/inst/php-${version}/lib/php.ini
   export
               PHPRC
   
   PHP_FCGI_CHILDREN=3
   export
               PHP_FCGI_CHILDREN
   
   PHP_FCGI_MAX_REQUESTS=5000
   export
               PHP_FCGI_MAX_REQUESTS
   
   
   # which php-cgi binary to
               execute
   exec
               /etc/php/phpfarm/inst/php-${version}/bin/php-cgi
   




6. The
   last step was to create virtual hosts. In the end I have three files in
   /etc/apache2/sites-enabled: 000-default, php5.3.17 and php5.4.7
   With the following
   contents:

   
   
   

   default:

   
   
   

               *:80>
    ServerName localhost
   
    DocumentRoot
               /var/www
    
    Options Indexes
               FollowSymLinks MultiViews
    AllowOverride All
    Order
               allow,deny
    allow from all
    AddHandler php-cgi .php
   
               Action php-cgi /php-fcgi/php5317.fcgi
   
               
   
   
   

   
   
   

   php5.3.17:

   
   
   

               *:80>
    ServerName 5317.localhost
    DocumentRoot
               /var/www
    
    Options Indexes
               FollowSymLinks MultiViews
    AllowOverride All
   
    Order
               allow,deny
    allow from all
    AddHandler php-cgi .php
   
               Action php-cgi /php-fcgi/php5317.fcgi
   
               
   
   

   
   
   

   php5.4.7:

   
   
   
   

               *:80>
    ServerName 547.localhost
    DocumentRoot /var/www
   
               
    Options Indexes FollowSymLinks
               MultiViews
    AllowOverride All
    Order allow,deny
    allow
               from all
    AddHandler php-cgi .php
    Action php-cgi
               /php-fcgi/php547.fcgi
   
   
               
   
   




7. Finally
   I changed /etc/hosts to
   read

   
   
   

   127.0.0.1
               localhost
   127.0.0.1 547.localhost
   127.0.0.1
               5317.localhost
   
   # The following lines are desirable for IPv6 capable
               hosts
   
   ::1 ip6-localhost ip6-loopback
   fe00::0
               ip6-localnet
   ff00::0 ip6-mcastprefix
   ff02::1
               ip6-allnodes
   ff02::2
               ip6-allrouters
   

Now
I would expect things to work, but sadly they don't. Instead that a php files runs
through php it just outputs the raw
file.

There must be something I
missed here, but I have gone through the process many times and I can't figure out where
it goes wrong.
