Php alongside Liferay and Tomcat

To get PHP to run alongside Liferay and Tomcat is a simple matter of modifying the liferay.conf file. Here's how you do it:
ssh into the server.
 cd /var/www/
 sudo mkdir directory name
sudo nano (or vim if you prefer) index.php
 Enter this into the text editor.
 <?php        echo "Hello World!";?> cd /etc/apache2/sites-enabled/
 sudo nano (or vim if that's your preference) 000-default
 Make sure the first item on the page looks like this...
 NameVirtualHost *:80 Make sure the <VirtualHost> directive looks like this...
 <VirtualHost *:80> Save and exit the file.
 sudo nano liferay.conf
 Make sure the <VirtualHosts> directive looks like this...
 <VirtualHost *:80> Add an alias inside the <VirtualHost> tag.
 Alias /apps "/var/www/apps" Add a <Directory> directive inside the <VirtualHost> tag. It should look like this...
 <Directory "/apps/">      Options FollowSymLinks      AllowOverride None      Order allow,deny      Allow from all      ProxyPass [http://localhost:80/apps/]
</Directory> Save and exit the file.
 Restart the server
 /etc/init.d/apache2 restart Test to see if it's working by navigating to the root URL of the server. You should be taken to Liferay. Then navigate to the siteurl/apps/ and you should see a blank page that says "Hello World".
