How To – Activate PHP in public_html for Ubuntu 10

On my box I have Ubuntu 10.10, Apache/2.2.16 (Ubuntu) and PHP 5.3.3-1. Everything worked fine except the PHP files from ~userdir. Instead to parse these files, the web server send them directly to the browser which open the “save as” window.

# <directory /home/*/public_html>
# php_admin_value engine Off
# </directory>
# </ifmodule>

There are tons of information about this pattern over the Internet so I let you google for it.

You can find a singleton implementation in Simple MVC framework example.
