Ubuntu: PHP mCrypt Installation

mCrypt is an encryption program used on Linux systems.

To install mCrypt for PHP5 on your Ubuntu Linux system:

sudo apt-get install php5-mcrypt

Then restart Apache with:

sudo /etc/init.d/apache2 restart

I needed to do this so that  phpMyAdmin would have mcrypt available.
