Email Open Tracking in PHP

This code shows how to use HTML emails and PHP/MySQL to track email opens and clickthroughs

It is intended as a complement to my tutorial: http://tonygaitatzis.tumblr.com/post/65647388814/big-data-email-open-tracking-in-php

Configuration

Set up your settings file to reflect your MySQL server settings.

$settings['mysql']['server'] = 'localhost';
$settings['mysql']['username'] = 'mysqluser';
$settings['mysql']['password'] = 'mysqlpassword';
$settings['mysql']['schema'] = 'tracker_example';

Now You should be good to go.
