/**

 To do a basic log:

 new logger("MySQL_Username", "MySQL_Password", "MySQL_Database", "MySQL_Server");

 To check data after logging:
 $log = new logger("MySQL_Username", "MySQL_Password", "MySQL_Database", "MySQL_Server");
 echo $log->data['ip']; (Or whatever type of data you want to show.)

Constructive criticism is welcome via PM.
This class is still in development, a paginated output is on the way (so you can get your results out the DB and display them.)

Any suggestions for extending this code are welcome in the topic.

Any other comments, please do post in this topic.

Written in the hope it will be helpful, but no guarantee at all.
