nb. Notice the log must now be read twice!
Copy the code into a file called index.php and drop it into a directory accessible to your web server and ensure you grant the file execution rights.
Alter the $filepath = "/opt/minecraft/server.log"; line so that it points to your server log and ensure the web server has read rights to this file.
Just open the PHP code in your browser and the a page should open showing today's log entries, scrolled to the bottom of the log.
If you then select an earlier date the page will refresh and show this dates entries without the auto-scrolling.
