I am writing an application to do annual reviews. I cannot get my script to work. Whenever it runs I get the following error:
Code: $username='far'; $password='c00lfarus3r@'; $database='far';
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'www-data'@'localhost' (using password: NO) in /var/www/FARv2/scripts/insertsection1.php on line 18
Unable to select database.

This does not make sense to me. It has the username and password variables and does not seem to be using them. Who is user www-data? I am pretty new to php so I don't know where to start.
Here are all of the files:
