I need a script that, chosen random (userID), who are voting for at least 15 times a week.

If there is more than one, script randomly selects a winner (preference to those who have never won).

In this example, according to the winner should show every Monday.

The week starts on Monday at 00:00:00 and ends on Sunday at 23:59:59.

Server: Linux, Apache 2, PHP 5, MySQL 5

table 'ExampleTable'

$StartTime = '2010-11-01'; // Voting begins

$EndTime = '2010-12-05'; // Voting ends

$MinRecord = '15'; // minimal records in the last seven days (week) of the table "ExampleTable"

$MaxWin = '1'; // max winner of the week.


table 'Votings'

VoteID (INT)
GalleryID (INT)
PictureID (INT)
UserID (INT)
Voting (TINYINT)
VoteTime (DATETIME)

table 'winners'

winID
galleryID
