You can get the day of week using the same function you used to get the day, month, and year: http://www.php.net/manual/en/function.date.php

You only get one date because you're only storing one date. If you want all 15 dates, then you need to store your dates in an array. Your while loop on your mysql_fetch_array stores its results into the same variable each time, thus overwriting the previous row's results.

Using a linked list is killing you, I think. Have you tried a tree or hash structure? A hash will be faster at a larger (probably much larger) memory footprint, but a tree should be only a slightly larger footprint to a linked list but faster for sorting. Probably something like a red-black tree should work much better for you.

What browser(s) are you testing in?
