i want to create a page, which loops on itself, eg page.php

the page sources from a very large database, so i want to display 20 entrys per page, and display them in order of points, then alphabetically.  i dont want to display enrtys multiple time.

i havent written any PHP, but im thinking of how to approach this problem.

All help  is much appreciated,

Now I think that most of this can be solved with your approach towards searching the data base. To display results by a specific order you can use something like this:

[code=php:0]$query = "SELECT search1, search2 FROM your_table ORDER BY your_order limit 0, 20";[/code]

I wrote this quickly so you might want to search the manual for the proper syntax. Hopefully this will help alittle.
ok. then how would i display enrties 20 - 40

and there fore would i have to create a script that would re-rank the entrys.  (im writing a game, so the database is continually minipulated)

if so, how would i write it so that it runns every, 20 minute (or like), without me having to continually manually run the script.  i want the site to be as sent maintaing as possible

thanks for your help with that query,

There you go good luck.
