Hmm, this may require some java scripting as it would be very difficult to do in php. If you really need to use php you could try using date functions but to get a random 10 articles is demanding. Too much scripting for me to write at the moment but yes, it is possible and most probably someone on this forum would have some pre made scripts.~alzable

Well here's a shot at it, we might be able to tweak this toward your application.

<?php$startTime = mktime(0, 0, 0, 1, 1, date('Y'));$now = time();$week = 7 * 24 * 60 * 60;$wkNumber = ceil(($now - $startTime)/$week);$cycle = ($wkNumber % 5);$randNumber = 0;echo "This is week number $wkNumber.<br>";echo "We are working with cycle number $cycle.<br>";function mkRand($lwrLimit, $uprLimit){  global $randNumber;  $randNumber = mt_rand($lwrLimit, $uprLimit);}switch($cycle){  case 0:    mkRand(1, 10);    break;  case 1:    mkRand(11, 20);    break;  case 2:    mkRand(21, 30);    break;  case 3:    mkRand(31, 40);    break;  default:    mkRand(41, 50);    break;    }echo "The random number is $randNumber";    ?>

Did you want to display one unique out of a group of 10?-or-Did you want to display a group of 10 at the same time on the same page?Thanks,
