Sounds like an A level maths question :)
One way of doing it - off the top of my head
1. build an an array of the available articles
$o = mgd_list_topic_articles(x)
$a = array();
while ($o->fetch()) $a[]= $o->id;
2. build a list of articles from that list (using random numbers?)
function randomint($max = 100) {
static $startseed = 0;
if (!$startseed) {
$startseed = (double)microtime()*getrandmax();
srand($startseed);
}
return (rand()%$max);
}
$b=array()
while (count($b)<4) {
$n = randomint(count($a));
if (!$b[$a[$n]]) $b[$a[$n]] = "USEME";
}
3. print them
while (list($k,v) = each($b)) {
mgd_get_article($k)
// print it!
}
Off the top of my head (and late at night).... - I'm sure theres other ways to
do it :)
