this builds an array of available article ids in $a
eg. a would end up with
a[0] = 34
a[1] = 35
a[2] = 36
. you could expand the logic here to include the conditions below on whether

this takes the array of available articles and builds an assoicative array of
articles to display in $b - based on a random number. and maxes out at 4 items
$b[34] = "USEME";
$b[32] = "USEME";
$b[33] = "USEME";

since there should only be 4 articles in $b (actually It may need a bit of
fine tuning as I think counting associate arrays is a bit flakey)

I would suggest playing with the code, try printing stuff as it goes along to
see what is happening, remember that $o is an object so you cant print $o, but
you can print $o->title, $o->id etc.
