Answer 1

Here's something I whipped up. I'm pretty sure this could be more easily accomplished if you were using HTML lists, I've assumed you can't use them.

$arr    = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14, 15, 16);
$max    = count($arr);
$cols   = 3;
$block  = ceil($max / $cols);
for ($i = 0; $i < $block ; $i++) {
    echo $arr[$i] . ' ';

    for ($j = 1; $j < $cols; $j++) {
        $nexKey = $i  + $block * $j;
        if (!isset($arr[$nexKey])) break;   
        echo $arr[$nexKey] . ' ';
    }
    echo '
';
}

NOTE : You can easily refactor the code inside the loop that uses $nexkey variable by making it into a loop itself so that it works for any number of columns. I've hardcoded it.

Uses loops now.
