I currently have a list (
You can just loop twice, once for each column. Start at 0 in the first column and at 1 in the second. Increment by two.
Edit: To make it even nicer, put the columns themselves in a loop:
$cols = 3;
echo '';
// column loop
for ($c = 1; $c <= $cols; $c++) {
echo '';
// item loop
for ($i = 0; $i < count($areaArray); $i += $c) {
echo '- ...
';
}
echo '
';
}
echo '
';
