Well, you don't need to know what row number is. Something like:
function build_folder_tree(&$output, $parent=1, $indent="")
{
$color = "red"; // Set var to first option
$qid = mysql_query("SELECT id, name FROM folders WHERE parent_id =
$parent");
while ($cat = mysql_fetch_object($qid))
{
$output .= $cat->name + $indent; // here is where I want to assign
diff. colors
$color == "red" ? $color = "blue": $color = "red"; // Cycle color for
each iteration
if ($cat->id != $parent)
build_folder_tree($output, $cat->id, $indent." ");
}
}
