Initially, I found bitmasking to be a confusing concept and found no use for it. So I've whipped up this code snippet in case anyone else is confused:

<?php

    // The various details a vehicle can have
    $hasFourWheels = 1;
    $hasTwoWheels  = 2;
    $hasDoors      = 4;
    $hasRedColour  = 8;

@function headings($from:1, $to:6) {
    @if $from == $to {
        @return 'h#{$from}';
    } @else {
        @return 'h#{$from},' + headings($from+1, $to);
    }
}
