This is an example of what one may call straight coding - just plain features used.

<?php

class Dayofweek {
# constant init values okay
private $a = array('Mon', 'Tues', 'Wed', 'Thurs', 'Friday','Sat', 'Sun');
function getDow($n) {
if ($this->isInbounds($n)) {
return $this->a[$n];
} else {
trigger_error('Dayofweek index out of range', E_USER_ERROR);
}
}
function isInbounds($n) {
return (-1 < $n && $n < count($this->a));
}
function getDow1based($n) {
return $this->getDow($n-1);
}
function getDowTolerant($n) {
if ($this->isInbounds($n)) return $this->a[$n];
else return "";
}
}
