The last day of any given month can be expressed as the "0" day
of the next month, not the -1 day. Both of the following examples
will produce the string "The last day in Feb 2000 is: 29".
<example>
<programlisting>
$lastday=mktime(0,0,0,3,0,2000);
echo strftime("Last day in Feb 2000 is: %d",$lastday);
$lastday=mktime(0,0,0,4,-31,2000);
echo strftime("Last day in Feb 2000 is: %d",$lastday);
