RE: [PHP] easy date question?

[Martin Towell]

If you want to make it a few line shorter, change

         if ($MonthStartDay < $Day)
         {
                 $C = $Day - $MonthStartDay;
         }
         else if ($MonthStartDay > $Day)
         {
                 $C = 7 - $MonthStartDay + $Day;
         }

to

         $C = ($MonthStartDay > $Day ? 7 : 0) + $Day - $MonthStartDay;

or maybe

         $C = ($MonthStartDay < $Day ? 0 : 7) + $Day - $MonthStartDay;

I haven't tried either one, so it may break it...

If one, or both, work, then you could combine this line with the "return"
line

I came up with a solution that I'd like to share.  Could someone confirm 
whether it's the best approach?

Thanks,

--------- source code ----------------

# ex.: GetDay ("Third", "Saturday", 5, 2002);
function GetDay($Week, $Day, $Month, $Year)
{
         $MonthStartDay = date("w", mktime(0,0,0,$Month,1,$Year) ) + 1;

         switch ($Week)
         {
                 case "First" : $Week = 0; break;
                 case "Second" : $Week = 7; break;
                 case "Third" : $Week = 14; break;
                 case "Fourth" : $Week = 21; break;
         }

         switch ($Day)
         {
                 case "Sunday" : $Day = 1; break;
                 case "Monday" : $Day = 2; break;
                 case "Tuesday" : $Day = 3; break;
                 case "Wednesday" : $Day = 4; break;
                 case "Thursday" : $Day = 5; break;
                 case "Friday" : $Day = 6; break;
                 case "Saturday" : $Day = 7; break;
         }

         $C = 0;

         if ($MonthStartDay < $Day)
         {
                 $C = $Day - $MonthStartDay;
         }
         else if ($MonthStartDay > $Day)
         {
                 $C = 7 - $MonthStartDay + $Day;
         }

         return ($C + 1 + $Week);
}
