Hello Yahav Boaz,
I like your improved version, especially the examples you placed with it (probably just to stop my critisizing ;-))) I just wondered...
The function is now called with the seperate element. With those you create a timestanp and from this timestamp you regenerate the year, month and day. Couldn`t you suffice with:
function WeekDates($y,$m,$d){
$Weekday=date(`w`,mktime(0,0,0,$m,$d,$y));
for($x=0; $x<=6; $x++){
$DateArray[$x] = date(`Y-m-d`,$m,$d-$Weekday+$x,$y));
}
return $DateArray;
}
Or, to maximise for speed:
function WeekDates($y,$m,$d){
$FirstDOW=$d-date(`w`,mktime(0,0,0,$m,$d,$y));
for($x=0; $x<=6; $x++){
$DateArray[$x] = date(`Y-m-d`,$m,$FirstDOW+$x,$y));
}
return $DateArray;
}
As I see from the supplied examples PHP is smart enough to understand that a date like 2003/01/-1 means 2002/12/31. Quite a relieve since your funtcion relied upon it. Now it only relies on the fact that the first day of the week on the server must be the same as the user/programmer wants it to be (do I sense another enhancement here ;-)))
Regards,
Fred
