Answer 1

判断是不是本星期。// 2008-12-25
$date1 = mktime('0','0','0','12','25','2008');
// 2008-12-5
$date2 = mktime('0','0','0','12','5','2008');
// 2008-12-7
$date3 = mktime('0','0','0','12','7','2008');var_dump(isCurrentWeek($date1));
var_dump(isCurrentWeek($date2));
var_dump(isCurrentWeek($date3));function isCurrentWeek($targetDate){
if(date("Y", $targetDate) == date("Y") 
&& date("W", $targetDate) == date("W")){
return true;
}
return false;
}

Answer 3

只需一行$date = "2008-12-08";
if (isCurrentWeeks($date)) {
echo $date."是本星期";
} else {
echo $date."不是本星期";
}function isCurrentWeeks($d) {
return (date("W",strtotime($d))==date("W",strtotime("now")));
}

看了楼上的...忘了考虑年份...改了一下$date = "2008-12-08";
if (isCurrentWeeks($date)) {
echo $date."是本星期";
} else {
echo $date."不是本星期";
}function isCurrentWeeks($d) {
return (date("Y-W",strtotime($d))==date("Y-W",strtotime("now")));
}
