从PHP中获取日期中月份的周数？

我认为这种关系应该是正确的并且派上用场：

Week of the month = Week of the year - Week of the year of first day of month + 1

在PHP中实现，您将获得以下信息：

function weekOfMonth($date) {    //Get the first day of the month.    $firstOfMonth = strtotime(date("Y-m-01", $date));    //Apply above formula.    return intval(date("W", $date)) - intval(date("W", $firstOfMonth)) + 1;}

要获得从星期日开始的几周，只需将都替换

date("W", ...)

strftime("%U", ...)
