计算一个月的工作天数 [英] Calculate number of working days in a month

问题描述

可能重复：

获取给定月份的工作日数

如何计算任何月份的工作日？ cal_days_in_month 只返回一个月内的总天数。我的任务是计算除星期六，星期日或星期日以外的月份天数。任何方法找到这个？

How to calculate working days of any month? cal_days_in_month returns simply the total number of days in a month. My task is to calculate number of days in month except Saturdays and Sundays or Sundays alone. Any method to find this?

推荐答案

function countDays($year, $month, $ignore) {
    $count = 0;
    $counter = mktime(0, 0, 0, $month, 1, $year);
    while (date("n", $counter) == $month) {
        if (in_array(date("w", $counter), $ignore) == false) {
            $count++;
        }
        $counter = strtotime("+1 day", $counter);
    }
    return $count;
}
echo countDays(2013, 1, array(0, 6)); // 23

date 函数。关于忽略参数的注意事项：0是星期日，...，6是星期六。

The date function is used in this example. Note about ignore parameter: 0 is sunday, ..., 6 is saturday.
