一个比较有意思的函数，可以实现计算任意时间区间内工作日的函数。
这样你就能很方便的计算你每年的工作日有多少了。
/**
* @param $start_date 开始日期
* @param $end_date 结束日期
* @param $weekend_days 一周休息天数
*
* @return array
*/
function getWeekendDays($start_date, $end_date, $weekend_days=1) {
$data = array();
$start_reduce = $end_add = 0;
$start_N = date('N',strtotime($start_date));
$end_N = date('N',strtotime($end_date));
// 进行单、双休判断，默认按单休计算
$weekend_days = intval($weekend_days);
switch ($weekend_days)
{
case 2:
in_array($end_N,array(6,7)) && $end_add = ($end_N == 7) ? 2 : 1;
$start_reduce = ($start_N == 7) ? 1 : 0;
break;
case 1:
default:
$end_add = ($end_N == 7) ? 1 : 0;
break;
}
$days = ((strtotime($end_date) - strtotime($start_date))/86400) + 1;
$data['total_days'] = $days;
$data['total_relax'] = floor(($days + $start_N - 1 - $end_N) / 7) * $weekend_days - $start_reduce + $end_add;
return $data;
}
echo "Two days per week\n";
var_dump( getWeekendDays("2022-01-01","2022-12-31",1));
