找到的一個(gè)方案如下：
function get_weekend_days($start_date, $end_date, $weekend_days=1) {
$data = array();
$start_reduce = $end_add = 0;
$start_N = date('N',strtotime($start_date));
$start_reduce = ($start_N == 7) ? 1 : 0;
$end_N = date('N',strtotime($end_date));
// 進(jìn)行單、雙休判斷，默認(rèn)按單休計(jì)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;
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 $data;
}
這個(gè)$data['total_relax'] 為什么要這樣計(jì)算呢？ 這方法好像不太好用，比如今天 是周天 但是返回的$data['total_relax']是0

試試這個(gè)修改過(guò)的
<?php
