Question

我一直试图找到一种方法来可靠地获取过去三个工作日的时间戳，无论输入日期和困难。我非常感谢任何建议。

这就是我的尝试：

    $date = date() - 60*60*24*3; 
    $timestamps = array();
    for($i=0; $i < 3; $i++){
       $timestamps[] = strtotime($date  . ' ' . $i . ' weekdays');
    }

我正在寻找以下内容：

Input: lastThreeBusinessDays(date()); //Friday August 1 2014
Output (Array with timestamps for the following dates): 
Thursday July 31 2014, Wednesday July 30 2014, Tuesday July 29 2014 

Input: lastThreeBusinessDays(date()); //Saturday August 2 2014
Output (Array with timestamps for the following dates): 
Friday August 1, Thursday July 31 2014, Wednesday July 30 2014

Input: lastThreeBusinessDays(date()); //Sunday August 3 2014
Output (Array with timestamps for the following dates):
Friday August 1, Thursday July 31 2014, Wednesday July 30 2014

非常感谢提前！

时间戳具有秒粒度，因此获取一天的时间戳非常模糊。以下代码（假设工作日表示每天，但周六和周日）执行要求：

$timestamp = time();

$timestamps = array();
for ($n = 0; $n < 3; ++$n) {
    // The following cycle skips saturdays and sundays
    do {
        $timestamp -= 60*60*24;
    } while (date('N', $timestamp) > 5);
    $timestamps[] = $timestamp;
}

最近三个工作日的时间戳
