<code>date('Y-m-d H:i:s',strtotime('+2 days')); </code>
换个思路嘛,
你管一个月多少天干嘛呢?直接用时间戳判断不就行了?
先日期+2
然后分别判断月份,注意2月和闰年
最近学python时写的代码,仅供参考
<code>c_day += 2 if ( c_day == 29 and c_month == 2 and not is_leap_year ) \ or ( c_day == 30 and c_month == 2 ) \ or ( c_day == 31 and (c_month == 4 or c_month == 6 or c_month == 9 or c_month == 11) ) \ or ( c_day == 32 and (c_month == 1 or c_month == 3 or c_month == 5 or c_month == 7 or c_month == 8 or c_month == 10) ) \ or ( c_day == 32 and c_month == 12 ): if c_day == 32 and c_month == 12: #when 12 year should increase c_year += 1 c_month = 1 is_leap_year = (c_year%400 == 0 or (c_year%4 == 0 and c_year%100 )) else: c_month += 1 c_day = 1 </code>

<code>$dateTime = new DateTime("now",new DateTimeZone("Asia/Chongqing")); $dateTime->modify("+2 day"); echo $dateTime->format("Y-m-d"); </code>
