php时间戳strtotime前一天或后一天的日期
直接上代码,自己去运行吧。
date_default_timezone_set('PRC'); //默认时区
//指定的时间增加5天
$date1 = "2014-11-11";
echo date('Y-m-d', strtotime("$date1 +5 day")) . "
";//输出结果:2014-11-16
//当前的时间增加5天(今天是 2016-06-25)
echo date('Y-m-d', strtotime("+5 day")) . "
";//输出结果:2016-06-30
//相应地,要增加月,年,将day改成month或year即可
//+++ 今天、昨天、明天 、上一周、下一周 +++++++++
echo "今天:" . date("Y-m-d", time()) . "
";
echo "昨天:" . date("Y-m-d", strtotime("-1 day")) . "
";
echo "明天:" . date("Y-m-d", strtotime("+1 day")) . "
";
echo "一周后:" . date("Y-m-d", strtotime("+1 week")) . "

echo "一周零两天四小时两秒后:" . date("Y-m-d G:H:s", strtotime("+1 week 2 days 4 hours 2 seconds")) . "
";
echo "下个星期四:" . date("Y-m-d", strtotime("next Thursday")) . "
