(2)打印昨天此时的时间戳strtotime("-1 day")
当前时间:
1.echo date("Y-m-d H:i:s",time())

结果:2009-01-22 09:40:25
指定时间:
1.echo date("Y-m-d H:i:s",strtotime("-1 day"))

结果:2009-01-21 09:40:25
(3)打印下个星期此时的时间戳strtotime("+1 week")

(6)打印指定上星期几的时间戳strtotime("last Thursday")
当前时间:
1.echo date("Y-m-d H:i:s",time())

结果:2009-01-22 09:40:25
指定时间:
1.echo date("Y-m-d H:i:s",strtotime("last Thursday"))

以上示例可知,strtotime能将任何英文文本的日期时间描述解析为Unix时间戳,我们结合mktime()或date()格式化日期时间获取指定的时间戳,实现所需要的日期时间。
