php strtotime

在php中我想要获取时间戳有多种方法,最常用的就是使用time函数与strtotime()函数把日期转换成时间戳了,下面我来给大家分享一下时间戳函数 strtotime用法。
获取指定的年月日转化为时间戳:
pHP时间戳函数获取指定日期的unix时间戳 strtotime('2012-12-7')
示例如下:
复制代码 代码如下:


说明:返回2012年12月7日0点0分0秒时间戳。
 将当前年月日转化为时间戳:PHP时间戳函数获取当前日期的unix时间戳,
示例如下:
复制代码 代码如下:


明:返回当前时间 年月日时分秒的时间戳。
将时间戳转化为年月日:
复制代码 代码如下:
    echo date("Y-m-d H:i:s",intval(time()));
?>


复制代码 代码如下:
/*
from:http://www.bitsCN.com
@date:2013-02-22
*/
echo strtotime ("now"), "n";
echo strtotime ("10 September 2000"), "n";
echo strtotime ("+1 day"), "n";
echo strtotime ("+1 week"), "n";
echo strtotime ("+1 week 2 days 4 hours 2 seconds"), "n";
echo strtotime ("next Thursday"), "n";
echo strtotime ("last Monday"), "n";
?>

PHP时间戳函数获取英文文本日期时间
便于比较,使用date将当时间戳与指定时间戳转换成系统时间
(1)打印明天此时的时间戳strtotime(”+1 day”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间:echo date(”Y-m-d H:i:s”,strtotime(”+1 day”)) 结果:2009-01-23 09:40:25
(2)打印昨天此时的时间戳strtotime(”-1 day”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间: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”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间:echo date(”Y-m-d H:i:s”,strtotime(”+1 week”)) 结果:2009-01-29 09:40:25
(4)打印上个星期此时的时间戳strtotime(”-1 week”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间:echo date(”Y-m-d H:i:s”,strtotime(”-1 week”)) 结果:2009-01-15 09:40:25
(5)打印指定下星期几的时间戳strtotime(”next Thursday”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间:echo date(”Y-m-d H:i:s”,strtotime(”next Thursday”)) 结果:2009-01-29 00:00:00
(6)打印指定上星期几的时间戳strtotime(”last Thursday”)
当前时间:echo date(”Y-m-d H:i:s”,time()) 结果:2009-01-22 09:40:25
指定时间:echo date(”Y-m-d H:i:s”,strtotime(”last Thursday”)) 结果:2009-01-15 00:00:00
以上PHP时间戳函数示例可知源码天空,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。
