1、UNIX时间戳转换为日期用函数: FROM_UNIXTIME()
[sql] view plain copy
- select FROM_UNIXTIME(1156219870);
输出:2006-08-22 12:11:10
2、日期转换为UNIX时间戳用函数: UNIX_TIMESTAMP()
[sql] view plain copy
- Select UNIX_TIMESTAMP(‘2006-11-04 12:23:00‘);
[sql] view plain copy
- 输出:1162614180
[sql] view plain copy
- Select UNIX_TIMESTAMP(NOW());
[sql] view plain copy
[sql] view plain copy
- 输出当前时间戳
例:mysql查询当天的记录数:
[sql] view plain copy
- $sql=”select * from message Where DATE_FORMAT(FROM_UNIXTIME(chattime),’%Y-%m-%d’) = DATE_FORMAT(NOW(),’%Y-%m-%d’) order by id desc”;
PHP方式转换:
UNIX时间戳转换为日期用函数: date()
date(‘Y-m-d H:i:s‘, 1156219870);
日期转换为UNIX时间戳用函数:strtotime()
strtotime(‘2010-03-24 08:15:42‘);
