PHP中strtotime函数用法
strtotime函数在php中是可以把日志转换成时间戳,他可以方便的让我们对日期时间分秒的计算,下面我来给各位介绍时strtotime函数用法,有需要的同学可参考。
1.获取当前的时间的时间戳!
a.实用strtotime('now');来获取当前的时间戳!(因为PHP当前时间和真是时间相差8小时)
代码如下 | 复制代码 |
1 echo date('Y-m-d H:i:s',strtotime('now')+8*60*60); |
b.你也可以用time() 来直接获取!
代码如下 | 复制代码 |
|
2.获取10天之后的时间戳:
使用方法:
代码如下 | 复制代码 |
1 strtotime("+10 days")+8*60*60 |
输出10天后的日期,便于查看。
代码如下 | 复制代码 |
1 echo date('Y-m-d H:i:s',strtotime("+10 days")+8*60*60); |
结果:2013-04-15 03:15:02
3.获取一周的时间戳:
使用方法:
代码如下 | 复制代码 |
1 strtotime("+1 week")+8*60*60 |
或者你使用上面按天来获取时间戳.写法如:
代码如下 | 复制代码 |
strtotime("+7 days"); |
4.还可以获取指定几周几天几小时几秒来获取时间戳
使用方法:
代码如下 | 复制代码 |
1 strtotime ("+1 week 2 days 4 hours 2 seconds")+8*60*60 |
结果:2013-04-12 07:15:04;
5.获取上周一或者下周四的时间戳:
使用方法:
a.获取上周一的时间戳:
代码如下 | 复制代码 |
1 strtotime ("last Monday")+8*60*60 |
结果:2013-04-01 08:00:00;
b.获取下周四的时间戳
代码如下 | 复制代码 |
1 strtotime ("next Thursday")+8*60*60 |
结果:2013-04-11 08:00:00;
strtotime函数比较两个时间的大小
strtotime()函数对两个固定的时间进行比较,如下:
1):定义两个固定的时间;
2):通过strtotime()函数将固定时间转换成时间戳;
3):对两个时间戳的值进行比较。
其实例代码如下:
代码如下 | 复制代码 |
$time="2012年11月23日15时50时20秒"; |
上面的代码运行结果如下:
时间:2012年11月23日15时50时20秒 早于时间:2013-01-14 09:09:09
它们相差的时间值是:-1358125749

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
