php自定义的格式化时间示例代码

php自定义的格式化时间示例代码

时间刚好是5分钟前,则对应的时间戳就会被格式化为5分钟前,自定义的格式化时间方法如下,感兴趣的朋友可以参考下

如:时间刚好是5分钟前,则对应的时间戳就会被格式化为5分钟前,不多说了,直接贴上代码:

代码如下:

/**

* 格式化时间

* @param integer $timestamp 时间戳

* @param string $format dt=日期时间 d=日期 t=时间 u=个性化 其他=自定义

* @param integer $timeoffset 时区值

* @param string $custom_format 自定义时间格式

* @return string
