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
