关于php自定义的格式化时间

这篇文章主要介绍了关于php自定义的格式化时间，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下

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： 

/** 
* 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
