PHP时间类完整实例(非常实用)
这篇文章主要介绍了PHP时间类完整实例,涉及PHP针对日期、时间、星期等的获取与比较等操作技巧,非常简单实用,需要的朋友可以参考下,本文实例讲述了PHP时间类,分享给大家供大家参考,具体如下:
- <?php
- header("Content-type:text/html;Charset=utf-8");
- class time{
- private $year;//年
- private $month;//月
- private $day;//天
- private $hour;//小时
- private $minute;//分钟
- private $second;//秒
- private $microtime;//毫秒
- private $weekday;//星期
- private $longDate;//完整的时间格式
- private $diffTime;//两个时间的差值
- //返回年份 time:时间格式为时间戳 2013-3-27
- function getyear($time="",$type=""){
- if($time==""){
- $time=time();
- }
- if($type==1){
- return $this->year=date("y",$time); //返回两位的年份 13
- }else{
- return $this->year=date("Y",$time); //返回四位的年份 2013
- }
- }
- //返回当前时间的月份 time:时间格式为时间戳 2013-3-27
- function getmonth($time="",$type=""){
- if($time==""){
- $time=time();
- }
- switch($type){
- case 1:$this->month=date("n",$time);//返回格式 3
- break;
- case 2:$this->month=date("m",$time);//返回格式 03
- break;
- case 3:$this->month=date("M",$time);//返回格式 Mar
- break;
- case 4:$this->month=date("F",$time);//返回格式 March
- break;
- default:$this->month=date("n",$time);
- }
- return $this->month;
- }
- //返回当前时间的天数 time:时间格式为时间戳 2013-3-4

- //比较两个时间的大小 格式 2013-3-4 8:4:3
- function compare($time1,$time2){

- return 1;
- }else{

- //比较两个时间的差值
- function diffdate($time1="",$time2=""){
