PHP时间类完整实例(非常实用)
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");
classtime{
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
functiongetyear($time="",$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
functiongetmonth($time="",$type=""){
if($time==""){
$time=time();
}
switch($type){
case1:$this->month=date("n",$time);//返回格式3
break;
case2:$this->month=date("m",$time);//返回格式03
break;
