一、函数实现
实例1:
复制代码 代码如下:
function time_tran($the_time){
$now_time = date("Y-m-d H:i:s",time()+8*60*60);
$now_time = strtotime($now_time);
$show_time = strtotime($the_time);
$dur = $now_time - $show_time;
if($dur < 0){
return $the_time;
}else{
if($dur < 60){
return $dur.'秒前';
}else{
if($dur < 3600){
return floor($dur/60).'分钟前';
}else{
if($dur < 86400){
return floor($dur/3600).'小时前';
}else{
if($dur < 259200){//3天内
return floor($dur/86400).'天前';
}else{
return $the_time;
}
}
}
实例2:
复制代码 代码如下:
<?php
function format_date($time){
$t=time()-$time;
$f=array(
'31536000'=>'年',
'2592000'=>'个月',
'604800'=>'星期',
'86400'=>'天',
'3600'=>'小时',
'60'=>'分钟',
'1'=>'秒'
);
foreach ($f as $k=>$v) {
if (0 !=$c=floor($t/(int)$k)) {
return $c.$v.'前';
}
}
}
?>
实例3:
复制代码 代码如下:
function formatTime($date) {
$str = '';
$timer = strtotime($date);
$diff = $_SERVER['REQUEST_TIME'] - $timer;
$day = floor($diff / 86400);
$free = $diff % 86400;
if($day > 0) {
return $day."天前";
}else{
if($free>0){
$hour = floor($free / 3600);
$free = $free % 3600;
if($hour>0){
return $hour."小时前";
}else{
if($free>0){
$min = floor($free / 60);
$free = $free % 60;
if($min>0){
return $min."分钟前";
}else{
if($free>0){
return $free."秒前";
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}
实例4:
复制代码 代码如下:
function time_tran($the_time){
$now_time = date("Y-m-d H:i:s",time()+8*60*60);
$now_time = strtotime($now_time);
$show_time = strtotime($the_time);
$dur = $now_time - $show_time;
if($dur < 0){
return $the_time;
}else{
if($dur < 60){
return $dur.'秒前';
}else{
if($dur < 3600){
return floor($dur/60).'分钟前';
}else{
if($dur < 86400){
return floor($dur/3600).'小时前';
}else{
if($dur < 259200){//3天内
return floor($dur/86400).'天前';
}else{
return $the_time;
}
}
}
}
}
}
二、类的实现
复制代码 代码如下:
<?php
/*
* author: Solon Ring
* time: 2011-11-02
* 发博时间计算(年,月,日,时,分,秒)
* $createtime 可以是当前时间
* $gettime 你要传进来的时间
*/
class Mygettime{
function __construct($createtime,$gettime) {
$this->createtime = $createtime;
$this->gettime = $gettime;
}
function getSeconds()
{
return $this->createtime-$this->gettime;
}
function getMinutes()
{
return ($this->createtime-$this->gettime)/(60);
}
function getHours()
{
return ($this->createtime-$this->gettime)/(60*60);
}
