来源: 互联网 发布时间:2014-08-26
本文导语: 一、函数实现实例1: 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 $the_time; }else{ if...
一、函数实现
实例1:
代码如下:
function time_tran($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 $the_time;
}
}
}
实例2:
代码如下:
实例3:
代码如下:
function formatTime($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 $free."秒前";
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}else{
return '刚刚';
}
}
}
实例4:
代码如下:
function time_tran($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
代码如下:
