php计算几分钟前、几小时前、几天前的几个函数、类分享
这篇文章主要介绍了php计算时间几分钟前、几小时前、几天前的几个函数、类分享,需要的朋友可以参考下
一、函数实现
实例1:
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 $the_time; } } }
实例2:
<?php function format_date($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:
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 $free."秒前"; }else{ return '刚刚'; } } }else{ return '刚刚'; } } }else{ return '刚刚'; } } }
实例4:
function time_tran($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
<?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); }
function getDay() { return ($this->createtime-$this->gettime)/(60*60*24); }
function getMonth() { return ($this->createtime-$this->gettime)/(60*60*24*30); }
function getYear() { return ($this->createtime-$this->gettime)/(60*60*24*30*12); }
function index() { if($this->getYear() > 1) { if($this->getYear() > 2) { return date("Y-m-d",$this->gettime); exit(); } return intval($this->getYear())." 年前"; exit(); }
if($this->getMonth() > 1) { return intval($this->getMonth())." 月前"; exit(); }
if($this->getDay() > 1) { return intval($this->getDay())." 天前"; exit(); }
if($this->getHours() > 1) { return intval($this->getHours())." 小时前"; exit(); }
if($this->getMinutes() > 1) { return intval($this->getMinutes())." 分钟前"; exit(); }
if($this->getSeconds() > 1) { return intval($this->getSeconds()-1)." 秒前"; exit(); }
}
} //类的使用实例 /* * * 调用类输出方式 * * $a = new Mygettime(time(),strtotime('-25 month')); * echo iconv('utf-8', 'gb2312', $a->index())?iconv('utf-8', 'gb2312', $a->index()):iconv('utf-8', 'gb2312', '当前'); * */
