PHP calculates several functions and classes shared minutes ago, hours ago, and days ago_PHP Tutorial

1. Function implementation
Example 1:

Copy code The code is as follows:

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 $dur.'seconds ago';
}else{
if($dur < 3600){
return floor($dur/60).'minutes ago';
}else{
}else{
 if($dur < 86400){
  return floor($dur/3600).'hours ago';
}else{
 if($dur < 259200){//Within 3 days
          return floor($dur/86400).'days ago'; 🎜>

Example 2:

Copy code

The code is as follows:

function format_date( $time){ $t=time()-$time; $f=array(

'31536000'=>'year',

'2592000'=>'month ',
'604800'=>'week',
'86400'=>'day',
'3600'=>'hour',
'60'=> 'Minutes',
'1'=>'Seconds'
);
foreach ($f as $k=>$v) {
if (0 !=$c=floor ($ t/(int) $ k)) {
Return $ C. $ v.
Example 3:



Copy code

The code is as follows:

function formatTime($date) {$str = '';

$timer = strtotime($date);
$diff = $_SERVER['REQUEST_TIME'] - $timer;

$day = floor($diff / 86400); $free = $diff % 86400;if($day > 0) {return $day."days ago";}else{

if($free>0){

$hour = floor($free / 3600);
$free = $free % 3600;
if($hour>0){
return $hour."hour ago";
}else{
if($free>0){
$min = floor($free / 60);
$free = $free % 60;
if($min>0){
return $min."minutes ago";
}else{
if($free>0){
return $free."seconds ago";
}else{
return 'just';
}
}
}else{
return 'just';
}
}
}else{
return 'just';
}
}
}



Example 4:



Copy code

The code is as follows:

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.'seconds ago';

}else{
if($dur < 3600){
return floor($dur/60).'minutes ago';
}else{
if($dur < 86400){
return floor($dur/3600).'hours ago';
}else{
if($dur < 259200){//Within 3 days
return floor($dur/86400).'day';
}else{
return $the_time;
}
}
}
}
}
}



2. Class implementation



Copy code

The code is as follows:

/*
* 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();
            }

                                                                                                                                                                                    exit();
        }

                                                                                                                            exit() ;
          }

}

}
//Usage examples of the class
/*

*

* Call the class output method

*

* $a = new Mygettime(time(),strtotime( '-25 month'));
* echo iconv('utf-8', 'gb2312', $a->index())?iconv('utf-8', 'gb2312', $a- >index()):iconv('utf-8', 'gb2312', 'current');
*
