php显示文章 几分钟前,几小时前,几天前发布类
文章发表时的UNIX时间戳,来转化为例如,几分钟前,几小时前,几天前....这样的提示,如微博,这看起来更加人性化,类代码如下:
- <?php
- class timeAgo
- {
- static $timeagoObject;
- private $rustle;
- private $unit;
- private function __construct()

- self::$timeagoObject = new timeAgo();
- return self::$timeagoObject;
- }
- private function count_int($unix_C) // main function
- {
- if(! (isset($unix_C) || is_numeric($unix_C)) )
- return 'don't find parameter';
- $d = time()-$unix_C ; // $d - unix time difference value
- $d_int =(int)floor($d/60) ; // minimum unit -- minutes unix/60
- $this->unit = 0 ; // is minutes,hour or day?
- if($d_int < 60){ // minutes in one hour 3600
- $this->rustle = $d_int;
- $this->unit = 1;
- }
- else if($d_int < 720){ //hour in one day 3600*12

- }

- $this->rustle = floor($d_int/720);
- $this->unit = 3 ;
- }
- else{
- $this->rustle = $d ;
- $this->unit = 4 ;
- }
- }
