PHP把时间转换成几分钟前、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:


实例2:


实例3:
	//echo 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';
        }
    }
}
echo format_date("1404600000");
?>

实例4:
 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';
       }
    }
}
echo formatTime("2014-7-8 19:22:01");
?>



二、类的实现
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');
 *
 */
