【中文标题】像facebook消息系统一样计算时差[重复]

【英文标题】：calculate time difference like facebook messaging system [duplicate]

【发布时间】：2012-07-17 09:58:37

【问题描述】：

我需要使用 php 在 facebook 消息中查找 like 的时差。

like: 2 weeks ago, 2 hr 30 mins ago, one second ago

我的时间格式是“Y-m-d H:i:s”

谁能帮帮我？

【问题讨论】：

我只能用 dayz 找到它，不能用小时分钟和秒找到它。

【参考方案1】：

将消息创建时间存储在数据库中，然后使用以下函数：

function get_time_difference_php($created_time)
 
        date_default_timezone_set('Asia/Calcutta'); //Change as per your default time
        $str = strtotime($created_time);
        $today = strtotime(date('Y-m-d H:i:s'));

        // It returns the time difference in Seconds...
        $time_differnce = $today-$str;

        // To Calculate the time difference in Years...
        $years = 60*60*24*365;

        // To Calculate the time difference in Months...
        $months = 60*60*24*30;

        // To Calculate the time difference in Days...
        $days = 60*60*24;

        // To Calculate the time difference in Hours...
        $hours = 60*60;

        // To Calculate the time difference in Minutes...
        $minutes = 60;

        if(intval($time_differnce/$years) > 1)
        
            return intval($time_differnce/$years)." years ago";
        else if(intval($time_differnce/$years) > 0)
        
            return intval($time_differnce/$years)." year ago";
        else if(intval($time_differnce/$months) > 1)
        
            return intval($time_differnce/$months)." months ago";
        else if(intval(($time_differnce/$months)) > 0)
        
            return intval(($time_differnce/$months))." month ago";
        else if(intval(($time_differnce/$days)) > 1)
        
            return intval(($time_differnce/$days))." days ago";
        else if (intval(($time_differnce/$days)) > 0) 
        
            return intval(($time_differnce/$days))." day ago";
        else if (intval(($time_differnce/$hours)) > 1) 
        
            return intval(($time_differnce/$hours))." hours ago";
        else if (intval(($time_differnce/$hours)) > 0) 
        
            return intval(($time_differnce/$hours))." hour ago";
        else if (intval(($time_differnce/$minutes)) > 1) 
        
            return intval(($time_differnce/$minutes))." minutes ago";
        else if (intval(($time_differnce/$minutes)) > 0) 
        
            return intval(($time_differnce/$minutes))." minute ago";
        else if (intval(($time_differnce)) > 1) 
        
            return intval(($time_differnce))." seconds ago";
        else
        
            return "few seconds ago";
