PHP CodeBase: 将时间显示为“刚刚”“n分钟/小时前”等

Jun 13, 2016 am 10:53 AM
php for for information exist Will Hour time show of

在很多场合为了显示出信息的及时性,一般会将时间显示成“刚刚”,“5分钟前”,“3小时前”等,而不是直接将时间打印出来。比如微博,SNS类应用就最长用到这个功能。而一般存储在数据库中的时间格式为 Unix时间戳,所以这里记录一个将 Unix时间戳 转化为时间轴显示的PHP函数。

函数比较简单,直接看代码就很好懂了。

date_default_timezone_set('PRC');
$date = "1351836000";
echo tranTime($date);

function transfer_time($time)
{
    $rtime = date("m-d H:i",$time);
    $htime = date("H:i",$time);

    $time = time() - $time;

    if ($time     {
        $str = '刚刚';
    }
    elseif ($time     {
        $min = floor($time/60);
        $str = $min.'分钟前';
    }
    elseif ($time     {
        $h = floor($time/(60*60));
        $str = $h.'小时前 '.$htime;
    }
    elseif ($time     {
        $d = floor($time/(60*60*24));
        if($d==1)
            $str = '昨天 '.$rtime;
        else
            $str = '前天 '.$rtime;
    }
    else
    {
        $str = $rtime;
    }
    return $str;
}

?>

注意函数transfer_time()中的参数$time必须为Unix时间戳,如果不是请先用strtotime()将其转换成Unix时间戳
