我不知道为什么还没有人提到碳。

https://github.com/briannesbitt/Carbon

这实际上是php dateTime的扩展(这里已经使用了)，它有:diffForHumans方法。所以你所需要做的就是:

$dt = Carbon::parse('2012-9-5 23:26:11.123789');
echo $dt->diffForHumans();

更多例子:http://carbon.nesbot.com/docs/#api-humandiff

这个解决方案的优点:

它适用于未来的日期，并将在2个月等时间内返回。 你可以使用本地化来获取其他语言，多元化也很好 如果你开始用碳来做其他事情，处理日期就会变得非常容易。

您必须将时间戳的每一部分都转换为Unix时间。例如时间戳:2009-09-12 20:57:19。

((2008-1970)*365)+(8*30)+12)*24+20可以大致估算出自1970年1月1日以来的工作时间。

用这个数字乘以60，再加57，就得到了分钟数。

用这个，乘以60，再加19。

这将非常粗略和不准确地转换它。

有什么原因让你不能开始使用正常的Unix时间吗?

我通常使用它来找出当前和传递的日期时间戳之间的差异

输出

我使用以下功能几年了。它运行得很好:

    $otherDate=$timestamp;

    $secondDifference=@strtotime($now)-@strtotime($otherDate);
    $extra="";
    if ($secondDifference == 2592000) { 
    // months 
    $difference = $secondDifference/2592000; 
    $difference = round($difference,0); 
    if ($difference>1) { $extra="s"; } 
    $difference = $difference." month".$extra." ago"; 
}else if($secondDifference > 2592000)
    {$difference=timestamp($timestamp);} 
elseif ($secondDifference >= 604800) { 
    // weeks 
    $difference = $secondDifference/604800; 
    $difference = round($difference,0); 
    if ($difference>1) { $extra="s"; } 
    $difference = $difference." week".$extra." ago"; 
}

    // days 
    $difference = $secondDifference/86400;

    $difference = $difference." hour".$extra." ago";

    // hours

    if($secondDifference<=60)
