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。

我使用以下功能几年了。它运行得很好:

function timeDifference($timestamp)
{
    $otherDate=$timestamp;
    $now=@date("Y-m-d H:i:s");

    $secondDifference=@strtotime($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"; 
} 
elseif ($secondDifference >= 86400) { 
    // days 
    $difference = $secondDifference/86400; 
    $difference = round($difference,0); 
    if ($difference>1) { $extra="s"; } 
    $difference = $difference." day".$extra." ago"; 
} 
elseif ($secondDifference >= 3600) { 
    // hours 

    $difference = $secondDifference/3600; 
    $difference = round($difference,0); 
    if ($difference>1) { $extra="s"; } 
    $difference = $difference." hour".$extra." ago"; 
} 
elseif ($secondDifference < 3600) { 
    // hours 
    // for seconds (less than minute)
    if($secondDifference<=60)
    {       
        if($secondDifference==0)
        {
            $secondDifference=1;
        }
        if ($secondDifference>1) { $extra="s"; }
        $difference = $secondDifference." second".$extra." ago"; 

    }
    else
    {

$difference = $secondDifference/60; 
        if ($difference>1) { $extra="s"; }else{$extra="";}
        $difference = round($difference,0); 
        $difference = $difference." minute".$extra." ago"; 
    }
} 

$FinalDifference = $difference; 
return $FinalDifference;
}

function humanTiming ($time)
        {

            $time = time() - $time; // to get the time since that moment
            $time = ($time<1)? 1 : $time;
            $tokens = array (
                31536000 => 'year',
                2592000 => 'month',
                604800 => 'week',
                86400 => 'day',
                3600 => 'hour',
                60 => 'minute',
                1 => 'second'
            );

            foreach ($tokens as $unit => $text) {
                if ($time < $unit) continue;
                $numberOfUnits = floor($time / $unit);
                return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
            }

        }

echo humanTiming( strtotime($mytimestring) );

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?

$time_elapsed = timeAgo($time_ago); //The argument $time_ago is in timestamp (Y-m-d H:i:s)format.
