Question

我有一个脚本，用于检查条目添加到数据库的日期和时间，将其与今天的日期和时间进行比较，并输出最相关单位（分钟，小时，天，周等）的差异。 / p>

问题是，任何超过一周的条目仅显示为“6天前添加。”

我在计算时差方面显然有一些问题，但我似乎无法识别它。

这是我的代码：

    $date_time_added = $date_added . $time_added;
    $current_date_time = $current_date . $current_time;

    // Check how many X ago comment was added
    $diff = abs(strtotime($current_date_time) - strtotime($date_time_added));
    $years = floor($diff / (365*60*60*24));
    $months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
    $days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
    $hours = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24)/ (60*60));    
    $minutes  = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24 - $hours*60*60)/ 60);
    $seconds = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24 - $hours*60*60 - $minuts*60));   
    // Check if comment was added in last 24 hours
    if ($days < '1') {
        // Check if comment was added in the last hour
        if($hours == 0) {
            // Check if comment wass added in the last minute
            if ($minutes == 0) {
                $when = 'Posted ' . $seconds . ' seconds ago';
                } else {
                    $when = 'Posted ' . $minutes . ' minutes ago';              }
                } else {
                    $when = 'Posted ' . $hours . ' hours ago';
            }
    } else {
        $when = 'Posted ' . $days . ' days ago';
    }

感谢您的帮助。

Answer 1

将floor()更改为round()。此外，您在上次作业中拼错了$minutes。

为什么在计算月份时会花费多年时间？如果你只需要最相关的单位就不会这样做：

$date_time_added = $date_added . $time_added;
$current_date_time = $current_date . $current_time;

// Check how many X ago comment was added
$diff = abs(strtotime($current_date_time) - strtotime($date_time_added));
$years = floor($diff / (365*60*60*24));
$months = floor($diff / (30*60*60*24));
$days = floor($diff / (60*60*24));
$hours = floor($diff / (60*60));    
$minutes  = floor($diff / 60);
$seconds = $diff;   

if($years==0)
{
    if($months==0)
    {
        if($days==0)
        {
            if($hours==0)
            {
                if($minutes==0)
                {
                    $when='Posted '.$seconds.' seconds ago';
                }
                else
                {
                    $when='Posted '.$minutes.' minutes ago';
                }
            }
            else
            {
               $when='Posted '.$hours.' hours ago';
            }
        }
        else
        {
            $when='Posted '.$days.' days ago';
        }
    }
    else
    {
        $when='Posted '.$days.' months ago';
    }
}
else
{
    $when='Posted '.$years.' years ago';
}

我最终在我的一个项目中使用了Gareth的答案。这是一个修改后的版本，可以提供1天或1个月而不是1天或1个月。谢谢Gareth！

$diff = (strtotime("Now") - strtotime($date_time_added));
                                $years = floor($diff / (365*60*60*24));

                                $hours = floor($diff / (60*60));    
                                $minutes  = floor($diff / 60);
                                $seconds = $diff;

麻烦在PHP中计算时差
