PHP：从时间戳生成相对日期/时间

我基本上试图将Unix时间戳（time（）函数）转换为与过去和未来日期兼容的相对日期/时间。 所以产出可以是：

2个星期前

1小时和60分钟前

15分54秒前

10分钟和15秒后

首先，我尝试编码，但做了一个巨大的不可维护的功能，然后我搜索了几个小时的互联网，但我能找到的只是一部分时间的脚本（eh：“1小时前”，没有纪要）。

你有脚本已经做到了吗？

此功能可以在“现在”和“特定时间戳”之间给出“1小时前”或“明天”结果。

function time2str($ts)
{
    if(!ctype_digit($ts))
        $ts = strtotime($ts);

    $diff = time() - $ts;
    if($diff == 0)
        return 'now';
    elseif($diff > 0)
    {
        $day_diff = floor($diff / 86400);
        if($day_diff == 0)
        {
            if($diff < 60) return 'just now';
            if($diff < 120) return '1 minute ago';
            if($diff < 3600) return floor($diff / 60) . ' minutes ago';
            if($diff < 7200) return '1 hour ago';
            if($diff < 86400) return floor($diff / 3600) . ' hours ago';
        }
        if($day_diff == 1) return 'Yesterday';
        if($day_diff < 7) return $day_diff . ' days ago';
        if($day_diff < 31) return ceil($day_diff / 7) . ' weeks ago';
        if($day_diff < 60) return 'last month';
        return date('F Y', $ts);
    }
    else
    {
        $diff = abs($diff);
        $day_diff = floor($diff / 86400);
        if($day_diff == 0)
        {
            if($diff < 120) return 'in a minute';
            if($diff < 3600) return 'in ' . floor($diff / 60) . ' minutes';
            if($diff < 7200) return 'in an hour';
            if($diff < 86400) return 'in ' . floor($diff / 3600) . ' hours';
        }
        if($day_diff == 1) return 'Tomorrow';
        if($day_diff < 4) return date('l', $ts);
        if($day_diff < 7 + (7 - date('w'))) return 'next week';
        if(ceil($day_diff / 7) < 4) return 'in ' . ceil($day_diff / 7) . ' weeks';
        if(date('n', $ts) == date('n') + 1) return 'next month';
        return date('F Y', $ts);
    }
}

function relativeTime($time) {

    $d[0] = array(1,"second");
    $d[1] = array(60,"minute");
    $d[2] = array(3600,"hour");
    $d[3] = array(86400,"day");
    $d[4] = array(604800,"week");
    $d[5] = array(2592000,"month");
    $d[6] = array(31104000,"year");

    $w = array();

    $return = "";
    $now = time();
    $diff = ($now-$time);
    $secondsLeft = $diff;

    for($i=6;$i>-1;$i--)
    {
         $w[$i] = intval($secondsLeft/$d[$i][0]);
         $secondsLeft -= ($w[$i]*$d[$i][0]);
         if($w[$i]!=0)
         {
            $return.= abs($w[$i]) . " " . $d[$i][1] . (($w[$i]>1)?'s':'') ." ";
         }

    }

    $return .= ($diff>0)?"ago":"left";
    return $return;
}

用法：

echo relativeTime((time()-256));
4 minutes 16 seconds ago

这是我写的。 显示相对于今天日期的过去日期。

/**
 * @param $date integer of unixtimestamp format, not actual date type
 * @return string
 */
function zdateRelative($date)
{
    $now = time();
    $diff = $now - $date;

    if ($diff < 60){
        return sprintf($diff > 1 ? '%s seconds ago' : 'a second ago', $diff);
    }

    $diff = floor($diff/60);

    if ($diff < 60){
        return sprintf($diff > 1 ? '%s minutes ago' : 'one minute ago', $diff);
    }

    $diff = floor($diff/60);

    if ($diff < 24){
        return sprintf($diff > 1 ? '%s hours ago' : 'an hour ago', $diff);
    }

    $diff = floor($diff/24);

    if ($diff < 7){
        return sprintf($diff > 1 ? '%s days ago' : 'yesterday', $diff);
    }

    if ($diff < 30)
    {
        $diff = floor($diff / 7);

        return sprintf($diff > 1 ? '%s weeks ago' : 'one week ago', $diff);
    }

    $diff = floor($diff/30);

    if ($diff < 12){
        return sprintf($diff > 1 ? '%s months ago' : 'last month', $diff);
    }

    $diff = date('Y', $now) - date('Y', $date);

    return sprintf($diff > 1 ? '%s years ago' : 'last year', $diff);
}
