在PHP中将时间戳转换为时间，例如1天前，2天前…

234

我正在尝试转换格式的时间戳，2009-09-12 20:57:19并将其转换为类似3 minutes agoPHP 的格式。

我找到了一个有用的脚本来执行此操作，但我认为它正在寻找其他格式用作时间变量。我想要修改以使用此格式的脚本是：

function _ago($tm,$rcs = 0) {
    $cur_tm = time(); 
    $dif = $cur_tm-$tm;
    $pds = array('second','minute','hour','day','week','month','year','decade');
    $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600);

    for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]);
        $no = floor($no);
        if($no <> 1)
            $pds[$v] .='s';
        $x = sprintf("%d %s ",$no,$pds[$v]);
        if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0))
            $x .= time_ago($_tm);
        return $x;
    }

我认为在脚本的前几行中，脚本正在尝试执行以下操作（不同的日期格式数学）：

$dif = 1252809479 - 2009-09-12 20:57:19;

如何将时间戳转换为该（unix？）格式？

使用示例：

echo time_elapsed_string('2013-05-01 00:22:35');
echo time_elapsed_string('@1367367755'); # timestamp input
echo time_elapsed_string('2013-05-01 00:22:35', true);

输入可以是任何受支持的日期和时间格式。

输出：

4 months ago
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago

功能说明

function time_elapsed_string($datetime, $full = false) {
    $now = new DateTime;
    $ago = new DateTime($datetime);
    $diff = $now->diff($ago);

    $diff->w = floor($diff->d / 7);
    $diff->d -= $diff->w * 7;

    $string = array(
        'y' => 'year',
        'm' => 'month',
        'w' => 'week',
        'd' => 'day',
        'h' => 'hour',
        'i' => 'minute',
        's' => 'second',
    );
    foreach ($string as $k => &$v) {
        if ($diff->$k) {
            $v = $diff->$k . ' ' . $v . ($diff->$k > 1 ? 's' : '');
        } else {
            unset($string[$k]);
        }
    }

    if (!$full) $string = array_slice($string, 0, 1);
    return $string ? implode(', ', $string) . ' ago' : 'just now';

周部分不错，但总体而言，该函数应更灵活（$full应为字符串输入，以根据需要过滤输出）。例如time_elapsed_string($datetime, $format = "ymw")。PS Flat版本：stackoverflow.com/a/5010169/318765

至于我最后的评论：更改$full = false到$level = 7和if (!$full) $string = array_slice($string, 0, 1);对$string = array_slice($string, 0, $level);和呼叫time_elapsed_string($datetime, 2)仅获得最高的两个日期字符串。我认为这应该满足所有需求。

这不是一个好的解决方案，因为它使用30days for month，和12x30days for year，并且因此将返回无效的年份，低于<1978年。例如，它返回39年，但应该为38年。对于以下情况，它也不起作用1970

这是一个返回通用短语的函数，例如“此评论大约在多久之前发布的？”？如上所述，它并不精确，并且会有所下降，但是对于最近的日期（例如接近30年的历史，甚至更短），它使非精确人类可以了解事件发生在多久之前。对于我的应用程序效果很好。

我认为这不会产生明显的影响。 stackoverflow.com/questions/7895966/…但是我意识到，随着时间的流逝，事件已经像“几个月前”这样说了，它将不得不检查很多if（秒，分钟，小时，天，周） 。因此，我建议您可以将这些if部分与另一个外部if（$ seconds <= 604800）一起包装。这样，几个月前的案件将不必再检查4个ifs ...再次，少于几个月的案件将有一个额外的if ....选择是您的选择。

这实际上是我发现的更好的解决方案。使用jQuery，但是效果很好。此外，它会像SO和Facebook一样自动刷新，因此您无需刷新页面即可查看更新。

此插件将datetime在<time>标签中读取您的attr 并为您填写。 

e.g. "4 minutes ago" or "about 1 day ago

我不知道为什么没人提到Carbon。

https://github.com/briannesbitt/Carbon

这实际上是php dateTime的扩展（已在此处使用），它具有：diffForHumans方法。因此，您需要做的就是：

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

更多示例：http : //carbon.nesbot.com/docs/#api-humandiff

该解决方案的优点：

  • 它适用于将来的日期，并且会在2个月内返回类似内容，依此类推。
  • 您可以使用本地化来获取其他语言，并且复数工作正常
  • 如果您将开始使用Carbon进行其他操作，那么使用日期将变得从未如此简单。

我发现以下丑陋的结果：

1年2个月0天0小时53分钟1秒

因此，我实现了一个尊重复数，删除空值的函数，并且可以选择缩短输出：

function since($timestamp, $level=6) {
    global $lang;
    $date = new DateTime();
    $date->setTimestamp($timestamp);
    $date = $date->diff(new DateTime());
    // build array
    $since = array_combine(array('year', 'month', 'day', 'hour', 'minute', 'second'), explode(',', $date->format('%y,%m,%d,%h,%i,%s')));
    // remove empty date values
    $since = array_filter($since);
    // output only the first x date values
    $since = array_slice($since, 0, $level);
    // build string
    $last_key = key(array_slice($since, -1, 1, true));
    $string = '';
    foreach ($since as $key => $val) {
        // separator
        if ($string) {
            $string .= $key != $last_key ? ', ' : ' ' . $lang['and'] . ' ';
        }
        // set plural
        $key .= $val > 1 ? 's' : '';
        // add date value
        $string .= $val . ' ' . $lang[ $key ];
    }
    return $string;
}

看起来好多了：

1年2个月53分1秒

可以选择使用$level = 2来缩短它，如下所示：

1年2个月

$lang如果只需要英语，请删除该部分，或者根据需要编辑此翻译：

$lang = array(
    'second' => 'Sekunde',
    'seconds' => 'Sekunden',
    'minute' => 'Minute',
    'minutes' => 'Minuten',
    'hour' => 'Stunde',
    'hours' => 'Stunden',
    'day' => 'Tag',
    'days' => 'Tage',
    'month' => 'Monat',
    'months' => 'Monate',
    'year' => 'Jahr',
    'years' => 'Jahre',
    'and' => 'und',

总而言之，这对我来说效果很好。虽然它没有显示出去还是更早，但是可以双向工作。轻松解决：if（$ date-> invert> 0）{$ ending =“ to go”; } else {$ ending =“ ago”; 只需将$ ending添加到$ string中。

真的很棒 感谢你的分享。但是在某些情况下，该函数返回$ numberOfUnits为空，并且仅输出“ ago”。似乎是因为该值小于1秒。在这种情况下，如果您可以将其默认设置为“ just now”（刚好），那将是完美的。

  $dif = $cur_tm - $tm;
  $pds = array('second','minute','hour','day','week','month','year','decade');

  for ($v = count($lngh) - 1; ($v >= 0) && (($no = $dif / $lngh[$v]) <= 1); $v--);
    if ($v < 0)
      $v = 0;
  $_tm = $cur_tm - ($dif % $lngh[$v]);

  $no = ($rcs ? floor($no) : round($no)); // if last denomination, round

  if ($no != 1)
    $pds[$v] .= 's';
  $x = $no . ' ' . $pds[$v];

我知道这里有几个答案，但这就是我想出的。这仅根据我响应的原始问题处理MySQL DATETIME值。数组$ a需要一些工作。我欢迎就如何改进发表评论。致电为：

    // Current time as Unix timestamp

    // Elapsed time
    $etime = $ctime - $ptime;

    // If no elapsed time, return 0
    if ($etime < 1){

我尝试了这个并且对我来说很好

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-10');
$difference = $datetime1->diff($datetime2);
echo formatOutput($difference);

function formatOutput($diff){
    /* function to return the highrst defference fount */
    if(!is_object($diff)){
        return;
    }

    if($diff->y > 0){
        return $diff->y .(" year".($diff->y > 1?"s":"")." ago");
    }

    if($diff->m > 0){
        return $diff->m .(" month".($diff->m > 1?"s":"")." ago");
    }

    if($diff->d > 0){
        return $diff->d .(" day".($diff->d > 1?"s":"")." ago");
    }

    if($diff->h > 0){
        return $diff->h .(" hour".($diff->h > 1?"s":"")." ago");
    }

    if($diff->i > 0){
        return $diff->i .(" minute".($diff->i > 1?"s":"")." ago");
    }

这里的许多解决方案都没有考虑到四舍五入。例如：

活动发生在两天前的下午3点。如果您在下午2点检查，它将在一天前显示。如果您在下午4点检查，它将在两天前显示。

如果您使用的是unix时间，这将有助于：

// how long since event has passed in seconds
$secs = time() - $time_ago;

// how many seconds in a day
$sec_per_day = 60*60*24;

// days elapsed
$days_elapsed = floor($secs / $sec_per_day);

// how many seconds passed today
$today_seconds = date('G')*3600 + date('i') * 60 + date('s');

// how many seconds passed in the final day calculation
$remain_seconds = $secs % $sec_per_day;

if($today_seconds < $remain_seconds)
{
    $days_elapsed++;
}

echo 'The event was '.$days_ago.' days ago.';

如果您担心leap秒和夏令时，那是不完美的。

尝试一下，我从旧代码中找到了它，它显示了正确的结果

function ago($datefrom, $dateto = -1) {
    // Defaults and assume if 0 is passed in that
    // its an error rather than the epoch

    if ($datefrom == 0) {
        return "A long time ago";
    }
    if ($dateto == -1) {
        $dateto = time();
    }

    // Make the entered date into Unix timestamp from MySQL datetime field

    $datefrom = strtotime($datefrom);

    // Calculate the difference in seconds betweeen
    // the two timestamps

    $difference = $dateto - $datefrom;

    // Based on the interval, determine the
    // number of units between the two dates
    // From this point on, you would be hard
    // pushed telling the difference between
    // this function and DateDiff. If the $datediff
    // returned is 1, be sure to return the singular
    // of the unit, e.g. 'day' rather 'days'

    switch (true) {
        // If difference is less than 60 seconds,
        // seconds is a good interval of choice
        case(strtotime('-1 min', $dateto) < $datefrom):

您必须获取时间戳的每个部分，并将其转换为Unix时间。例如，时间戳记为2009-09-12 20:57:19。

（（（（2008-1970）* 365）+（8 * 30）+12）* 24 + 20将为您提供自1970年1月1日以来的粗略估计。

将该数字乘以60并加57得到分钟。

乘以60，再加上19。

但是，那将非常粗略和不准确地转换它。

您有什么理由不能只花正常的Unix时间开始吗？

在UNIX表中存储为UNIX时间会更好吗？我正在时间戳列上使用mysqls自动时间戳更新（可以更改为Unix）。我只是在学习什么更好？
— willdanceforfun
绝对是 我相信mySQL表的默认值是您引用的类型，但是Unix时间要实用得多。您始终可以将其存储为int。
— LukeWarm74
您的数据库应具有将日期转换为UNIX格式的功能。在mysql中，您使用UNIX_TIMESTAMP（）。哦，通常应该将日期存储为DATETIME而不是INT，以便可以将sql函数用于日期操作。
— CpnCrunch 2013年
您永远都不要准时使用数学。您假设一个固定的日历不存在。使用php中提供的Date对象来处理日期。

用于：

echo elapsed_time('2016-05-09 17:00:00'); // 18 saat 8 dakika önce yazıldı.

功能：

function elapsed_time($time){// Nekadar zaman geçmiş

        $diff = time() - strtotime($time); 

        $sec = $diff;
        $min = floor($diff/60);

从上面略作修改的答案：

  $commentTime = strtotime($whatever)
  $today       = strtotime('today');
  $yesterday   = strtotime('yesterday');
  $todaysHours = strtotime('now') - strtotime('today');

private function timeElapsedString(
    $commentTime,
    $todaysHours,
    $today,
    $yesterday
) {
    $tokens = array(
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );
    $time = time() - $commentTime;
    $time = ($time < 1) ? 1 : $time;
    if ($commentTime >= $today || $commentTime < $yesterday) {
        foreach ($tokens as $unit => $text) {
            if ($time < $unit) {
                continue;
            }
            if ($text == 'day') {
                $numberOfUnits = floor(($time - $todaysHours) / $unit) + 1;
            } else {
                $numberOfUnits = floor(($time)/ $unit);
            }
            return $numberOfUnits . ' ' . $text . (($numberOfUnits > 1) ? 's' : '') . ' ago';
        }
    } else {
        return 'Yesterday';

以下是一个非常简单且极为有效的解决方案。

function timeElapsed($originalTime){

        $timeElapsed=time()-$originalTime;

        /*
          You can change the values of the following 2 variables 
          based on your opinion. For 100% accuracy, you can call
          php's cal_days_in_month() and do some additional coding
          using the values you get for each month. After all the
          coding, your final answer will be approximately equal to
          mine. That is why it is okay to simply use the average
          values below.
        */
        $averageNumbDaysPerMonth=(365.242/12);
        $averageNumbWeeksPerMonth=($averageNumbDaysPerMonth/7);

        $time1=(((($timeElapsed/60)/60)/24)/365.242);
        $time2=floor($time1);//Years
        $time3=($time1-$time2)*(365.242);
        $time4=($time3/$averageNumbDaysPerMonth);
        $time5=floor($time4);//Months
        $time6=($time4-$time5)*$averageNumbWeeksPerMonth;
        $time7=floor($time6);//Weeks
        $time8=($time6-$time7)*7;
        $time9=floor($time8);//Days
        $time10=($time8-$time9)*24;
        $time11=floor($time10);//Hours
        $time12=($time10-$time11)*60;
        $time13=floor($time12);//Minutes
        $time14=($time12-$time13)*60;
        $time15=round($time14);//Seconds

        $timeElapsed=$time2 . 'yrs ' . $time5 . 'months ' . $time7 . 
                     'weeks ' . $time9 .  'days ' . $time11 . 'hrs '
                     . $time13 . 'mins and ' . $time15 . 'secs.';

        return $timeElapsed;

}

echo timeElapsed（1201570814）;

这是我前段时间构建的通知模块的解决方案。它返回类似于Facebook的通知下拉列表的输出（例如1天前，刚才等）。

public function getTimeDifference($time) {
    //Let's set the current time
    $currentTime = date('Y-m-d H:i:s');
    $toTime = strtotime($currentTime);

    //And the time the notification was set
    $fromTime = strtotime($time);

    //Now calc the difference between the two
    $timeDiff = floor(abs($toTime - $fromTime) / 60);

    //Now we need find out whether or not the time difference needs to be in
    //minutes, hours, or days
    if ($timeDiff < 2) {
        $timeDiff = "Just now";
    } elseif ($timeDiff > 2 && $timeDiff < 60) {
        $timeDiff = floor(abs($timeDiff)) . " minutes ago";
    } elseif ($timeDiff > 60 && $timeDiff < 120) {
        $timeDiff = floor(abs($timeDiff / 60)) . " hour ago";
    } elseif ($timeDiff < 1440) {
        $timeDiff = floor(abs($timeDiff / 60)) . " hours ago";
    } elseif ($timeDiff > 1440 && $timeDiff < 2880) {
        $timeDiff = floor(abs($timeDiff / 1440)) . " day ago";
    } elseif ($timeDiff > 2880) {
        $timeDiff = floor(abs($timeDiff / 1440)) . " days ago";
    }

    return $timeDiff;
}

只需将日期时间传递到此函数即可。它会以您之前的时间格式打印出来

date_default_timezone_set('your-time-zone');
function convert($datetime){
  $time=strtotime($datetime);
  $diff=time()-$time;
  $diff/=60;
  $var1=floor($diff);
  $var=$var1<=1 ? 'min' : 'mins';
  if($diff>=60){
    $diff/=60;
    $var1=floor($diff);
    $var=$var1<=1 ? 'hr' : 'hrs';
    if($diff>=24){$diff/=24;$var1=floor($diff);$var=$var1<=1 ? 'day' : 'days';
    if($diff>=30.4375){$diff/=30.4375;$var1=floor($diff);$var=$var1<=1 ? 'month' : 'months';
    if($diff>=12){$diff/=12;$var1=floor($diff);$var=$var1<=1 ? 'year' : 'years';}}}}
    echo $var1,' ',$var,' ago';

我正在使用以下功能几年。它工作正常：

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;
