我正在尝试转换格式为 2009-09-12 20:57:19 的时间戳，并使用 PHP 将其转换为 3 minutes ago 之类的东西。
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一种不同的格式来用作时间变量。我要修改以使用这种格式的脚本是：
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;
}
我认为在前几行中，脚本试图做一些看起来像这样的事情（不同的日期格式数学）：
$dif = 1252809479 - 2009-09-12 20:57:19;
我将如何将我的时间戳转换为那种（unix？）格式？
使用示例：
echo time_elapsed_string('2013-05-01 00:22:35');
echo time_elapsed_string('@1367367755'); # timestamp input
echo time_elapsed_string('2013-05-01 00:22:35', true);
输入可以是任何 supported date and time format。
输出 ：
4 months ago
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago
功能 ：
function time_elapsed_string($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(', ', $string) . ' ago' : 'just now';
}
function time_elapsed_string($ptime)
{
$etime = time() - $ptime;
if ($etime < 1)
{
return '0 seconds';
}
$a = array( 365 * 24 * 60 * 60 => 'year',
30 * 24 * 60 * 60 => 'month',
24 * 60 * 60 => 'day',
60 * 60 => 'hour',
60 => 'minute',
1 => 'second'
);
$a_plural = array( 'year' => 'years',
'month' => 'months',
'day' => 'days',
'hour' => 'hours',
'minute' => 'minutes',
'second' => 'seconds'
);
foreach ($a as $secs => $str)
{
$d = $etime / $secs;
if ($d >= 1)
{
$r = round($d);
return $r . ' ' . ($r > 1 ? $a_plural[$str] : $str) . ' ago';
}
}
}
30days for month 和 12x30days for year，因此它将返回低于年 <= 1978 年的无效年数。Example 它返回 39 年，但应该是 38 . 它在 1970 年以后的几年里也行不通。
$time_elapsed = timeAgo($time_ago); //The argument $time_ago is in timestamp (Y-m-d H:i:s)format.
//Function definition
function timeAgo($time_ago)
{
$time_ago = strtotime($time_ago);
$cur_time = time();
$time_elapsed = $cur_time - $time_ago;
$seconds = $time_elapsed ;
$minutes = round($time_elapsed / 60 );
$hours = round($time_elapsed / 3600);
$days = round($time_elapsed / 86400 );
$weeks = round($time_elapsed / 604800);
$months = round($time_elapsed / 2600640 );
$years = round($time_elapsed / 31207680 );
// Seconds
if($seconds <= 60){
return "just now";
}
//Minutes

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（已在此处使用），它具有：diffForHumans 方法。所以你需要做的就是：
$dt = Carbon::parse('2012-9-5 23:26:11.123789');
echo $dt->diffForHumans();
更多示例：http://carbon.nesbot.com/docs/#api-humandiff
此解决方案的优点：
它适用于未来的日期，并将在 2 个月内返回类似的东西。
您可以使用本地化来获取其他语言，并且多元化工作正常
如果您将开始将 Carbon 用于其他事情，那么使用日期将变得前所未有的简单。
这实际上是我找到的更好的解决方案。使用 jQuery，但它完美地工作。此外，它会自动刷新，类似于 SO 和 Facebook 的方式，因此您无需刷新页面即可查看更新。
该插件将读取您在 <time> 标记中的 datetime 属性并为您填写。
e.g. "4 minutes ago" or "about 1 day ago
2020-12-19 13:12:58
我发现如下丑陋的结果：
1年2个月0天0小时53分1秒
因此，我实现了一个尊重复数的函数，删除空值，并且可以选择缩短输出：
function since($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
如果您只需要英文版，请删除 $lang 部分，或编辑此翻译以满足您的需要：
$lang = array(
'second' => 'Sekunde',
'seconds' => 'Sekunden',
'minute' => 'Minute',
'minutes' => 'Minuten',
'hour' => 'Stunde',
'hours' => 'Stunden',
'day' => 'Tag',
'days' => 'Tage',
'month' => 'Monat',
'months' => 'Monate',
'year' => 'Jahr',
'years' => 'Jahre',
'and' => 'und',
);
explode 和 array_combine 的行。
global？请阅读一些 www.PhpTheRightWay.com。
function humanTiming ($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) );
我稍微修改了原始功能（在我看来更有用，或更合乎逻辑）。
// display "X time" ago, $rcs is precision depth
function time_ago ($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 = 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];
if (($rcs > 0) && ($v >= 1))
$x .= ' ' . $this->time_ago($_tm, $rcs - 1);
return $x;
}
我做了这个，它工作得很好，它适用于像 1470919932 这样的 unix 时间戳或像 16-08-11 14:53:30 这样的格式化时间
function timeAgo($time_ago) {
$time_ago = strtotime($time_ago) ? strtotime($time_ago) : $time_ago;
$time = time() - $time_ago;
switch($time):
// seconds
case $time <= 60;
return 'lessthan a minute ago';
// minutes
case $time >= 60 && $time < 3600;
return (round($time/60) == 1) ? 'a minute' : round($time/60).' minutes ago';
// hours
case $time >= 3600 && $time < 86400;
return (round($time/3600) == 1) ? 'a hour ago' : round($time/3600).' hours ago';
// days
case $time >= 86400 && $time < 604800;
return (round($time/86400) == 1) ? 'a day ago' : round($time/86400).' days ago';
// weeks
case $time >= 604800 && $time < 2600640;
return (round($time/604800) == 1) ? 'a week ago' : round($time/604800).' weeks ago';
// months
case $time >= 2600640 && $time < 31207680;
return (round($time/2600640) == 1) ? 'a month ago' : round($time/2600640).' months ago';
// years
case $time >= 31207680;
return (round($time/31207680) == 1) ? 'a year ago' : round($time/31207680).' years ago' ;
endswitch;
}
?>
$time 将评估为 true，那不应该是 switch (true) 吗？
只是为了提供另一种选择......
虽然我更喜欢发布 here 的 DateTime 方法，但我不喜欢它显示 0 年等的事实。
/*
* Returns a string stating how long ago this happened
*/
private function timeElapsedString($ptime){
$diff = time() - $ptime;
$calc_times = array();
$timeleft = array();
// Prepare array, depending on the output we want to get.
$calc_times[] = array('Year', 'Years', 31557600);
$calc_times[] = array('Month', 'Months', 2592000);
$calc_times[] = array('Day', 'Days', 86400);
$calc_times[] = array('Hour', 'Hours', 3600);
$calc_times[] = array('Minute', 'Minutes', 60);
$calc_times[] = array('Second', 'Seconds', 1);
foreach ($calc_times AS $timedata){
list($time_sing, $time_plur, $offset) = $timedata;
if ($diff >= $offset){
$left = floor($diff / $offset);
$diff -= ($left * $offset);
$timeleft[] = "{$left} " . ($left == 1 ? $time_sing : $time_plur);
}
}
return $timeleft ? (time() > $ptime ? null : '-') . implode(' ', $timeleft) : 0;
}
我通常用它来找出 current 和 passed datetime stamp 之间的区别

return $min . " minutes ago";
}else if($seconds >= 1 && $seconds <= 60){

要直接回答问题...您可以使用...
strtotime()
https://www.php.net/manual/en/function.strtotime.php
$dif = time() - strtotime("2009-09-12 20:57:19");
例如：
echo round(((( time() - strtotime("2021-08-01 21:57:50") )/60)/60)/24).' day(s) ago';
结果：1 天前
我知道这里有几个答案，但这就是我想出的。这仅根据我回答的原始问题处理 MySQL DATETIME 值。数组 $a 需要一些工作。我欢迎就如何改进提出意见。调用为：
echo time_elapsed_string('2014-11-14 09:42:28');
function time_elapsed_string($ptime)
{
// Past time as MySQL DATETIME value
$ptime = strtotime($ptime);
// Current time as MySQL DATETIME value
$csqltime = date('Y-m-d H:i:s');
// Current time as Unix timestamp
$ctime = strtotime($csqltime);
// Elapsed time
$etime = $ctime - $ptime;
// If no elapsed time, return 0
if ($etime < 1){
return '0 seconds';
}
$a = array( 365 * 24 * 60 * 60 => 'year',
30 * 24 * 60 * 60 => 'month',
24 * 60 * 60 => 'day',
60 * 60 => 'hour',
60 => 'minute',
1 => 'second'
);
$a_plural = array( 'year' => 'years',
'month' => 'months',
'day' => 'days',
'hour' => 'hours',
'minute' => 'minutes',
'second' => 'seconds'
);
foreach ($a as $secs => $str){
// Divide elapsed time by seconds
$d = $etime / $secs;
if ($d >= 1){
// Round to the next lowest integer
$r = floor($d);
// Calculate time to remove from elapsed time
$rtime = $r * $secs;
// Recalculate and store elapsed time for next loop
if(($etime - $rtime) < 0){
$etime -= ($r - 1) * $secs;
}
else{
$etime -= $rtime;
}
// Create string to return
$estring = $estring . $r . ' ' . ($r > 1 ? $a_plural[$str] : $str) . ' ';
}
}
return $estring . ' ago';
}
我试过了，对我来说效果很好
$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");
}
if($diff->s > 0){
return $diff->s .(" second".($diff->s > 1?"s":"")." ago");
}
}

这里的许多解决方案都没有考虑四舍五入。例如：
事件发生在两天前的下午 3 点。如果您在下午 2 点检查，它将显示一天前。如果您在下午 4 点检查，它将显示两天前。
如果您使用的是 unix 时间，这会有所帮助：
// 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.';
如果您担心闰秒和夏令时，这并不完美。
您必须获取时间戳的每一部分，并将其转换为 Unix 时间。例如时间戳，2009-09-12 20:57:19。
(((2008-1970)*365)+(8*30)+12)*24+20 会给你一个粗略估计自 1970 年 1 月 1 日以来的小时数。
取那个数字，乘以 60 再加上 57 得到分钟。
把它乘以 60 再加上 19。
然而，这会非常粗略且不准确地转换它。
你有什么理由不能从正常的 Unix 时间开始？
某些语言显示时间之前存在一些问题，例如在阿拉伯语中，显示日期需要 3 种格式。我在我的项目中使用这个功能希望他们可以帮助某人（任何建议或改进我都会很感激:)）

如果您使用的是 PostgreSQL，那么它将为您完成这项工作：
const DT_SQL = <<<SQL
WITH lapse AS (SELECT (?::timestamp(0) - now()::timestamp(0))::text t)
SELECT CASE
WHEN (select t from lapse) ~ '^\s*-' THEN replace((select t from lapse), '-', '') ||' ago'
ELSE (select t from lapse) END;

function timeSpanText($ts, $conn)
// $ts: date-time string, $conn: PostgreSQL PDO connection
{
return $conn -> prepare(DT_SQL) -> execute([ts]) -> fetchColumn();
}
我想要支持单数和复数的荷兰语版本。仅在末尾添加一个“s”是不够的，我们使用了完全不同的词，所以我重写了这篇文章的最佳答案。

您可能应该先对其进行测试，因为我不是那么好的程序员:)
$time_ago = ' ';
$time = time() - $time; // to get the time since that moment
$tokens = array (
31536000 => 'year',2592000 => 'month',604800 => 'week',86400 => 'day',3600 => 'hour',
60 => 'minute',1 => 'second');
foreach ($tokens as $unit => $text) {
if ($time < $unit)continue;
$numberOfUnits = floor($time / $unit);
$time_ago = ' '.$time_ago. $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'').' ';
$time = $time % $unit;}echo $time_ago;
这是我的解决方案，请根据您的要求检查和修改

date_default_timezone_set('Australia/Sydney');

以下是一个非常简单且极其有效的解决方案。

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.

//Now calc the difference between the two

//Now we need find out whether or not the time difference needs to be in
//minutes, hours, or days
if ($timeDiff < 2) {

$full应该是一个字符串输入，以根据需要过滤输出）。例如time_elapsed_string($datetime, $format = "ymw")。 PS平面版：stackoverflow.com/a/5010169/318765$full = false更改为$level = 7并将if (!$full) $string = array_slice($string, 0, 1);更改为$string = array_slice($string, 0, $level);并调用time_elapsed_string($datetime, 2)以仅获取两个最高日期字符串。我认为这应该满足所有需求。$diff->w = floor($diff->d / 7);得到Unknown property (w)Unknown property (w)，请将 $diff 从对象转换为数组并相应地调整其余代码。我在此处发布了修复：stackoverflow.com/a/32723846/235633
