我正在尝试转换格式为2009-09-12 20:57:19的时间戳，并将其转换为类似3 minutes ago的PHP。
我找到了一个有用的脚本来做到这一点，但我认为它正在寻找一种不同的格式作为时间变量。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）：
$dif = 1252809479 - 2009-09-12 20:57:19;
我如何将我的时间戳转换为（unix？）格式？
echo time_elapsed_string('2013-05-01 00:22:35');
echo time_elapsed_string('@1367367755'); # timestamp input
echo time_elapsed_string('2013-05-01 00:22:35', true);
输入可以是任何supported date and time format。
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago
function time_elapsed_string($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(', ', $string) . ' ago' : 'just now';
}
我做了这个，它工作得很好，它适用于像1470919932这样的unix时间戳或像16-08-11 14:53:30这样的格式化时间
function timeAgo($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;
}
?>
它可以帮助你检查它

我知道这里有几个答案，但这就是我想出来的。这只根据我回复的原始问题处理MySQL DATETIME值。数组$ a需要一些工作。我欢迎有关如何改进的意见。呼叫：
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';
}
我试过这个，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");
}
if($diff->s > 0){
return $diff->s .(" second".($diff->s > 1?"s":"")." ago");
}
}

这就是我的用途。这是阿巴斯汗的帖子的修改版本：

这里的许多解决方案都不考虑舍入。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。
如果您正在使用unix时间，这有助于：
// 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.';
如果您担心闰秒和夏令时，这并不完美。
你必须把每个单独的时间戳记转换成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。
取这个数字，乘以60并加57得到分钟数。
拿它，乘以60并加19。
然而，这将非常粗略和不准确地转换它。
你有什么理由不能开始正常的Unix时间吗？
某些语言显示时间存在问题，例如在阿拉伯语中有3种需要格式来显示日期。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，我将是apperciate :)）

这是我前一段时间建立的通知模块的解决方案。它返回的输出类似于Facebook的通知下拉列表（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 $timeDiff;
}
只需将日期时间传递给此函数。它会为你准备好时间格式
date_default_timezone_set('your-time-zone');
function convert($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';
}
我使用以下功能已有好几年了。它工作正常：
function timeDifference($timestamp)

$otherDate=$timestamp;
$now=@date("Y-m-d H:i:s");
$secondDifference=@strtotime($now)-@strtotime($otherDate);
$extra="";

$difference = round($difference,0);

$difference = $difference." month".$extra." ago";
}else if($secondDifference > 2592000)
{$difference=timestamp($timestamp);}

$difference = $secondDifference/604800;
$difference = round($difference,0);

}
}
$FinalDifference = $difference;
return $FinalDifference;
}
$time_elapsed = timeAgo($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 ;

这实际上是我发现的更好的解决方案。使用jQuery然而它完美地工作。它也会自动刷新，类似于SO和Facebook的方式，因此您无需刷新页面即可查看更新。
这个插件将在datetime标签中读取你的<time> attr并为你填写。
e.g. "4 minutes ago" or "about 1 day ago
我不知道为什么没有人提到碳。
https://github.com/briannesbitt/Carbon
这实际上是php dateTime（这里已经使用过）的扩展，它有：diffForHumans方法。所以你需要做的就是：
$dt = Carbon::parse('2012-9-5 23:26:11.123789');
echo $dt->diffForHumans();
更多例子：http://carbon.nesbot.com/docs/#api-humandiff
这个解决方案的优点：
function humanTiming ($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) );
我发现结果如下丑：
1年，2个月，0天，0小时，53分钟和1秒
因此，我实现了一个尊重复数的函数，删除空值，并可选择缩短输出：
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 $string;
}
看起来好多了：
1年，2个月，53分钟和1秒
可以选择使用$level = 2来缩短它，如下所示：
1年零2个月
如果您只需要英文版本，请删除$lang部分或编辑此翻译以满足您的需求：
$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',
);
我稍微修改了原始函数（在我看来更有用，或逻辑上）。
// 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;
}
只是扔另一种选择......
虽然我更喜欢发布here的DateTime方法，但我不喜欢它显示0年等事实。
