如何找到自2010-04-28 17:25:43之类的日期时间戳以来经过的时间，最终输出文字应该像xx Minutes Ago / xx Days Ago
答案 0 :(得分：225)
大多数答案似乎都集中在将日期从字符串转换为时间。看起来你大部分时间都在考虑将日期纳入“5天前”格式等等。对吗？
这就是我要这样做的方式：
$time = strtotime('2010-04-28 17:25:43');
echo 'event happened '.humanTiming($time).' ago';
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':'');
}
}
我没有测试过，但它应该有效。
结果看起来像
event happened 4 days ago
或
event happened 1 minute ago

想要分享php功能，这会导致语法正确的Facebook，如人类可读的时间格式。
示例：
echo get_time_ago(strtotime('now'));
结果：
不到1分钟前
function get_time_ago($time_stamp)
{
$time_difference = strtotime('now') - $time_stamp;
if ($time_difference >= 60 * 60 * 24 * 365.242199)
{
/*
* 60 seconds/minute * 60 minutes/hour * 24 hours/day * 365.242199 days/year
* This means that the time difference is 1 year or more
*/
return get_time_ago_string($time_stamp, 60 * 60 * 24 * 365.242199, 'year');
}
elseif ($time_difference >= 60 * 60 * 24 * 30.4368499)
{
/*
* 60 seconds/minute * 60 minutes/hour * 24 hours/day * 30.4368499 days/month
* This means that the time difference is 1 month or more
*/
return get_time_ago_string($time_stamp, 60 * 60 * 24 * 30.4368499, 'month');
}
elseif ($time_difference >= 60 * 60 * 24 * 7)
{
/*
* 60 seconds/minute * 60 minutes/hour * 24 hours/day * 7 days/week
* This means that the time difference is 1 week or more
*/
return get_time_ago_string($time_stamp, 60 * 60 * 24 * 7, 'week');
}
elseif ($time_difference >= 60 * 60 * 24)
{
/*
* 60 seconds/minute * 60 minutes/hour * 24 hours/day
* This means that the time difference is 1 day or more
*/
return get_time_ago_string($time_stamp, 60 * 60 * 24, 'day');
}
elseif ($time_difference >= 60 * 60)
{
/*
* 60 seconds/minute * 60 minutes/hour
* This means that the time difference is 1 hour or more
*/
return get_time_ago_string($time_stamp, 60 * 60, 'hour');
}
else
{
/*

*/
return get_time_ago_string($time_stamp, 60, 'minute');
}
}

// TODO: This pluralizes the time unit, which is done by adding "s" at the end; this will not work for i18n!

我认为我有一个应该做你想做的功能：
function time2string($timeline) {
$periods = array('day' => 86400, 'hour' => 3600, 'minute' => 60, 'second' => 1);
foreach($periods AS $name => $seconds){
$num = floor($timeline / $seconds);
$timeline -= ($num * $seconds);
$ret .= $num.' '.$name.(($num > 1) ? 's' : '').' ';
}
return trim($ret);
}
只需将其应用于time()和strtotime('2010-04-28 17:25:43')之间的差异即可：
print time2string(time()-strtotime('2010-04-28 17:25:43')).' ago';

如果你使用php Datetime类，你可以使用：
function time_ago(Datetime $date) {
$time_ago = '';
$diff = $date->diff(new Datetime('now'));
if (($t = $diff->format("%m")) > 0)
$time_ago = $t . ' months';
else if (($t = $diff->format("%d")) > 0)
$time_ago = $t . ' days';
else if (($t = $diff->format("%H")) > 0)
$time_ago = $t . ' hours';
else
$time_ago = 'minutes';
return $time_ago . ' ago (' . $date->format('M j, Y') . ')';
}
答案 4 :(得分：3)
请注意，大多数数学计算的示例都有2038-01-18个日期的严格限制，并且不适用于虚构日期。
由于缺少基于DateTime和DateInterval的示例，我想提供一个满足OP需求的多功能功能，以及其他想要复合经过时间的功能，例如{{1} }。与一堆其他用例一起，例如显示日期而不是经过时间的限制，或过滤掉经过时间结果的部分。
此外，大多数示例假设已经过了当前时间，其中下面的函数允许用期望的结束日期覆盖它。
1 month 2 days ago有一点需要注意 - 提供的过滤器值的检索间隔不会延续到下一个周期。过滤器仅显示所提供期间的结果值，并且不会重新计算期间以仅显示所需的过滤器总数。
<强>用法
OP需要显示最高时期（截至2015-02-24）。
/**
* multi-purpose function to calculate the time elapsed between $start and optional $end
* @param string|null $start the date string to start calculation
* @param string|null $end the date string to end calculation
* @param string $suffix the suffix string to include in the calculated string
* @param string $format the format of the resulting date if limit is reached or no periods were found
* @param string $separator the separator between periods to use when filter is not true
* @param null|string $limit date string to stop calculations on and display the date if reached - ex: 1 month
* @param bool|array $filter false to display all periods, true to display first period matching the minimum, or array of periods to display ['year', 'month']
* @param int $minimum the minimum value needed to include a period
* @return string
*/
function elapsedTimeString($start, $end = null, $limit = null, $filter = true, $suffix = 'ago', $format = 'Y-m-d', $separator = ' ', $minimum = 1)
{
$dates = (object) array(
'start' => new DateTime($start ? : 'now'),
'end' => new DateTime($end ? : 'now'),
'intervals' => array('y' => 'year', 'm' => 'month', 'd' => 'day', 'h' => 'hour', 'i' => 'minute', 's' => 'second'),
'periods' => array()
);
$elapsed = (object) array(
'interval' => $dates->start->diff($dates->end),
'unknown' => 'unknown'
);
if ($elapsed->interval->invert === 1) {
return trim('0 seconds ' . $suffix);
}
if (false === empty($limit)) {
$dates->limit = new DateTime($limit);
if (date_create()->add($elapsed->interval) > $dates->limit) {
return $dates->start->format($format) ? : $elapsed->unknown;
}
}
if (true === is_array($filter)) {
$dates->intervals = array_intersect($dates->intervals, $filter);
$filter = false;
}
foreach ($dates->intervals as $period => $name) {
$value = $elapsed->interval->$period;
if ($value >= $minimum) {
$dates->periods[] = vsprintf('%1$s %2$s%3$s', array($value, $name, ($value !== 1 ? 's' : '')));
if (true === $filter) {
break;
}
}
}
if (false === empty($dates->periods)) {
return trim(vsprintf('%1$s %2$s', array(implode($separator, $dates->periods), $suffix)));
}
return $dates->start->format($format) ? : $elapsed->unknown;
}
显示复合句点并提供自定义结束日期（请注意缺少时间和虚构日期）。
echo elapsedTimeString('2010-04-26');
/** 4 years ago */
显示过滤期的结果（数组排序无关紧要）。
echo elapsedTimeString('1920-01-01', '2500-02-24', null, false);
/** 580 years 1 month 23 days ago */
如果达到限制，以所提供的格式显示开始日期（默认为Y-m-d）。
echo elapsedTimeString('2010-05-26', '2012-02-24', null, ['month', 'year']);
/** 1 year 8 months ago */
还有很多其他用例。它也可以很容易地适用于接受开始，结束或限制参数的unix时间戳和/或DateInterval对象。

可以与任何版本的PHP一起使用的一个选项是执行已经建议的内容，如下所示：
$eventTime = '2010-04-28 17:25:43';
$age = time() - strtotime($eventTime);
这会给你几秒钟的年龄。从那里，您可以随意显示它。
然而，这种方法的一个问题是它不会考虑DST引起的时间偏移。如果这不是一个问题，那就去吧。否则，您可能想要使用diff() method in the DateTime class。不幸的是，如果你至少使用PHP 5.3，这只是一个选项。

// Step 1: Take the major result and transform it into raw seconds (it will be less the number of seconds of the difference)
// ex: $result = ($results['major']['weeks']*WEEK)
// Step 2: Subtract smaller number (the result) from the difference (total time)
// ex: $minor_result = $difference - $result
// Step 3: Take the resulting time in seconds and convert it to the minor format
// ex: floor($minor_result/DAY)
$results1['weeks'] = floor($diffrence / WEEK);

$results1['seconds'] = floor((($diffrence - ($results['major']['minutes'] * MINUTE)) / SECOND));
//print_r($results1);
if ($results1['weeks'] != 0 && $results1['days'] == 0) {

要查找已用时间，我通常使用time()代替date()和格式化的时间戳。
然后得到后一个值和早期值之间的差异并相应地格式化。 time()不同于date()的替代品，但在计算经过时间时完全有帮助。
示例：
time()的值看起来像这样1274467343每秒递增一次。因此，您可以$erlierTime的值为1274467343，$latterTime的值为1274467500，然后只需$latterTime - $erlierTime即可获得时间，以秒为单位。

将[saved_date]转换为时间戳。获取当前时间戳。
当前时间戳 - [saved_date]时间戳。
然后你可以用date（）;
格式化它您通常可以使用strtotime（）函数将大多数日期格式转换为时间戳。
