一个更通用的版本，返回日，小时，分钟或秒的结果，包括分数/小数:

function DateDiffInterval($sDate1, $sDate2, $sUnit='H') {
//subtract $sDate2-$sDate1 and return the difference in $sUnit (Days,Hours,Minutes,Seconds)
    $nInterval = strtotime($sDate2) - strtotime($sDate1);
    if ($sUnit=='D') { // days
        $nInterval = $nInterval/60/60/24;
    } else if ($sUnit=='H') { // hours
        $nInterval = $nInterval/60/60;
    } else if ($sUnit=='M') { // minutes
        $nInterval = $nInterval/60;
    } else if ($sUnit=='S') { // seconds
    }
    return $nInterval;
} //DateDiffInterval

求两个日期之差的方法在这里。有了这个功能，你可以找到秒、分、小时、天、年和月等差异。

function alihan_diff_dates($date = null, $diff = "minutes") {
 $start_date = new DateTime($date);
 $since_start = $start_date->diff(new DateTime( date('Y-m-d H:i:s') )); // date now
 print_r($since_start);
 switch ($diff) {
    case 'seconds':
        return $since_start->s;
        break;
    case 'minutes':
        return $since_start->i;
        break;
    case 'hours':
        return $since_start->h;
        break;
    case 'days':
        return $since_start->d;
        break;      
    default:
        # code...
        break;
 }
}

你可以开发这个函数。我测试过了，结果对我有用。DateInterval对象输出如下:

/*
DateInterval Object ( [y] => 0 [m] => 0 [d] => 0 [h] => 0 [i] => 5 [s] => 13 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 0 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) 
*/

功能用途:

$date =过去的日期， $diff =类型eg:“分钟”，“天”，“秒”

$diff_mins = alihan_diff_dates("2019-03-24 13:24:19", "minutes");

祝你好运。

我为我的博客网站写了这个函数(过去的日期和服务器的日期之间的差异)。它会给你一个这样的输出

“49秒前”，“20分钟前”，“21小时前”等等

我使用了一个函数来获取传递的日期和服务器日期之间的差值。

<?php

//Code written by purpledesign.in Jan 2014
function dateDiff($date)
{
    $mydate= date("Y-m-d H:i:s");
    $theDiff="";
    //echo $mydate;//2014-06-06 21:35:55
    $datetime1 = date_create($date);
    $datetime2 = date_create($mydate);
    $interval = date_diff($datetime1, $datetime2);
    //echo $interval->format('%s Seconds %i Minutes %h Hours %d days %m Months %y Year    Ago')."<br>";
    $min=$interval->format('%i');
    $sec=$interval->format('%s');
    $hour=$interval->format('%h');
    $mon=$interval->format('%m');
    $day=$interval->format('%d');
    $year=$interval->format('%y');
    if($interval->format('%i%h%d%m%y')=="00000") {
        //echo $interval->format('%i%h%d%m%y')."<br>";
        return $sec." Seconds";
    } else if($interval->format('%h%d%m%y')=="0000"){
        return $min." Minutes";
    } else if($interval->format('%d%m%y')=="000"){
        return $hour." Hours";
    } else if($interval->format('%m%y')=="00"){
        return $day." Days";
    } else if($interval->format('%y')=="0"){
        return $mon." Months";
    } else{
        return $year." Years";
    }    
}
?>

以date.php为例，将其保存为文件。像这样从另一个页面调用函数

<?php
 require('date.php');
 $mydate='2014-11-14 21:35:55';
 echo "The Difference between the server's date and $mydate is:<br> ";
 echo dateDiff($mydate);
?>

当然，您可以修改函数来传递两个值。

以上答案适用于较旧版本的PHP。使用DateTime类来进行任何日期计算，因为PHP 5.3是标准的。 如。

$start_date = new DateTime('2007-09-01 04:10:58');
$since_start = $start_date->diff(new DateTime('2012-09-11 10:25:00'));
echo $since_start->days.' days total<br>';
echo $since_start->y.' years<br>';
echo $since_start->m.' months<br>';
echo $since_start->d.' days<br>';
echo $since_start->h.' hours<br>';
echo $since_start->i.' minutes<br>';
echo $since_start->s.' seconds<br>';

$since_start是一个DateInterval对象。注意，days属性是可用的(因为我们使用了DateTime类的diff方法来生成DateInterval对象)。

上面的代码将输出:

1837天总共5年0个月10天6小时14分2秒

获取总分钟数:

$minutes = $since_start->days * 24 * 60;
$minutes += $since_start->h * 60;
$minutes += $since_start->i;
echo $minutes.' minutes';

这将输出:

2645654分钟

也就是这两个日期之间的实际分钟数。DateTime类将考虑夏令时(取决于时区)，而“旧方法”不会考虑。阅读有关日期和时间的手册http://www.php.net/manual/en/book.datetime.php

以下是答案:

$to_time = strtotime("2008-12-13 10:42:00");
$from_time = strtotime("2008-12-13 10:21:00");
echo round(abs($to_time - $from_time) / 60,2). " minute";

这就是我如何显示“xx次前”在php > 5.2 ..这里是DateTime对象的更多信息

//Usage:
$pubDate = $row['rssfeed']['pubDates']; // e.g. this could be like 'Sun, 10 Nov 2013 14:26:00 GMT'
$diff = ago($pubDate);    // output: 23 hrs ago

// Return the value of time different in "xx times ago" format
function ago($timestamp)
{

    $today = new DateTime(date('y-m-d h:i:s')); // [2]
    //$thatDay = new DateTime('Sun, 10 Nov 2013 14:26:00 GMT');
    $thatDay = new DateTime($timestamp);
    $dt = $today->diff($thatDay);

    if ($dt->y > 0){
        $number = $dt->y;
        $unit = "year";
    } else if ($dt->m > 0) {
        $number = $dt->m;
        $unit = "month";
    } else if ($dt->d > 0) {
        $number = $dt->d;
        $unit = "day";
    } else if ($dt->h > 0) {
        $number = $dt->h;
        $unit = "hour";
    } else if ($dt->i > 0) {
        $number = $dt->i;
        $unit = "minute";
    } else if ($dt->s > 0) {
        $number = $dt->s;
        $unit = "second";
    }
    
    $unit .= $number  > 1 ? "s" : "";
 
    $ret = $number." ".$unit." "."ago";
    return $ret;
}
