DateTime::diff很酷，但对于这种需要单个单元结果的计算来说很尴尬。手动减去时间戳效果更好:

$date1 = new DateTime('2020-09-01 01:00:00');
$date2 = new DateTime('2021-09-01 14:00:00');
$diff_mins = abs($date1->getTimestamp() - $date2->getTimestamp()) / 60;

时区的另一种方法。

$start_date = new DateTime("2013-12-24 06:00:00",new DateTimeZone('Pacific/Nauru'));
$end_date = new DateTime("2013-12-24 06:45:00", new DateTimeZone('Pacific/Nauru'));
$interval = $start_date->diff($end_date);
$hours   = $interval->format('%h'); 
$minutes = $interval->format('%i');
echo  'Diff. in minutes is: '.($hours * 60 + $minutes);

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";

另一种以分钟为单位计算差异的简单方法。请注意，这是一个在1年范围内计算的样本。详情请点击这里

$origin = new DateTime('2021-02-10 09:46:32');
$target = new DateTime('2021-02-11 09:46:32');
$interval = $origin->diff($target);
echo (($interval->format('%d')*24) + $interval->format('%h'))*60; //1440 (difference in minutes)

试试这个

$now = \Carbon\Carbon::now()->toDateString(); // get current time 
             $a = strtotime("2012-09-21 12:12:22"); 
             $b = strtotime($now);
             $minutes = ceil(($a - $b) / 3600); it will get ceiling value 

我找到了很多解，但我从来没有得到正确的解。但是我已经创建了一些代码来查找分钟，请检查它。

<?php

  $time1 = "23:58";
  $time2 = "01:00";
  $time1 = explode(':',$time1);
  $time2 = explode(':',$time2);
  $hours1 = $time1[0];
  $hours2 = $time2[0];
  $mins1 = $time1[1];
  $mins2 = $time2[1];
  $hours = $hours2 - $hours1;
  $mins = 0;
  if($hours < 0)
  {
    $hours = 24 + $hours;
  }
  if($mins2 >= $mins1) {
        $mins = $mins2 - $mins1;
    }
    else {
      $mins = ($mins2 + 60) - $mins1;
      $hours--;
    }
    if($mins < 9)
    {
      $mins = str_pad($mins, 2, '0', STR_PAD_LEFT);
    }
    if($hours < 9)
    {
      $hours =str_pad($hours, 2, '0', STR_PAD_LEFT);
    }
echo $hours.':'.$mins;
?>

它以小时和分钟为单位输出，例如01小时02分钟，如01:02
