这将有助于....

function get_time($date,$nosuffix=''){
    $datetime = new DateTime($date);
    $interval = date_create('now')->diff( $datetime );
    if(empty($nosuffix))$suffix = ( $interval->invert ? ' ago' : '' );
    else $suffix='';
    //return $interval->y;
    if($interval->y >=1)        {$count = date(VDATE, strtotime($date)); $text = '';}
    elseif($interval->m >=1)    {$count = date('M d', strtotime($date)); $text = '';}
    elseif($interval->d >=1)    {$count = $interval->d; $text = 'day';} 
    elseif($interval->h >=1)    {$count = $interval->h; $text = 'hour';}
    elseif($interval->i >=1)    {$count = $interval->i; $text = 'minute';}
    elseif($interval->s ==0)    {$count = 'Just Now'; $text = '';}
    else                        {$count = $interval->s; $text = 'second';}
    if(empty($text)) return '<i class="fa fa-clock-o"></i> '.$count;
    return '<i class="fa fa-clock-o"></i> '.$count.(($count ==1)?(" $text"):(" ${text}s")).' '.$suffix;     
}

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。

<?php
$date1 = time();
sleep(2000);
$date2 = time();
$mins = ($date2 - $date1) / 60;
echo $mins;
?>

减去这些次数，再除以60。

下面是一个计算从2019/02/01 10:23:45经过的时间(以分钟为单位)的例子:

$diff_time=(strtotime(date("Y/m/d H:i:s"))-strtotime("2019/02/01 10:23:45"))/60;

function date_getFullTimeDifference( $start, $end )
{
$uts['start']      =    strtotime( $start );
        $uts['end']        =    strtotime( $end );
        if( $uts['start']!==-1 && $uts['end']!==-1 )
        {
            if( $uts['end'] >= $uts['start'] )
            {
                $diff    =    $uts['end'] - $uts['start'];
                if( $years=intval((floor($diff/31104000))) )
                    $diff = $diff % 31104000;
                if( $months=intval((floor($diff/2592000))) )
                    $diff = $diff % 2592000;
                if( $days=intval((floor($diff/86400))) )
                    $diff = $diff % 86400;
                if( $hours=intval((floor($diff/3600))) )
                    $diff = $diff % 3600;
                if( $minutes=intval((floor($diff/60))) )
                    $diff = $diff % 60;
                $diff    =    intval( $diff );
                return( array('years'=>$years,'months'=>$months,'days'=>$days, 'hours'=>$hours, 'minutes'=>$minutes, 'seconds'=>$diff) );
            }
            else
            {
                echo "Ending date/time is earlier than the start date/time";
            }
        }
        else
        {
            echo "Invalid date/time data detected";
        }
}

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";
