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;
}

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;     
}

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";
        }
}

<?php
$start = strtotime('12:01:00');
$end = strtotime('13:16:00');
$mins = ($end - $start) / 60;
echo $mins;
?>

输出:

75

用未来最大的1减去过去最大的1，然后除以60。

时间是Unix格式的，所以它们只是一个大数字，显示了从格林尼治时间1970年1月1日00:00:00开始的秒数
