如何将hh:mm:ss转换为分钟

试试这样的东西：

function minutes($time){
$time = explode(':', $time);
return ($time[0]*60) + ($time[1]) + ($time[2]/60);
}

现场演示

$time    = explode(':', $data['Time']);
$minutes = ($time[0] * 60.0 + $time[1] * 1.0);
$avg     = $minutes > 0 ? $data['Kilometers'] / $minutes : 'inf'; // if time stored is 0, then average is infinite.

另一种将时间戳转换为分钟的方法是，

$time    = date('i', strtotime($data['Time']));

这是一个简单的计算使用这个

    $time='01:02:10';
    $timesplit=explode(':',$time);
    $min=($timesplit[0]*60)+($timesplit[1])+($timesplit[2]>30?1:0);
    echo $min.' Min'  // 62 Min

You can use following function 
<?php
function date2min ($hms) {
    $fromTime = strtotime($hms);
    $getMins = round(abs($fromTime) / 60,2);
    return $getMins;
}

$date   = date('H:i:s');  // $data['Time'] your desired time
$myResult = date2min($date);
and then use $myResult value according to your need.
?>

如果hh:mm:ss是一个字符串，您可以尝试这个经过测试的字符串，它可以工作：

 $hour=substr($string, 0,1);// we get the first two values from the hh:mm:ss string
 $hour=(int)$hour;
 $hourtomin=$hour*60;// after we have the hour we multiply by 60 to get the min
 $min=substr($string, 3,4);//now we do a substring 3 to 4 because we want to get only the min, and we don't want to get the : which is in position 2
 $min=(int)$min;
    
 $totalmin=$hourtomin+$min;// we just do a simple sum to calculate all the min
 echo $totalmin;

你可以用非常简单的方法。

$minutes=$item['time_diff'];
$hours =   sprintf('%02d',intdiv($minutes, 60)) .':'. ( sprintf('%02d',$minutes % 60));
return $hours;

输出将09:10

function hourMinute2Minutes($strHourMinute) {
    $from = date('Y-m-d 00:00:00');
    $to = date('Y-m-d '.$strHourMinute.':00');
    $diff = strtotime($to) - strtotime($from);
    $minutes = $diff / 60;
    return (int) $minutes;
}
echo hourMinute2Minutes('01:30'); // returns 90
