How to elegantly output the minutes of a specified time?

The output of the current time is also the number of minutes ending with the specified minute.
For example, 7 14:56:21->14:57:00
14:57:21->15:07:00
It feels like it’s not simple enough to write one myself

<code>function get_minutes($dest){
    $start1 =new DateTime();
    $date = $start1 ->format('Y-m-d-H-i-s');
    list($year,$mon,$day,$hour,$min,$sec) = explode('-',$date);
    $start2 = new DateTime($year.'-'.$mon.'-'.$day.' '.$hour.':'.$min);
    $needle = floor($min/10)*10 +$dest;
    $needle = $needle > $min ? $needle : $needle +10;
    $extra = $needle - $min;
    $timestr = '+ '.$extra.' minutes';
    $start2->modify($timestr);
    return $start2->format('Y-m-d H:i:s');
}
echo get_minutes(7);</code>

Let’s analyze the demand first. The required minutes are 7 minutes, 10+7 minutes, 20+7 minutes, 30+7 minutes, 40+7 minutes, 50+7 minutes; the other 57 minutes to the next node is 7 minutes. The difference is 10 minutes.
Because the total number of seconds from 00:00:00 GMT on January 1, 1970 to now.
The first 7 minutes is 420 seconds, and then 600 seconds are added.
The number of seconds that needs to be added is: first divide the current time by 600. If it is less than 420, just use 420 to subtract it. If it is larger, use 600+420 to subtract it.

<code class="php">$time = time();
echo date('Y-m-d H:i:s',$time);
$last = $time%600;
$last = $last<420?420-$last:1020-$last;
echo '<br />';
echo date('Y-m-d H:i:s',$time+$last);</code>

<code>function get_minutes($dest) {
    if ($dest >= 10) {
        throw new Exception('param error!');
    }
    $mitute = date('i');
    $unit   = $mitute % 10;//个位分钟数
    $offset = $dest - $unit;
    if ($dest <= $unit) {
        $offset += 10;
    }
    return date('Y-m-d H:i:00', strtotime('+' . $offset . ' minutes'));
}

echo get_minutes(7);</code>

What a strange requirement...
I think your code is a bit complicated, but the idea is actually very simple.
Just check whether the single digit of the minute is greater than 7. If it is greater than 7, use 17-single digit, otherwise Use 7-single digits. What you calculate is the difference between the next minute ending in 7 and the current minute. Then just add this difference, right?

<code class="php">$date = new DateTime();
$minute = $date->format('i');
$diff_minute = $minute[1] >= 7 ? (17 - $minute[1]) : (7 - $minute[1]);
$date->add(new DateInterval("PT" . $diff_minute . 'M'));
echo $date->format('Y-m-d H:i:s');</code>

Give me an example. For convenience, 7 is hard-coded in it. You can change it according to your needs.

<code><?php 
$dest = 7;

$dest = $dest*60;
$time = time() - $dest;
$time = ceil($time/600)*600+$dest;
echo $time;
echo date("Y-m-d H:i:s",$time);
?></code>
