为数组中的所有元素添加值（php）

Question

I have a query to get an array from a database.

$result = mysqli_query($con,"SELECT `Time_D` from `Schedule` where `Stop` = 1 ");

while ($row = mysqli_fetch_array($result) ) {                         
echo $row['Time_D'] . "<br>";
}

This array ($row) contains a lot of times, if I'm not mistaken.

I now want to add for example 10 minutes to all the elements in the array. How do I do that?

Well, figured it out myself after all.

$result = mysqli_query($con,"SELECT `Time_D` from `Schedule` where `Stop` = 1 ");

//get database result
while ($row = mysqli_fetch_array($result) ) {                         
$rows[] = $row['Time_D']; //store all the times in one array
}
print_r ($rows);

echo "<br>";
$time_difference=600;
$i=0;

while (($i) < (count($rows)) ) {
$rows[$i] = ( strtotime($rows[$i]) ) + ($time_difference); //with timestamps, because, well, php and times...
$rows[$i] = date('H:i:s', ($rows[$i]) ); // back from timestamp to time
$i = $i +1;
}
print_r($rows);
