Php以H：i：s格式获得时间的差异

Question

How can I get the difference of a time.

Let's say the first time value is this:

00:01:00

and the second one is this:

00:03:00

How can I get the difference with the same format.

Answer 1

Try this one

    $startTime = new DateTime("00:01:00");
    $endTime = new DateTime("00:03:00");

    $interval = $startTime->diff($endTime);
    echo $interval->format('%H:%I:%S');

Outputs:

00:02:00

As you asked you wants it to be in same format.
