php - Converting Time From HH:MM:SS Format That Has A Dot To Seconds

Question

I have this kind of string:

$duration = "00:20:55.60000";

It was extracted from a video using ffmpeg. I need to convert it to seconds.

I had tried this: strtotime("1970-01-01 $duration UTC"); (I get it from here) but it's not working. May be because it is containing dot at the seconds part.

Is there a way to convert that string to seconds?

Answer 1

$duration = "00:20:55.60000";
echo date('H:i:s', strtotime($duration));

Answer 2

Try this:

$duration = "00:20:55.60000";
echo time(strtotime($duration));
// returns : 1485346959

Or

echo date('H:i:s', strtotime($duration));
// returns: 00:20:55

Working Code

Answer 3

just use DateTime class.

$now = '00:20:55.60000';
$timevalue = new DateTime($now);
$onlytime = $timevalue->format('H:i:s');
echo $onlytime ;
