Converting Seconds to HH:MM:SS

I have an integer as a number of seconds. I want to convert that integer into into hours/minutes/seconds like this:

1:45:32

If the number of seconds equates to less than one hour then it should return the string:

45:32

If the number of minutes is less than 10 it should return the string formatted like this:

3:25

And finally if the number of seconds equate to less than 1 minute, it should return the following:

0:04

What is the best way to do this in PHP?

Answer 1

The simpelst approch would be

if($seconds < 3600){
 $format = 'i:s';
}else{
 $format = 'G:i:s';
}

echo date($format, $seconds);

EDIT: this wouldnt fix your minutes < 10 problem. you could handle the minutes by itself. like

$time = ($seconds >= 3600) ? date('G', $seconds).':' : '';
$time .= intval(date('i',$seconds)).':'.date('s', $seconds);
