PHP DateInterval format minutes and seconds with leading zero

Question

Trying to generate simple "H:i:s" string from seconds, but can't

example:

$iSecond = 188;
$dtF = new DateTime("@0");
$dtT = new DateTime("@$iSecond");
$size = $dtF->diff($dtT)->format('%H:%i:%s');
echo $size;

should show "00:03:08" , but in fact "00:3:8"

if there is some another date format options to use in format method?

Use capital I and S for your formatting:

$size = $dtF->diff($dtT)->format('%H:%I:%S');

yep, works perfect, just didn't realized that DateTime format is different from date() function – user5267736 Sep 24 '15 at 13:46

They're usually the same but they have a few gotchas to keep you on your toes. :) – John Conde Sep 24 '15 at 13:46

@user5267736, the DateTime format is the same, but when you use diff(), you're returning a DateInterval object, not a DateTime object. – Devon Bessemer Sep 24 '15 at 13:47

John is correct, but your code seems unnecessary, this should be the same:

$iSecond = 188;
$dtT = new DateTime("@$iSecond");
$size = $dtT->format('H:i:s');

There is no reason to create a datetime of @0 and use diff/DateInterval in this code.
