Convert seconds to Hour:Minute:Second

Question

I need to convert seconds to \"Hour:Minute:Second\".

For example: \"685\" converted to \"00:11:25\"

How can I achieve this?

Here is a very clean and short method!

This code avoids as much as possible of the tedious function calls and piece-by-piece string-building, and the big and bulky functions people are making for this.

It produces "1h05m00s" format and uses leading zeroes for minutes and seconds, as long as another non-zero time component precedes them.

And it skips all empty leading components to avoid giving you useless info like "0h00m01s" (instead that will show up as "1s").

Example results: "1s", "1m00s", "19m08s", "1h00m00s", "4h08m39s".

$duration = 1; // values 0 and higher are supported!
$converted = [
    'hours' => floor( $duration / 3600 ),
    'minutes' => floor( ( $duration / 60 ) % 60 ),
    'seconds' => ( $duration % 60 )
];
$result = ltrim( sprintf( '%02dh%02dm%02ds', $converted['hours'], $converted['minutes'], $converted['seconds'] ), '0hm' );
if( $result == 's' ) { $result = '0s'; }

If you want to make the code even shorter (but less readable), you can avoid the $converted array and instead put the values directly in the sprintf() call, as follows:

$duration = 1; // values 0 and higher are supported!
$result = ltrim( sprintf( '%02dh%02dm%02ds', floor( $duration / 3600 ), floor( ( $duration / 60 ) % 60 ), ( $duration % 60 ) ), '0hm' );
if( $result == 's' ) { $result = '0s'; }

Duration must be 0 or higher in both of the code pieces above. Negative durations are not supported. But you can handle negative durations by using the following alternative code instead:

$duration = -493; // negative values are supported!
$wasNegative = FALSE;
if( $duration < 0 ) { $wasNegative = TRUE; $duration = abs( $duration ); }
$converted = [
    'hours' => floor( $duration / 3600 ),
    'minutes' => floor( ( $duration / 60 ) % 60 ),
    'seconds' => ( $duration % 60 )
];
$result = ltrim( sprintf( '%02dh%02dm%02ds', $converted['hours'], $converted['minutes'], $converted['seconds'] ), '0hm' );
if( $result == 's' ) { $result = '0s'; }
if( $wasNegative ) { $result = "-{$result}"; }
// $result is now "-8m13s"
