How to change second to min or hour

How can I do? like it was 90second left but changes to 1min 30sec left

 

Given the number of seconds left, you can use division and rounding to convert to a whole amount in a larger unit. After that the modulo operator can determine the remaining seconds.

Example:

PHP:

$totalSeconds = 90;

$minutes = floor($totalSeconds / 60); // the divisor is 60 because 60 seconds fit into 1 minute
$seconds = $totalSeconds % 60;

echo $minutes.":".$seconds;
// output: 1:30


A similar approach for hours:

PHP:

$totalSeconds = 3800;

$minutes = floor($totalSeconds / 60);
$seconds = $totalSeconds % 60;

$hours = floor($minutes / 60); // the divisor is still 60 because 60 minutes fit into 1 hour
$minutes = $minutes % 60;

echo $hours.":".$minutes.":".$seconds;
// output: 1:3:20
