• How to calculate the difference between two dates using PHP? 32 answers

I have two time values as follows

$start = '13:00:00';
$end = '21:00:00';

I want calculate the difference between these two time values, I want difference value in format like 00:00:00 (here result would be 08:00:00)

I am using below code to calculate difference

$time = date( "h:i:s", strtotime($end) - strtotime($start));

but it gives me result as 01:30:00

please help if anyone have any idea, i do not want to use DateTime class

In my opinion it is not duplicate, if it is tell me the answer if your can find in duplicate question

Try with this code :

$time1 = strtotime('13:00:00');
$time2 = strtotime('21:00:00');
$diff = $time2 - $time1;
echo 'Difference: '.date('H:i:s', $diff);
