// Instantiate a DateTime 
$datetimefirst = new DateTime('2016-08-24 12:20:00');
$datetimesecond = new DateTime('2016-08-24 12:34:00');
//calculate the difference
$difference = $datetimefirst->diff($datetimesecond);
//format the Output 
echo $difference->format('%Y-%m-%d %H:%i:%s');

reference

The DateTime class:
This class behaves the same as DateTimeImmutable except objects are modified itself when modification methods such as DateTime::modify() are called.

    Welcome to Stack Overflow!

Here is the solution,

<?php

$d1='2016-08-24 12:22:13';
$d2='2016-08-24 12:22:30';
$diff=strtotime($d2)-strtotime($d1);
echo $diff;

?>

For get difference between two date you have to convert it into time stamp first and take difference from there.

$d1='2016-08-24 12:22:13';
$d2='2016-08-24 12:22:30';
$diff=abs(strtotime($d2)-strtotime($d1));

echo "Diff ".date('H',$diff)." hours ".date('i',$diff)." minutes ".date('s',$diff)." Seconds";

here I have used abs() for convert into positive value of difference.
