The date and time format I have is:

Example 1:

$dateTime = 2016-09-08 21:00; //(year-month-day hour:minute)
$interval = 04:00; //(hour:minute)
$outputShouldBe = 2016-09-09 01:00;

Example 2:

$dateTime = 2016-09-08 21:00; //(year-month-day hour:minute)
$interval = 01:40; //(hour:minute)
$outputShouldBe = 2016-09-08 22:40;

</div>

Hey you can try with strtotime and date function

$dateTime = '2016-09-08 21:00';
echo date( "Y-m-d h:i", strtotime( "2016-09-08 21:00 +4 hours" ) ); 
echo date( "Y-m-d H:i", strtotime( "2016-09-08 21:00 +1 hours 40 minutes" ) );
