Carbon could also be a nice way to go.

From their website:

A simple PHP API extension for DateTime. http://carbon.nesbot.com/

Example:

use Carbon\Carbon;

//...

$day1 = Carbon::createFromFormat('Y-m-d H:i:s', '2006-04-12 12:30:00');
$day2 = Carbon::createFromFormat('Y-m-d H:i:s', '2006-04-14 11:30:00');

echo $day1->diffInHours($day2); // 47

//...

Carbon extends the DateTime class to inherit methods including diff(). It adds nice sugars like diffInHours, diffInMintutes, diffInSeconds e.t.c.
