I have a date value with time. (27/4/2014 18:00:00)

In addition to it, I have a string that consists of days/hours/mins. (10/7/0).

In the end, I need to sum the two values making one date.

In this example, the sum of the values is 37/4/2014 28:7:00.

So the desired result would be 8/5/2014 4:7:00. What is the best way to get this result in PHP??
