PHP Date difference (calendar control -> conversion in days)

Question

I am currently trying to calculate the date difference with a PHP Script. The days are in a calendar control, while the time is in 2 dropboxes (hour/minute).

You can see my demo form here .

I need the PHP script to return the date in days, using the following formula. If the difference between the dates is > X days and more than 2 hours , then the difference is X+1 days, otherwise it's X Days.

Could anybody provide a solution please?
