$date1 = new DateTime("2011-02-01");
$date2 = new DateTime("2012-01-01");
$duration = $date1->diff($date2);
var_dump($duration);

date('Y-m-d', (strtotime($str_start_date) + round((strtotime($str_end_date) - strtotime($str_start_date)) / 2))';

EDIT:

Missunderstood your question. Though you wanted the date between these? You want the difference in seconds?

round((strtotime($str_end_date) - strtotime($str_start_date)) / 2)

where should i use this? I mean I want to view the result in he 3rd input how can i do this? – user1290487 Mar 24 '12 at 20:55
You wish to generate this when the other 2 values are selected? That'd be a javascript solution, not a php as you tagged it. – Robin Castlin Mar 24 '12 at 21:00
so it will work with javascript. how? – user1290487 Mar 24 '12 at 21:06
I'm sorry, I don't know how exactly you want this. – Robin Castlin Mar 24 '12 at 21:12
basically, start date input then end date input and the third input to display the difference between them. – user1290487 Mar 24 '12 at 21:14
