Shouldnt it just be `$diff = floor((strtotime("now") - strtotime("-15 minutes"))/60)`? (You missed the brackets and you devided by 3600 rather than 60) — putvande, Feb 21 '14 at 10:40

First of all you are getting hour diff with division to 3600. 15 minutes evaluates to 0 when floored. Also you are only dividing the second variable not the first with those brackets. this should work:

$diff=floor((strtotime("now") - strtotime("-15 minutes"))/60);
echo $diff;// outputs 15

And the extra brackets, otherwise the it is dividing the -15minutes by 60 – putvande Feb 21 '14 at 10:43
