you can convert times number of minutes since start of day make comparison easier.

07:00 = 07 * 60 + 00 = 420 call $start  

and

07:25 = 07 * 60 + 25 = 445 call $end 

similarly convert user input hh:mm min above , call them $userstart , $userend. need is:

if($userstart >= $start && $userend <= $end) {   // valid }
