how to count no. of hours and minutes in two set of time. having a start time to end time.
ex:


1st time : 8:00 to 17:00
2nd time : 9:00 to 18:00
answer : 6hrs <- total number of time

(-) number of hours
(|) start/end

|--------| = 8hrs
|--------| = 8hrs

using only php script. i want to create a four text box, in first two box i want to input a start time and 2nd is end time, for the third one is to input another start time and end time for the last textbox. then a submit button.

when all box have a value, submit the form and show how many hour(s) or minutes the two time have same time. like you will see in my drawing.... hehehe :P
