A simple program that I wrote using PHP that will ask the user to give a range from lower bound to upper bound and then our program will generate a series of fibonacci number based on the range that is being specify by our user.
Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
