In this article I would like to share with you one of a sample program that I wrote just to learn and practice my skills in PHP programming I called this program Fibonacci Number Series Generator in PHP. What the program will do is to ask the user to enter a number and then our program will generate the fibonacci number series in a given number by our user.
If you have some question please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
People here in the Philipines who wish to contact me can reach me at 09173084360.
Thank you very much and Happy Programming
