In this short tutorial I would like to share with you sample program to check whether the given number by the user is an armstrong number of not. What our program will do is to ask the user to enter a number and then the user can select the find armstrong number by click the button. Our sample program will also check if the user has entered number or not by using PHP character validation functions. I hope you will find my work useful in your learning in PHP programming.
If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.
People here in the Philippines who wish to contact me can reach me at my mobile number 09173084360.
