In this article I would like to share with you a sample program that I wrote in PHP that will accept a number and then it will check if the given number is a palindrome or not a palindrome. I called this program Palindrome of Numbers in PHP. For your information Palindrome means that when we read a word or number forward and backward it is the same for example of words that is palindrome in nature is RADAR, AMA, ANA and for numbers 141, 111, 212, 1441. I hope you will find my work useful in your learning 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.
