In this article I would like to share with you a sample program in PHP that I wrote that will determine or check what is the day in a given date by our user using PHP as programming language I called this program Date Checker. What our program will do is very simple it will ask the user to enter the month, day and year and then our program will determine what day will fall in the given date by our user. I also added a function that will ask the user if the user want to continue using the program or not. I hope you will find my work useful in your programming assignments and projects.
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.
