Photo Gallery in PHP and MySQL

In this article I would like to share with you program that is written by my friend Mr. Dave Marcellana he called his program Photo Gallery. Dave would like to share his work to us to help also other programmers understand how to work with images and text in PHP and MySQL. What does the program do is to allow our user to upload the picture of the picture and text description afterwards we have a combo box which allows us to select which photo album we want to display. In this example we can also populate the data entry from our MySQL table to our web page. I hope the work of my friend Dave we will help you a lot in understanding how to program in PHP and MySQL.

Simple Calculator in Java

In this simple and short article I would like to share with you a simple calculator that I wrote using Java as my programming language what the program will do is to ask the user to enter a simple mathematical expression for example 5 + 6 and then the user will press the enter key and it will display the result of 11. It has four basic math functions addition, subtraction, multiplication and division. My program also ask the user if the user would like to give a different value and change new operator by asking the user do you want to continue. The code is very simple primarily I'm just using a switch case statement to select what operator to be used for computation. I hope you will find my work useful and beneficial in learning how to program using Java as your programming language.

If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

Armstrong Number Checker in PHP

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.
