Pascal Triangle in PHP

In this short tutorial I will show you how to create a Pascal Triangle Checker in PHP. What is program will do is very simple it will ask the user to enter a number and then our program will generate the corresponding Pascal Triangle Numbers based on the given number by our user.
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.

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.

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

Floyd's Triangle Maker

In this short article I would like to share with you a sample program that I wrote using PHP as our programming language I called this program Floyd's Triangle Maker what this program will do is to ask the user to enter a number and then it will generate the floyd's triangle on our screen. To give you some insights floyd's triangle was developed by an american computer scientist and mathematician named Robert Floyd. 

According to Wikipedia Floyd's Triangle is a right-angled triangular array of natural numbers, used in computer science education. It is defined by filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner.

1
2    3
4    5     6
7     8     9  10
11  12  13  14 15

Sample of Floyd's Triangle

Calculator Using Radio Buttons in PHP

One of the most enjoying past time that I would like to spend is to write a program it becomes one of my favorite hobbies during my college days. In this article I would like to share with you one of the most common programming problems in PHP how to write a simple calculator using radio buttons in PHP. Some of us think this kind of problem is very simple yes they are for some people who has already learned some experience in PHP programming but for some that are new in PHP problem it can gives us some headache if you don't how to figure it out. Our program will ask the user to enter two number in our text field and then our program will provide four radio buttons addition, subtraction, multiplication and division. Once the user select for example addition and click the solve button it will display the sum of the two numbers. I also added a clear button that enables the user to clear the text field and allows them to enter new values. 

The challenge that I face in writing this program is that I want to keep or retain the value of my selection radio button for example the addition radio button I want to retain its value after i click the solve button. In this program you will know how to accomplish such task with each. I have a great time writing this program I hope you will find my work useful in your quest in learning PHP programming.

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