Adding two numbers is a very easy task. Addition of two numbers and result value in the third box.
We use HTML form and PHP script. Use mathematical logic of adding two numbers and convert them into programming.
First of all, create an HTML form. The HTML form contains three input boxes and one button. When a user fills the number in the first two input boxes and clicks on the submit button then he gets the sum of two numbers.
The user gets results on the same page.
In this above HTML form, we use the POST method. With the help of the POST method, we transfer information to the server. In the previous PHP tutorials, we discussed the POST method in PHP and GET method in PHP. With the help of the POST or GET method, we handle the HTML form information.
This information can be added, multiply, subtraction and divide.
Here, we add two numbers in another variable.
