In this tutorial, we are going to create Calculator using Dropdown in PHP
. I create this simple program in PHP using the drop-down menu to select a mathematical operator such as Addition, Subtraction, Multiplication, and Division.
Check the live demo, click the button below.
First, we have to create the markup for this program. This source code contains two TextBox where the user enters the desired numeric value and one combo box where they can select in what mathematical operator they have to use.
To execute the calculator, we need to construct the PHP query where the operators can run after hit the calculate button on the web page. Let's create one by one.
Sample Output for Addition
Sample Output for Subtraction
Sample Output for Multiplication
Sample Output for Division
For the complete source code.
Using the source code below, you can use a mathematical operator such as Addition, Subtraction, Multiplication, and Division.
