php calculator source code

How can we create a PHP Calculator? By very less coding & following some steps, we can create a basic calculator in PHP. This tutorial is for those people who want to learn PHP & beginner in PHP. If you have good knowledge in PHP you can create this program in less then 10 minutes.

Previously I had shared how to make a calculator with JavaScript? Now at this time, I am sharing the same type of calculator in the PHP platform. Basically, I created this program in PHP If { } statement. The If { } statement of any programming language work like either-or. Know more about PHP If statement

I create this program in PHP & Bootstrap. I used bootstrap because I am lazy little bit, Using bootstrap I saved my almost 2-3 minute. First, I had created a form with method="POST" then I added action with the same name of the program file. I had saved this program named calculator.php So, I had placed action="calculator.php" in the form tag. Example: <form method="post" action="calculator.php">

Then I had created two text input and one option menu using HTML or Bootstrap. Gave the first input name ‘number1‘ and for the second input ‘number2‘. Example: <input name="number1" type="text" /> & gave name for selection section. Example: <select name="operation"> Then gave value for options (i.e. plus, minus ) & submit button. Example: <option value="plus"> & <input name="submit" type="submit" value="Calculate" />
