Here is a calculator made in PHP. :)

PHP code:

<form method="get" action=""> Number 1: <input type="text" name="number1" /><br /> Number 2: <input type="text" name="number2" /> <br /> <input type="radio" name="op" value="add" /> Add<br /> <input type="radio" name="op" value="sub" /> Subtract<br /> <input type="radio" name="op" value="mul" /> Multiply<br /> <input type="radio" name="op" value="div" /> Divide<br /> <input type="submit" name="submit" value="Calculate!" /> </form> <?php if ( isset( $_GET['submit'] ) { $number1 = $_GET['number1']; $number2 = $_GET['number2']; if ( $_GET['op'] == "add" ) { $answer = $number1 + $number2; echo ("" . $number1 . " + " . $number2 . " = " . $answer . ""); } if ( $_GET['op'] == "sub" ) { $answer = $number1 - $number2; echo ("" . $number1 . " - " . $number2 . " = " . $answer . ""); } if ( $_GET['op'] == "mul" ) { $answer = $number1 * $number2; echo ("" . $number1 . " * " . $number2 . " = " . $answer . ""); } if ( $_GET['op'] == "div" ) { $answer = $number1 / $number2; echo ("" . $number1 . " / " . $number2 . " = " . $answer . ""); } } ?>
