<b>Answer: </b>
<?php
if(isset($_POST['sum1']) && isset($_POST['sum2']) && isset($_POST['calculate']))
{
$sum1 = strip_tags($_POST['sum1']);
$sum2 = strip_tags($_POST['sum2']);
$task = $_POST['calculate'];
if(!is_numeric($sum1) || !is_numeric($sum2))
{
echo 'You did not enter anything.'; //Stating that the user hit submit without entering a value.
}
else
{
switch($task)
{
case 'add':
echo $sum1 + $sum2;
break;
case 'multiply':
echo $sum1 * $sum2;
break;
case 'subtract':
echo $sum1 - $sum2;
break;
case 'divide':
echo $sum1 / $sum2;
break;
default:
echo 'OoOops!';
break;
}
}
}
