How can button inputs be processed in PHP forms alongside text inputs for calculations?

To process button inputs in PHP forms alongside text inputs for calculations, you can use the isset() function to check if the button has been clicked. If the button is clicked, you can then retrieve the values from the text inputs and perform the necessary calculations. Make sure to name your button input and text inputs appropriately to differentiate them in the form submission. 

<?php
if(isset($_POST['calculate'])) {
    $num1 = $_POST['num1'];
    $num2 = $_POST['num2'];
    
    $result = $num1 + $num2; // Perform calculation
    
    echo "Result: " . $result;
}
?>

<form method="post">
    <input type="text" name="num1" placeholder="Enter number 1">
    <input type="text" name="num2" placeholder="Enter number 2">
    <input type="submit" name="calculate" value="Calculate">
</form>
