Is it possible to assign fixed values to buttons in PHP and add these values to a variable when clicked?

Yes, it is possible to assign fixed values to buttons in PHP and add these values to a variable when clicked. You can achieve this by creating a form with buttons, each having a specific value assigned to them using the "value" attribute. Then, you can use PHP to retrieve the value of the button that was clicked and add it to a variable. 

<form method="post">
    <button type="submit" name="button1" value="10">Button 1</button>
    <button type="submit" name="button2" value="20">Button 2</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['button1'])) {
        $value = $_POST['button1'];
    } elseif (isset($_POST['button2'])) {
        $value = $_POST['button2'];
    }
    
    // Add the value to a variable
    $total += $value;
    
    echo "Total value: " . $total;
}
?>
