What are the implications of not all users having JavaScript enabled when using radiobuttons in PHP forms?

When not all users have JavaScript enabled, the radiobuttons in PHP forms may not function as intended, leading to potential errors or incorrect data submission. To ensure that the radiobuttons work properly regardless of JavaScript status, you can use PHP to handle the form submission and processing. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selectedOption = $_POST["radiobutton"];
    
    // Process the selected radiobutton option here
    
    echo "Selected option: " . $selectedOption;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="radio" name="radiobutton" value="option1"> Option 1
    <input type="radio" name="radiobutton" value="option2"> Option 2
    <input type="radio" name="radiobutton" value="option3"> Option 3
    
    <input type="submit" value="Submit">
</form>
