How can radio buttons be processed and evaluated in PHP code?

To process and evaluate radio buttons in PHP, you can use the $_POST superglobal array to access the value selected by the user. Each radio button should have a unique name attribute, and when the form is submitted, the selected value can be retrieved using $_POST['name_of_radio_button']. You can then perform any necessary processing or evaluation based on the selected value. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selected_option = $_POST['radio_button_name'];
    
    // Process or evaluate the selected option
    if ($selected_option == 'option1') {
        echo "Option 1 was selected";
    } elseif ($selected_option == 'option2') {
        echo "Option 2 was selected";
    } else {
        echo "No option selected";
    }
}
?>

<form method="post">
    <input type="radio" name="radio_button_name" value="option1">Option 1
    <input type="radio" name="radio_button_name" value="option2">Option 2
    <input type="submit" value="Submit">
</form>
