What is the correct syntax for retrieving radio button values from a form in PHP?

To retrieve radio button values from a form in PHP, you need to check if the radio button was selected and then retrieve its value using the $_POST superglobal. You can do this by checking if the radio button is set in the $_POST array and then accessing its value. Make sure that the radio button inputs in your HTML form have the same name attribute. 

if(isset($_POST['radio_button_name'])){
    $radio_button_value = $_POST['radio_button_name'];
    // Use the $radio_button_value as needed
}
