What is the best practice for handling form submissions with radio buttons in PHP?

When handling form submissions with radio buttons in PHP, it is important to check if the radio button is selected before processing the form data. This can be done by checking if the radio button input is set in the $_POST array. If the radio button is selected, you can then access its value to use in your application logic. 

if(isset($_POST['radio_button'])) {
    $selectedOption = $_POST['radio_button'];
    
    // Process the form data based on the selected radio button option
    // For example, you can use a switch statement to handle different cases
    switch($selectedOption) {
        case 'option1':
            // Handle option 1
            break;
        case 'option2':
            // Handle option 2
            break;
        // Add more cases as needed
    }
}
