What are some best practices for handling radio box selections in PHP?

When handling radio box selections in PHP, it is important to ensure that the selected value is properly validated and sanitized to prevent any security vulnerabilities. One best practice is to use the isset() function to check if the radio box value has been set before processing it. Additionally, using a switch statement can help handle different scenarios based on the selected value. 

if(isset($_POST['radio_box'])) {
    $selected_value = $_POST['radio_box'];

    switch($selected_value) {
        case 'option1':
            // Handle option 1
            break;
        case 'option2':
            // Handle option 2
            break;
        default:
            // Handle default case
            break;
    }
}
