In PHP, what are some recommended best practices for handling user input and database interactions when working with radio inputs?

When working with radio inputs in PHP, it is important to sanitize and validate user input to prevent SQL injection attacks and ensure data integrity. It is recommended to use prepared statements when interacting with the database to securely handle user input. 

// Assuming $conn is your database connection

// Sanitize and validate user input
$selectedOption = filter_input(INPUT_POST, 'radio_input', FILTER_SANITIZE_STRING);

// Prepare a SQL statement using prepared statements
$stmt = $conn->prepare("INSERT INTO table_name (radio_column) VALUES (?)");
$stmt->bind_param("s", $selectedOption);

// Execute the statement
$stmt->execute();

// Close the statement and database connection
$stmt->close();
$conn->close();
