Are there any common pitfalls to avoid when working with radiobuttons in PHP?

One common pitfall when working with radiobuttons in PHP is not properly handling the form submission. It is important to check if the radiobutton is set before processing the form data. This can be done by using the isset() function to determine if the radiobutton value has been submitted. 

if(isset($_POST['radiobutton'])){
    $radiobuttonValue = $_POST['radiobutton'];
    // Process the radiobutton value here
}
