What are some common pitfalls when counting and storing values from radio inputs in PHP forms?

One common pitfall when counting and storing values from radio inputs in PHP forms is not properly handling unchecked radio buttons, which can result in missing or incorrect data being stored. To solve this issue, you should check if the radio button is checked before trying to access its value in the PHP code. 

// Example of counting and storing values from radio inputs in PHP forms

// Check if the radio button is checked before accessing its value
if(isset($_POST['radio_input'])) {
    $radio_value = $_POST['radio_input'];
    // Process the radio input value here
} else {
    // Handle the case where the radio button is unchecked
    $radio_value = "No option selected";
}
