What are the potential pitfalls of using cookies to store checkbox selections in PHP?

Potential pitfalls of using cookies to store checkbox selections in PHP include security risks such as cookie tampering or theft, limited storage capacity, and potential conflicts with user privacy preferences. To mitigate these risks, it is recommended to use server-side sessions or database storage for sensitive data instead of relying solely on cookies. 

// Example of using server-side sessions to store checkbox selections

session_start();

// Check if a checkbox is selected
if(isset($_POST['checkbox_name'])) {
    $_SESSION['checkbox_selection'] = $_POST['checkbox_name'];
}

// Retrieve checkbox selection
if(isset($_SESSION['checkbox_selection'])) {
    $checkbox_selection = $_SESSION['checkbox_selection'];
} else {
    $checkbox_selection = '';
}
