Are there any potential security risks associated with using checkboxes in PHP forms?

One potential security risk associated with using checkboxes in PHP forms is that malicious users can manipulate the form data by adding extra checkboxes or changing the values sent to the server. To mitigate this risk, it is important to validate and sanitize the input data on the server-side before processing it.

// Validate and sanitize checkbox input
$checkbox_value = isset($_POST['checkbox_name']) ? 1 : 0;
