What are the best practices for handling checkbox values in PHP when deleting records from a database?

When handling checkbox values in PHP for deleting records from a database, it's important to ensure that only the checkboxes that are checked are processed for deletion. This can be achieved by iterating through the checkbox values and checking if they are set before executing the delete query. Using an array to store the checkbox values can help in managing the deletion process efficiently. 

// Assuming checkboxes are named as 'delete[]' in the HTML form
if(isset($_POST['delete'])) {
    foreach($_POST['delete'] as $id) {
        // Sanitize and validate the $id before using it in the delete query
        $id = intval($id); // Assuming IDs are integers
        // Execute the delete query using $id
        // Example: $query = "DELETE FROM table_name WHERE id = $id";
    }
}
