How can PHP developers ensure the efficient and secure deletion of data using checkboxes?

To ensure the efficient and secure deletion of data using checkboxes in PHP, developers should first validate the input to prevent any potential security vulnerabilities such as SQL injection attacks. They should also confirm the deletion action with a confirmation prompt to avoid accidental data loss. Finally, developers should handle the deletion process securely by using prepared statements and proper error handling to ensure the operation is executed successfully. 

// Validate input and confirm deletion action
if(isset($_POST['delete']) && !empty($_POST['checkbox'])) {
    $ids = implode(',', array_map('intval', $_POST['checkbox']));
    $confirm = confirmDeletion(); // Function to display confirmation prompt
    if($confirm) {
        $sql = "DELETE FROM table_name WHERE id IN ($ids)";
        $stmt = $pdo->prepare($sql);
        $stmt->execute();
        echo "Data deleted successfully";
    }
}

// HTML form with checkboxes for selecting data to delete
<form method="post">
    <input type="checkbox" name="checkbox[]" value="1"> Item 1
    <input type="checkbox" name="checkbox[]" value="2"> Item 2
    <input type="checkbox" name="checkbox[]" value="3"> Item 3
    <button type="submit" name="delete">Delete</button>
</form>
