How can the functionality of marking and deleting table entries with checkboxes be optimized for performance in PHP?

To optimize the functionality of marking and deleting table entries with checkboxes in PHP, we can reduce unnecessary database queries by processing multiple deletions in a single query. This can be achieved by storing the IDs of the selected checkboxes in an array and then using an IN clause in the SQL query to delete all selected entries at once. 

// Assuming $ids is an array containing the IDs of selected checkboxes

// Construct a comma-separated string of IDs
$idString = implode(',', $ids);

// Perform a single query to delete all selected entries
$sql = "DELETE FROM table_name WHERE id IN ($idString)";
$result = mysqli_query($connection, $sql);

if ($result) {
    echo "Selected entries have been deleted successfully.";
} else {
    echo "Error deleting entries: " . mysqli_error($connection);
}
