How can a PHP script be structured to efficiently handle the addition and deletion of topics in a table, as described in the forum thread?

To efficiently handle the addition and deletion of topics in a table, you can create functions in your PHP script to handle these operations. Use prepared statements to prevent SQL injection and ensure data integrity. Additionally, consider implementing error handling to gracefully manage any issues that may arise during the process. 

<?php
// Function to add a new topic to the table
function addTopic($topic) {
    $conn = new mysqli("localhost", "username", "password", "database");

    $stmt = $conn->prepare("INSERT INTO topics (topic_name) VALUES (?)");
    $stmt->bind_param("s", $topic);

    $stmt->execute();

    $stmt->close();
    $conn->close();
}

// Function to delete a topic from the table
function deleteTopic($topic_id) {
    $conn = new mysqli("localhost", "username", "password", "database");

    $stmt = $conn->prepare("DELETE FROM topics WHERE topic_id = ?");
    $stmt->bind_param("i", $topic_id);

    $stmt->execute();

    $stmt->close();
    $conn->close();
}
?>
