What are the advantages and disadvantages of basing a guestbook on text files versus a MySQL database?

When deciding whether to base a guestbook on text files or a MySQL database, it's important to consider the advantages and disadvantages of each option. Using text files for a guestbook can be simpler and more lightweight, but it may be less efficient for searching and managing large amounts of data. On the other hand, using a MySQL database allows for easier querying and organizing of data, but it may require more resources and technical knowledge to set up and maintain. 

// Sample code snippet for using a MySQL database for a guestbook

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "guestbook";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert new entry into guestbook table
$name = "John";
$message = "Hello, world!";
$sql = "INSERT INTO entries (name, message) VALUES ('$name', '$message')";

if ($conn->query($sql) === TRUE) {
    echo "New entry added successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// Close connection
$conn->close();
