What are the advantages and disadvantages of using a CSV file versus MySQL/Mysqli for storing comments and ratings?

When storing comments and ratings, using MySQL/Mysqli offers advantages such as better data organization, faster querying, and built-in security features. However, using a CSV file may be simpler for smaller projects or when database setup is not feasible. The disadvantages of using a CSV file include slower performance with large datasets, limited querying capabilities, and potential security risks if not properly managed. 

// Example PHP code snippet using MySQL/Mysqli to store comments and ratings

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

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

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

// Insert a new comment and rating into the database
$comment = "This is a great product!";
$rating = 5;

$sql = "INSERT INTO comments_ratings (comment, rating) VALUES ('$comment', $rating)";

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

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