What are the advantages and disadvantages of using CSV files to store user data compared to a database like MySQL in PHP?

When storing user data, using a database like MySQL in PHP offers advantages such as better data organization, faster querying, and built-in security features. On the other hand, using CSV files may be simpler for small-scale projects, require less setup, and be easier to manage for non-technical users. However, CSV files lack the robustness and scalability of a database system, making them less suitable for larger applications with complex data requirements. 

// Using MySQL to store user data
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// SQL query to insert user data
$sql = "INSERT INTO users (username, email, password) VALUES ('JohnDoe', 'johndoe@example.com', 'password123')";

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

$conn->close();
