What are the potential security risks of generating and distributing access codes from a CSV file on a website?

Generating and distributing access codes from a CSV file on a website can pose security risks such as exposing sensitive information if the CSV file is accessed by unauthorized users. To mitigate this risk, it is recommended to store the access codes securely in a database and only retrieve and distribute them as needed. 

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

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

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

// Retrieve access codes from database
$sql = "SELECT access_code FROM codes_table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Access Code: " . $row["access_code"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
