Are there any potential pitfalls or drawbacks to using an array to store this information in a database?

One potential pitfall of using an array to store information in a database is that arrays are stored in memory, which can lead to performance issues and scalability problems when dealing with a large amount of data. To solve this issue, it is recommended to use a database management system like MySQL to store and retrieve data efficiently.

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

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

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