What are some potential pitfalls of creating a separate MySQL database for each user in a PHP application?

One potential pitfall of creating a separate MySQL database for each user in a PHP application is the increased complexity and maintenance overhead. It can lead to scalability issues as the number of users grows, and it may not be the most efficient way to organize data. A better approach would be to use a single database with proper indexing and relationships to manage user data efficiently. 

// Connect to a single MySQL database for user data
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "users";

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

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