Why is it recommended to use a single database with normalization instead of creating individual databases for each customer in PHP applications?

Using a single database with normalization is recommended over creating individual databases for each customer in PHP applications because it allows for easier management, scalability, and maintenance. With normalization, data redundancy is reduced, ensuring data integrity and consistency across the application. Additionally, it simplifies queries and updates, making the application more efficient and easier to maintain. 

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

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

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