What common mistakes do PHP beginners make when transferring their website from local to a hosting provider like Strato?

One common mistake PHP beginners make when transferring their website from local to a hosting provider like Strato is not updating the database connection settings to match the new server credentials. This can lead to database connection errors and the website not functioning properly. To solve this issue, make sure to update the database connection settings in your PHP code to reflect the new server credentials provided by your hosting provider.

// Before transferring your website to a hosting provider like Strato
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydatabase";

// After transferring your website to Strato
$servername = "example.strato.de";
$username = "username";
$password = "password";
$dbname = "mydatabase";

// Update the database connection settings accordingly
$conn = new mysqli($servername, $username, $password, $dbname);

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