In what situations is it advisable to opt for virtualization or root servers instead of shared hosting for PHP applications?

Virtualization or root servers are advisable over shared hosting for PHP applications in situations where you need more control over server resources, customization options, and security measures. If your PHP application requires specific software configurations, high traffic volume, or sensitive data handling, virtualization or root servers can provide the necessary flexibility and performance. 

// Example PHP code snippet for connecting to a MySQL database using a root server
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "myDB";

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

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