How can PHP developers ensure data security and integrity when migrating a PHP script to a new server with a different database setup?

When migrating a PHP script to a new server with a different database setup, PHP developers can ensure data security and integrity by updating the database connection details in the script to match the new server configuration. It is important to securely store database credentials and avoid hardcoding them in the script. Additionally, developers should test the migration thoroughly to ensure that data is transferred accurately and securely. 

<?php
// Update database connection details for the new server
$servername = "new_server";
$username = "new_username";
$password = "new_password";
$dbname = "new_database";

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

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