What steps can be taken to troubleshoot and resolve broken links and functionality on a PHP website after a server move?

Broken links and functionality on a PHP website after a server move can be resolved by checking and updating any hardcoded URLs in the code to reflect the new server address. Additionally, ensuring that all file paths are correct and that any database connections are updated with the new server credentials can help resolve issues.

// Update hardcoded URLs in the code
define('BASE_URL', 'http://newserver.com/');
// Update file paths
define('UPLOAD_PATH', '/var/www/html/uploads/');
// Update database connection details
$servername = "newserver.com";
$username = "new_username";
$password = "new_password";
$dbname = "new_database";

// Rest of the code to establish database connection and perform queries
