How can one ensure compatibility and smooth operation when migrating PHP scripts between different servers?

When migrating PHP scripts between different servers, it is important to ensure compatibility by checking for any server-specific configurations or dependencies. One way to achieve smooth operation is to use server-agnostic code and avoid relying on specific server settings. Additionally, testing the scripts on the new server before fully migrating can help identify and resolve any compatibility issues. 

// Example code snippet to ensure compatibility when migrating PHP scripts between servers

// Check for server-specific configurations or dependencies
if (function_exists('mysqli_connect')) {
    // Server supports MySQLi extension
    // Proceed with MySQLi database connection
} else {
    // Server does not support MySQLi extension
    // Handle the connection using an alternative method
}

// Continue with the rest of the script
