What improvements or modifications can be made to the PHP script for better functionality?

Issue: The PHP script currently does not handle errors or exceptions gracefully, which can lead to unexpected behavior or crashes. To improve functionality, we can implement error handling using try-catch blocks to catch and handle any exceptions that may occur during script execution.

try {
    // Your existing PHP code here
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
