How can the error message displayed in a message box in the browser be effectively addressed in the context of the provided code?

The error message displayed in a message box in the browser can be effectively addressed by properly handling the error within the PHP code. This can be achieved by using try-catch blocks to catch any exceptions that may occur and display a custom error message instead of the default one. By implementing error handling mechanisms, you can provide a more user-friendly experience and prevent sensitive information from being exposed to the end user. 

try {
    // Your code that may throw an exception
} catch (Exception $e) {
    echo "An error occurred. Please try again later.";
}
