How can the error handling in the PHP code be simplified or improved?

The error handling in the PHP code can be simplified by using a try-catch block to catch exceptions and handle errors in a more structured way. This approach helps in centralizing error handling logic and makes the code more readable and maintainable.

try {
    // Code that may throw an exception
    $result = someFunctionThatMayThrowAnException();
    echo $result;
} catch (Exception $e) {
    // Handle the exception
    echo 'An error occurred: ' . $e->getMessage();
}
