How can error handling be improved in the given PHP code snippet?

The given PHP code snippet does not have proper error handling mechanisms in place. To improve error handling, we can use try-catch blocks to catch exceptions and handle them accordingly. This will help in gracefully handling errors and providing meaningful error messages to the users.

try {
    // Code that may throw exceptions
    $result = someFunctionThatMayThrowExceptions();
    echo $result;
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
