How can error handling be improved in the provided PHP code snippet to better identify and address issues?

The provided PHP code snippet lacks proper error handling, which can lead to issues going unnoticed or unaddressed. To improve error handling, we can implement try-catch blocks to catch and handle exceptions that may arise during the execution of the code. This will help in identifying and addressing issues more effectively.

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