In the provided PHP code snippets, what improvements can be made to ensure better functionality and error handling?

The provided PHP code snippets lack proper error handling, which can lead to unexpected behavior or crashes. To ensure better functionality and error handling, we can use try-catch blocks to catch and handle any potential exceptions that may occur during the execution of the code. 

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