What are the differences in error handling between PHP 7.3 and PHP 8.0 that developers should be aware of?

In PHP 8.0, the way errors and exceptions are handled has been improved with the introduction of the "throw" expression, making it easier to handle errors in a more concise and readable way. Developers should be aware of this change and update their error handling mechanisms accordingly. 

try {
    // Code that may throw an exception
    throw new Exception('An error occurred.');
} catch (Exception $e) {
    echo 'Caught exception: ' . $e->getMessage();
}
