How can the error handling in the code be enhanced to provide more informative messages to users?

The error handling in the code can be enhanced by implementing custom error messages that provide more information to users about the nature of the error. This can be achieved by using try-catch blocks to catch specific exceptions and then displaying custom error messages based on the type of exception caught.

try {
    // Code that may throw an exception
    $result = 10 / 0;
} catch (DivisionByZeroError $e) {
    echo "Error: Division by zero is not allowed.";
} catch (Throwable $e) {
    echo "An error occurred: " . $e->getMessage();
}
