Now fixed in the XML sources. Thanks!

According to reflection, there are both methods AND properties related 
to getting the client info in the mysqli class, but only a property in 
relation to the client version.

The mysqli_driver class only has properties for client info and version.

So you mean they are static methods?

Then the documentation was partial correct, the properties were just missing.

According to php.exe --rc mysqli on PHP 5.3.2-dev (cli) (built: Sep 24 
2009 09:01:58), the methods are NOT static, but normal public 
functions.

Yes, you are right - it appears the mysqli->get_client_info() method is 
there - and what's more it works (according to my test code)! The 
question now I think is - should it be there, as the mysqli-
>get_client_version() method does not seem to be there. So

1) Should these only exist as properties?
2) Should the mysqli->get_client_info() method really be there?
3) If the answer to 2) is yes, what about mysqli->get_client_version() 
method - why is it missing?

I need some clarification on this - there is no point in documenting a 
method that shouldn't be there - on the other hand - if it should be 
there I need to document it and also the get_client_version method.
