Bug - I'll modify mysqi_info.phpt to cover this detail.

Interesting question and good point. In real life only few people might
notice the difference and cast the return value to string, but good
question...

Please don't commit the change. I wonder if there are more such tiny
differences. For example, I wonder if my mysqli_info.phpt test is
correct. Let me check in more detail first before we change anything.

Hi Johannes/Ulf

Whereas the documentation says "empty string" for each string property,
i guess that could be modified the macro responsible for that.

What do you think? :)

Description:
------------
$mysqli->info is NULL instead of empty string for "not supported
situations" (i.e. queries other than multi-row INSERT, LOAD, ALTER,
UPDATE)  The procedural mysqli_info() does return the empty string, as
documented.


Reproduce code:
---------------
Query:  'INSERT INTO t (id) VALUES (1),(2),(3)'
mysqli_info():  'Records: 3  Duplicates: 0  Warnings: 0'
$mysqli->info:  'Records: 3  Duplicates: 0  Warnings: 0'

Query:  'INSERT INTO t (id) VALUES (9)'
mysqli_info():  ''
$mysqli->info:  NULL


Expected result:
----------------
(see above)

Actual result:
--------------
the object oriented property $mysqli->info should be the empty string
after "not supported situations", e.g. a single-row insert.
