#45851 [NEW]: mysqli_fetch_object should detect empty column names

From:             peterbelm at gmail dot com
Operating system: Any
PHP version:      5.2.6

Bug description:  mysqli_fetch_object should detect empty column names

Description:
------------
If a column is select with an empty name like so:

SELECT id as ``...

You get a fatal error "Cannot access empty property". Looking through the
Zend code I found it happens when looking up property info.
Shouldn't mysqli check for empty property names when creating the object,
triggering it's own (more useful) error?

Reproduce code:
---------------
$link = mysqli_connect($host, $user, $pass);
mysqli_select_db($schema);
$result = mysqli_query("select 'test' as ``", $link);
$obj = mysqli_fetch_object($result);

Expected result:
----------------
A fatal error along the lines of "Empty column name in SQL"

Actual result:
--------------
Fatal error: "Cannot access empty property"
