Bug #45851 mysqli_fetch_object should detect empty column names

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);
$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"

The error message should be clear enough, changing the behavior there creates costs which aren't justified by such a tiny cosmetic improvement.
