PHP 4.3.10RC2 - Any change in the way rows are fetched ?

Hi there, I was testing PHP 4.3.10RC2 with a well-tested web application when I saw it failed badly. After a little debug, I have found that the problem comes from this SQL query: SELECT CONCAT(num) AS k FROM user WHERE uid LIKE '%XXXX%' where user is a table with num as the PK and uid as a VARCHAR(128). I expect a result like this one (var_export-like display) of the fetched row (with mysql_fetch_array()): ([0] => 67,[k] => 67) But mysql_fetch_array() gives me: ([0] => ([0] => 67,[k] => 67)) For me, it is a really big problem. I do not have it with PHP 4.3.8. I did not take the time to test with PHP 4.3.9 nor 4.3.10 but I took a look at the documentation web sites, the latest Changelogs and made a search on the mailing lists but found nothing about it. Is this the behaviour expected from PHP 4.3.10 ? Is there a way to have the previous/expected behaviour ? Or is this a bug ? Is this the right mailing-list to find some information about this ?
