It shouldn't matter, but try moving the global *AFTER* the extract().
Meanwhile, I think you should probably report this at http://bugs.php.net
Seems pretty broken to this naive user...
(Who likes the idea of extract, but can never remember the darn function
name when I need it...)

Subject: [PHP] inner workings of extract
> Hi all,

> I've recently discovered the extract function (thanks to the poster

> I'm having a problem though. 99 times out of 100 when someone thinks

> $name = $row["name"];
> nextone();
> /*this works fine, but if i have extract($row) and comment out
