Which is better

foreach ($_GET as $k => $v){ 
$$k = $v;
} 
or
extract( $_GET );

Depends on the scope of your work but i usually try to avoid both methods. Its usually better to just use the cinventional $var = $_GET['key'] in time you will get to see that fetching all the values in $_GET can be bad. I just try to avoid lazy coding at all costs.

Its not. extract() takes away your control. With manually retrieving it, you pass to your script only the keys you need.
