Explode array and set as associative with default values?

Question

0I have this string:

01, 02, 03, 04, 05, 06, 07, 08, 09

and I need to convert it in an associative array with the numbers as keys and the values set to 0

Array(
   "01" => 0,
   "02" => 0,
   etc
)

I've found the function array_walk but if I try to use it: http://phpfiddle.org/main/code/5z2-bar

$string = "01, 02, 03, 04, 05, 06, 07, 08, 09";
$days = explode(",", $string);

$assDays = Array();

function associate($element) 
{
    $assDays[$element] = 0;
}

echo "<pre>";
print_r(array_walk($days, 'associate'));
echo "</pre>";

Doesn't work. I'm sure the problem is that I don't pass the values to the function associate but I don't know how to do.

Use array_fill_keys:

$assDays = array_fill_keys($days, 0);
