Answer 1

How does it differ from inserting non-random values ?
mysqli_query($link, "INSERT INTO yourtable (id, cards) VALUES (NULL, '$cards')");
Or something similar.

Answer 2

Pure (My)SQL solution:
INSERT INTO test( x, y )
SELECT 10*rand(),
10*rand()
FROM information_schema.columns
LIMIT 10;

The easiest way to do what you describe would be as #Martin answered.
However this will probably screw you up later. Ideally you don't want to store a list in a RDBMS field; it defeats the whole purpose of having a database.
If you make a table like
ID, cardPosition, cardID
You can do this:
$insert = $db->prepare("INSERT INTO cardpositions (cardPosition, cardID) VALUES (:cardPosition, :cardID)");
foreach ($cards as $cardPosition=>$card)
{
$insert->execute(array(':cardPosition' => $cardPosition, ':cardID' => $card));
}
OR
The wrong way to do this, but the one you seem to want is:
$cardlist = implode(",",$cards); //now you have a comma separated list without the trailing comma
then you do this if PDO:
$insert = $db->prepare("INSERT INTO cardpositions (cardlist) VALUES (:cardlist)");
$insert->execute(array(':cardlist' => $cardlist));
or this if mysqli:
mysqli_query($link, "INSERT INTO yourtable (cardlist) VALUES ('$cardlist')");
