Skal have indsat en sætning i en kode, men hvor?

Jeg har følgende script:
#### Open it

    elseif ($action == 10) {
        if ($item_id == 101) {
            for ($i=1;$i<=mt_rand(7,12);$i++) {
                $rand = mt_rand(102,106);
                mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='$rand'");
            }
            $status = "You get some every flavor beans. They have been added into your inventory.";
        }
        if ($item_id == 119) {
            mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='190'");
            $status = "A chocolate frog jumps out from the box.";
            $cardlist = array(4131,4132,4133,4134,4135,4136,4137,4138,4139,721,722,723,724,725,726,727,728,729,721,721,721,721,722,722,723,723,0,0,0,0,0,0,0,0,0);
            $randomcard = $cardlist[array_rand($cardlist)];
            if ($randomcard >= 727 && $randomcard <= 729) {
                if (mt_rand(1,3) == 1) {
                    mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='$randomcard'");
                }
            }
            elseif ($randomcard != 0) {
                mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='$randomcard'");
            }
        }
        if ($item_id == 302) {
            for ($i=1;$i<=mt_rand(7,12);$i++) {
                mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='162'");
            }
            $status = "You get some yellow cherries. They have been added into your inventory.";
        }
        mysql_query("DELETE FROM inventory WHERE object_id='$id'");
    }



Her i skal jeg have indsat:

if ($item_id == 9100) {
            $status = "Did something fall out of the egg?";
            $cardlist = array(4901,4901,4902,4902,4903,4903,4903,4904,4904,4905,4905,4906,4906,4906,4907,4908,4909,135,135,135,135,135,135,135,135,135,727,729,0,0,0,0,0,0,0,0,0);
            $randomcard = $cardlist[array_rand($cardlist)];
            if ($randomcard >= 727 && $randomcard <= 729) {
                if (mt_rand(1,3) == 1) {
                    mysql_query("INSERT INTO inventory SET username='$user_array[username]',item_id='$randomcard'");


Jeg er bare ikke lige en PHP haj, og kan ikke finde ud af, hvor jeg skal indsætte det, og hvor mange } og alt sådan noget. Vil nogen være sød, at vise mig, hvor det skal være?

På forhånd tak
