php functions not updating the mysql database

i have a question that im not able to find a workaround. i have the following :

db("select * from {$game}_stars where event_random = '11'");

$sn_sys = dbr();
if($sn_sys['event_random'] == 11) 

        dbn("update {$game}_stars set event_random = 6 where event_random = '11, metal = '583720', fuel='948372', star_name = 'SuperNova Remnant' where star_id = '$sn_sys[star_id]'");
        dbn("insert into {$game}_news (timestamp, headline, login_id) values (".time().",'The star in <b class=b1>system $sn_sys[star_id]</b> has exploded destroying everything in the system, and leaving a <b class=b1>Supernova Remnant</b> which is extremly rich in metals and fuel.

        #take out non-eps.

        print "<br />Supernova in $sn_sys[star_id] went bang.<br />";
}

this script is set so it inserts a message in the database with the event specs and , of course to run the queries.

Now, only the

insert into {$game}_news

seems to get processed and everything else is not.

here are my db functions

function db($string) {
    global $query;
    $query = mysql_query($string);
}

function dbr() 
{
    global $query;
    $fetched = $query->fields;
    return $fetched;
}
function db2($string) {
    global $query2;
    $query2 = mysql_query($string);
}

function dbr2() 
{
    global $query2;
    $fetched2 = $query2->fields;
    return $fetched2;
}

function dbn

function dbn($string) {
    mysql_query($string);
}

Any ideas on why and any possible solutions? Thank you for reading.

Could you try to change '$ship_sn[ship_id]' with '{$ship_sn[ship_id]}' ?

while ($ship_sn = dbr2()) { - i think it helps. But i think you should rewrite your functions.
