Array hall of fame. (hard)

[konnwat]

i got an IRC bot that when you type !hof it brings up the hall of fame. one problem with the hall of fame is if two people have the same "ks" (killing skill) then it only shows one on the hof. heres my code.

[code]
<?PHP
if (stripos($line, ":!hof")>0) {
$hof = '';
$ksreverse = array_flip($ks);
$hofnum = 0;
    for ($i=100; $i>0; $i--) {
if (isset($ksreverse[$i])) {
    $hof[$hofnum] = $ksreverse[$i];
    $hofnum++;
    if ($hofnum == 3) {
break;
    }
}
    }
    fwrite($socket, "PRIVMSG $chan :Hall of Fame: 1st - ".ucwords($hof[0])." || 2nd - ".ucwords($hof[1])." || 3rd - ".ucwords($hof[2])."\r\n");
}
?>[/code]

I tried this one too find if the array has two keys with the same value but theres an error.

[code]
<?PHP
if (stripos($line, ":!hof")>0) {
$hof = '';
$ksreverse = array_flip($ks);
$hofnum = 0;
    for ($i=100; $i>0; $i--) {
if (isset($ksreverse[$i])) {
    $hof[$hofnum] = $ksreverse[$i];
    $hofnum++;
    if ($hofnum == 3) {
break;
    }
}
    }
    $samekscount = array_count_values($ks);
    $ksnicks = array_keys($ks);
    for ($i=0; $i<3; $i) {
        if($samekscount[$ks[$hof[$i]]] > 0) {
            for ($ii=0; $ii<count($ksnicks); $ii++) {
                if($ks[$ksnicks[$ii]] == $samekscount[$ks[$hof[$i]]])
                    if(isset($newhof[$i])) {
                        $newhof[$i+1] = $ksnicks[$ii];
                    } else {
                        $newhof[$i] = $ksnicks[$ii];
                    }
                }
            }
        }
    }
    if(isset($newhof[0])) {
        $hof[0] = $newhof[0];
    }
    if(isset($newhof[1])) {
        $hof[1] = $newhof[1];
    }
    if(isset($newhof[2])) {
        $hof[2] = $newhof[2];
    }
    fwrite($socket, "PRIVMSG $chan :Hall of Fame: 1st - ".ucwords($hof[0])." || 2nd - ".ucwords($hof[1])." || 3rd - ".ucwords($hof[2])."\r\n");
}
?>[/code]

please help, is there any way of asking php to search an array for ALL keys with a certain value?

Take a look at the [url=http://www.php.net/array_keys]array_keys()[/url] function.  When you give it a second parameter, the returned array contains all the keys whose value matches that parameter.
