ARRAAY ERROR please help

[Anon]

Hello,

Can anyone please help me if an error i encounter which is

Warning: shuffle() expects parameter 1 to be array, null given in /home/wwwadcl/public_html/banner/inc/showbanner/getbanner.inc on line 12

Warning: shuffle() expects parameter 1 to be array, null given in /home/wwwadcl/public_html/banner/inc/showbanner/getbanner.inc on line 14

the script is:

while ($banner = mysql_fetch_array($result_get_banner)){
$bid[] = "$banner[user_login]"; }
$ip = getenv ("REMOTE_ADDR");
srand ((float)microtime()1000000);
shuffle($bid); // LINE 12
srand ((float)microtime()1000000);
shuffle($bid); //LINE 14

$id = "$bid[0]";
$id2 = "$bid[1]";

I'm not too sure but try changing,

$bid[]="$banner[user_login]";

to

$bid[] = $banner[user_login];

see if that makes a difference.

It also won't work if the query doesn't return any results.

what is it exactly that you are trying to do, and what do you want it to do if there are no results in your query??
