Heres the 2 main lines of code:

PHP Code:

$Rec2 = mysql_fetch_array(mysql_query("SELECT Username FROM users WHERE Username != '$_COOKIE[user]'")); 


and

PHP Code:

foreach($Rec2 as $rec)
                    {
                        echo $rec;
                    } 


There are 17 rows in the $Rec2 array, but the foreach statement echo's 1 username 2x, so it currently echos:

bkerrbkerr


Any ideas?

Are you sure your query returns what you think ?
Try to make an echo() of it in the web page, and run it on the server directly, it may be the problem.

As mysql_fetch_array returns an array(obviously), if you use PHP5, the interator interface allows you to go through the array with a simple foreach.
So, if your array contains 17 rows, it would display 17 results...

Try to do a

PHP Code:

$Rec2 = mysql_fetch_array(mysql_query("SELECT Username FROM users WHERE Username != '$_COOKIE[user]'"));
echo"<pre>".print_r($Rec2,1)."</pre>"; 


to dump the structure of the array returned from your query.
Maybe you will spot something

I did that and this is the output of the array

Array
(
    [0] => bkerr
    [Username] => bkerr
)

is there a better way of getting all the usernames from a table?

got it

mysql_fetch_assoc()
