Finding Referers

[1Unreal]

Im trying to make something which will show what users a user has refered to the site. Im using this code to do it.

PHP Code:

$query = $db->query_read("SELECT `username` FROM `user` WHERE `referrerid` = $id");
$results = $db->fetch_array($query);

ob_start();
   print_r($results);
   $referers = ob_get_contents();
ob_end_clean(); 


The problem is that this only fetches 1 result. I need to get them all.

Place the fetch_array() call into a while loop. Examples can be found in most vBulletin files.

Thank you.

This is my final code if anyone else was curious

PHP Code:

$query = $db->query_read("SELECT `username` FROM `user` WHERE `referrerid` = $id");
while($results = $db->fetch_array($query)){
    $referers .= $results[username];
}
