a function you may find useful

[harmor19]

I have created a function for the private message API but it could be used for other things.
What it does it gets all the users in the usergroupid you specified.
Then you can have it return anything you wish in the user's table.

function users_in_usergroup($var, $select, $seperator)
{
global $db;


$getusers = $db->query_read("SELECT $select FROM " . TABLE_PREFIX . "user WHERE usergroupid ='".intval($var)."' ");
while($user = $db->fetch_array($getusers))
{
$users_in_usergroup .= $user[$select].$seperator." ";
}

return $users_in_usergroup;
}

echo users_in_usergroup('6', 'username', ';');
