Question

Heres my function:

function get_r($groupid) {
 if (!empty($groupid)) {     
  $groupid = explode(",", $groupid);
  $rto = array();
  $x=0;
  while (count($groupid,$ustaffid) > $x) {
   $q = mysql_query("SELECT * FROM groups WHERE id='$groupid[$x]'");
   while ($get = mysql_fetch_assoc($q)){
    $rto[] = $get['groupname'];
   }
   $x++;
  }
  $q = mysql_query("SELECT * FROM groups WHERE ustaffid='$ustaffid'");
  $numofgroups = mysql_num_rows($q);
  if ($numofgroups == count($groupid) && count($groupid) > 1) {
   $rto = "All of my groups"; 
  } else {   
   $rto = implode(", ",$rto);
   return $rto;
  }
 }  
}

when I call function I’m using this:

get_r($groupid);

What I’m trying to do is get the variable $rto from my function, I have supplied the function with the $groupid variable. $rto is returning empty.

Thanks for your help!
