Question

I have these values in a database:

|12||3||28||7||54|

My code (see below) return these strings:

Username_12

Username_3

Username_28

How to sort in reverse?

How to get these values:

Username_54

Username_7

Username_28

function display_user_friends($profileuserid,$friends,$base_url,$rewrite,$template_directory,$default_avatar) {
  if(!empty($friends)){
        $x = 0;
        $friends = explode("|",$friends);
        foreach($friends as $friend) {
          if($friend>0 && (strpos($already_displayed,"|$friend|")===false) && ($x < 3) {
              $sql_query = "SELECT username,userid FROM users WHERE userid = $friend && userstatus = 1 LIMIT 1";
              $result = @mysql_query($sql_query);
              if(mysql_num_rows($result))
              {
              while($row = mysql_fetch_array($result))
              {
                $x++;

                $already_displayed.="|$friend|";

                $username = stripslashes($row['username']);
                $userid = $row['userid'];
                $content.="<b>$username</b><br>";
              }                  
            }
          }
        }
  }
  else
    $content = "No friends found.";


  return $content;
}

I think you’re looking for array_reverse().

array array_reverse ( array $array [, bool $preserve_keys = false ] )

Takes an input array and returns a new array with the order of the
elements reversed.
