note 102297 added to function.rand

Well, i don't know much about php and i try to get my own solutions:

<?php

include('config.php');

$lastid= 'lastid';

$result = mysql_query("SELECT id AS $lastid FROM registered_members ORDER BY id DESC LIMIT 0,1");

while($row = mysql_fetch_array($result))
  {
  $lastid2= $row[$lastid];} 
    
  echo rand(0, $lastid2);
  
?>

This will get the latest value from ID row, once this is done, the rand($min, $max) will work. Any inconviniet? Just need to generate random numbers between the 0 and the latest id entry on the registered_members
