This doesn't make much sense to me, unless you need the value of $rows
later on...

how about this instead:

if (!$result = mysql_query("..."))
die ("...");

while ($row = mysql_fetch_array($result))
$results[] = $row;

You're defining two additional variables that are totally unneeded.
Of course some pedant is probably going to jump down my throat for
putting assignments in my conditionals...
