jamen HVORFOR?

<?php 

function makepassword($size) {
  $options = \"abcdefghijklmnopqrstuvwxyz1234567890\";
  srand ((double) microtime() * 1000000);
  while(strlen($temp) < $size) $temp .= substr($options,(rand() % strlen($options)),1);
  return $temp;
} 
$passwd = makepassword(8);
$null = \"\";

$connection = mysql_connect(\"localhost\",
\"zyga\",
\"hjort\");
mysql_select_db(\"zyga\", $connection);


$result = mysql_query(\"SELECT password FROM usars WHERE password = \'$passwd\'\") or die(mysql_error());
$row = mysql_fetch_array($result);

while ($passwd = $row[password]) {
$passwd = makepassword(8);
}

mysql_query(\"INSERT INTO usars(password, name, lastname, addy, husnr, city, postnr, telefon, email) VALUES (\'$passwd\', \'$name\', \'$lastname\', \'$addy\', \'$husnr\', \'$city\', \'$post\', \'$telefon\', \'$email\')\");

echo \"dit password er $passwd\";

?>

når jeg så går ind på tingen så siger viser den at den ikke har sat noget password i $passwd
hvad kan der være galt?
