Undefined variable: mysql_num_rows in C:webquery.php on line 16

here is my code:

<?php

require_once ‘login.php’;
$db_server = mysql_connect($db_hostname, $db_username, $db_password);

if(!$db_server) die(“UNable to connect to MySQL: ” . mysql_error());

mysql_select_db($db_database)
or die(“Unable to select database: ” . mysql_error());

$query = “Select * FROM classics”;
$result = mysql_query($query);

if(!$result) die(“UNable to connect to MySQL: ” . mysql_error());

$rows = $mysql_num_rows($result); <<<<this is line 16!
for ($j = 0 ; $j < $rows ; ++$j)
{
echo ‘Author: ‘ . mysql_result($result,$j,’author’) . ‘<br />’;
echo ‘Title: ‘ . mysql_result($result,$j,’title’) . ‘<br />’;
echo ‘Category: ‘ . mysql_result($result,$j,’category’) . ‘<br />’;

@NogDogFeb 02.2011 — Delete the "$" on the front of "mysql_num_rows" (it's a function, not a variable).
