连接到MS SQL 2000/的正确PHP配置是什么？

extension=php_mssql.dll

<?php
$server = 'localhost';
$username = 'username';
$password = 'password';
$database = 'database_name';

$connection = mssql_connect($server, $username, $password);

if (!$connection) {
    die('Could not connect: ' . mssql_get_last_message());
}

mssql_select_db($database, $connection);

// Your SQL query here

mssql_close($connection);
?>
