Description:
------------
The example reads:

Example #1 mssql_get_last_message() example
<?php
// Connect to MSSQL
mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');

// Make a query that will fail
$query = @mssql_query('SELECT * FROM [php].[dbo].[not-found]');

if(!$query)
{
    // The query has failed, print a nice error message
    // using mssql_get_last_message()
    die('MSSQL error: ' . mssql_get_last_error());
}
?>

The line
    die('MSSQL error: ' . mssql_get_last_error());
should be
    die('MSSQL error: ' . mssql_get_last_message());
