        // Get Result
        $result = mysql_query( $query );

        // Iterate over Result
        while( $row = mysql_fetch_array($result) )
        {
            // Chop up the Date
            $date = substr($row['added'],0,4) . '-' .
                    substr($row['added'],5,2) . '-' .
                    substr($row['added'],8,2);

            // Add page details to $buffer
            $buffer[] = '<url>' .

    // Output the Buffer to view. Make sure it looks good.
    echo implode( "\r\n", $buffer );

    // Remove the echo above and uncomment below if it looks good.

    // if( ( $xml = fopen( 'sitemap.xml', "w" ) ) !== FALSE )
    // {
    //     fwrite( $xml, implode( "\r\n", $buffer ) );
    // }

Line 13 & 14, you are building a query without giving a condition for it to search for. You need to look at how to compose a query for SQL (look at Select).

Line 20, you are retrieving the row as ARRAY. If you want to retrieve it to use as an ASSOC, you must pass the keyword to your mysql_fetch_array() to indicate that you will also access it as an associated array (i.e. hash).

Line 28, what are you trying to do here? Are you strying to initiate an array, or assigning string to one of array index?

Do you know PHP? Please do not simply copy & paste code/script from online...
