    die("Could not connect" . mysql_error());
}

echo "Conected sucessfully" . "<br>";

修订后的代码

<?php
    $my_connection = mysql_connect('localhost', 'root', 'password');
    if (!$my_connection)
        die("Could not connect" . mysql_error());
    echo "Conected sucessfully <br/>";
    mysql_select_db('killer');
    mysql_close($my_connection);
    ?>

将for替换为if，应该这样做
