SQL注入绕过mysql_real_escape_string（）

问题：

Is there an SQL injection possibility even when using mysql_real_escape_string() function? 即使使用mysql_real_escape_string()函数，也有可能进行SQL注入吗？

Consider this sample situation. 考虑此示例情况。 SQL is constructed in PHP like this: SQL是用PHP构造的，如下所示：

$login = mysql_real_escape_string(GetFromPost('login'));
$password = mysql_real_escape_string(GetFromPost('password'));

$sql = "SELECT * FROM table WHERE login='$login' AND password='$password'";

I have heard numerous people say to me that code like that is still dangerous and possible to hack even with mysql_real_escape_string() function used. 我听过很多人对我说，即使使用mysql_real_escape_string()函数，这样的代码仍然很危险，甚至有可能被破解。 But I cannot think of any possible exploit? 但是我想不出任何可能的利用方式？

Classic injections like this: 像这样的经典注射：

aaa' OR 1=1 --

do not work. 不工作。

Do you know of any possible injection that would get through the PHP code above? 您是否知道上面的PHP代码会进行任何可能的注入？
