PHP＆SQL：从SQL注入保护此查询的最佳方法不使用PDO

Question

我有一个针对mssql数据库运行的查询，我没有使用PDO驱动程序。有没有像我可以使用的准备好的声明？

下面是该查询：

$tsql = "INSERT INTO cplinktable (liferayid, bmsid, autotaskid, waspdb, cpid) VALUES ($liferayid, $bmsid, $autotaskid, '$waspdb', $cpid)"; 

感谢，

微软SQL驱动程序PHP提供预处理语句：

Answer 2

你至少应该逃避值。

PHP Manual - mysql_real_escape_string

Answer 3

尝试用sprint()

$tsql = "INSERT INTO cplinktable (liferayid, bmsid, autotaskid, waspdb, cpid) VALUES (%d, %d, %d, '%s', %d)"; 

$tsql = sprintf($tsql, $liferayid, $bmsid, $autotaskid, $waspdb, $cpid); 
echo $tsql; // you would execute this but printing to the screen to show the query 

Answer 4

$query = sprintf("INSERT INTO cplinktable (liferayid, bmsid, autotaskid, waspdb, cpid) VALUES ('%s','%s','%s','%s','%s')", 
      mysql_real_escape_string($liferavid), 
      mysql_real_escape_string($bmsid), 
      mysql_real_escape_string($autotaskid), 
      mysql_real_escape_string($waspdb), 
      mysql_real_escape_string($cpid)); 

Answer 5

准备语句，它的那么简单，对数字/整数字符串和类型转换期运用mysql_real_escape /双打

(int)$number; //Safe 
(double)$double; //Safe 
mysql_real_escape_string($string); //Safe 

这用在您插入y的每一条数据我们的数据库是安全
