[英]How to sanitize data in php in order to avoid SQL injection?
I already used the PDO: 我已经使用了PDO:
$stmt = $aPDO->prepare("INSERT INTO ".$this->getM_oUser()->getM_sTableName()." (email, hash_pw, hash_key) VALUES (:email, :hash_pw, :hash_key)");
$stmt->bindValue(':email', $this->getM_oUser()->getM_sEmail());
$stmt->bindValue(':hash_pw', $this->getM_oUser()->getM_sHash_pw());
$stmt->bindValue(':hash_key', $this->getM_oUser()->getM_sHash_Key());
$stmt->execute();
Should I also use mysql_real_escape_string() to handle the user input string? 我是否还应该使用mysql_real_escape_string()处理用户输入的字符串? Thank you.
谢谢。
Using prepared statements with bound parameters is enough. 使用带有绑定参数的预备语句就足够了。 You don't need to use
mysql_real_escape_string
(and you probably could not even if you wanted -- you 'd need a MySql connection resource in hand to do it). 您不需要使用
mysql_real_escape_string
(即使您愿意也可能无法使用-您需要手头的MySql连接资源)。
I'd do something like that to exclude a lot of useless characters from your table name: 我会做类似的事情来从表名中排除很多无用的字符:
$tableName = '`' . preg_replace('`[^-a-zA-Z0-9_]`', $this->getM_oUser()->getM_sTableName()).'`';
$stmt = $aPDO->prepare("INSERT INTO ".$tableName." (email, hash_pw, hash_key) VALUES (:email, :hash_pw, :hash_key)");
