Question

如果我将序列化数组存储到mysql数据库，我应该在使用serialize函数之前或之后进行清理。或者我甚至需要消毒？

例如：

$details['name'] = mysql_real_escape_string($_POST['name']);
$details['email'] = mysql_real_escape_string($_POST['email']);
$details['phone'] = mysql_real_escape_string($_POST['phone']);

$serializedDetails = serialize($details);

// Do SQL query

或者

$details['name'] = $_POST['name'];
$details['email'] = $_POST['email'];
$details['phone'] = $_POST['phone'];

$serializedDetails = mysql_real_escape_string(serialize($details));

也许在第二个我可以做到：

$serializedDetails = serialize($details);

在处理可能带引号/斜杠的字符串时，

始终使用mysql_real_escape_string。如果不这样做，您将遭到破坏/恶意查询。 serialize()的输出有时会带引号/斜杠，因此您应该使用它。但是，不需要预先序列化数组的每个项目。

$details['name']  = $_POST['name'];
$details['email'] = $_POST['email'];
$details['phone'] = $_POST['phone'];

$serializedDetails = mysql_real_escape_string(serialize($details));

举个例子：序列化“你好”会给你：s:5:"hello"。

$data  = 's:5:"hello"';
$query = 'INSERT INTO tbl (data) VALUES ("' . $data . '")';

// leads to a syntax error from mysql
// (plus it's a huge security hole)
mysql_query($query);

存储序列化数组时进行消毒
