为什么我看到两个不同的session_id()值?

I have a little script that works with session id values. When i want to insert the session_id() data to to my db, I see a value of something like 567 in the table. But, when i want to echo the same data using session_id() function, I see a hashed value consisting of 32 chars like d6fc8fe0c82307cc97dd2a0e94c9bb56.

我有一个使用会话id值的小脚本。当我想将session_id()数据插入到我的db时，我看到表中有567的值。但是，当我想使用session_id()函数来响应相同的数据时，我看到一个散列值，包含32个字符，比如d6fc8fe0c82307cc97dd2a0e94c9bb56。

What is the reason of this? Is this some kinda security issue with the PHP ? How can i get the same value?

这是为什么呢?这是PHP的安全问题吗?如何得到相同的值?

Here is the code:

这是代码:

$mysessid = session_id();

$sql = "INSERT into `mytable` (session_id) values('$mysessid')";
// when i use this sql to add the value into the db, i see a value like "7" or "251" etc in the table.

echo $mysessid;
// it outputs a hashed value like "d6fc8fe0c82307cc97dd2a0e94c9bb56"

// two different outputs...

Sounds like your database structure is not formatted for an hex string. What type of field are you using for field session_id?

听起来您的数据库结构没有为十六进制字符串进行格式化。您对字段session_id使用什么类型的字段?
