将对象序列化存储在数据库中后无法反序列化对象 [英] Cannot unserialize object after storing it serialized in database

问题描述

我试图在此处存储一个复杂的对象，并通过序列化在其上运行mysql_real_escape_string的对象并将其插入到mysql数据库中来实现.

I'm trying to store a complex object here and am doing that by serialising the object running a mysql_real_escape_string on it and inserting it into a mysql database.

但是，当我运行SQL查询来检索它时-无论如何，我还是在这里使用Zend框架Zend_DB_Table-当我尝试除斜杠和反序列化时，我没有找回我的对象​​.我已经尝试过反序列化而不去除斜杠，但几乎没有任何作用.

However when I retrieve it running a sql query - I'm using Zend frameworks Zend_DB_Table here but anyway - and when I try to stripslashes and unserialize I dont get my object back. I've tried to just unserialize without stripping slashes and all but nothings working.

更新

这很奇怪.我做了一个简单的页面，只是反序列化了序列化的对象.如果我从数据库中检索序列化的字符串，然后通过另一页对其进行反序列化，则该页面上只有一个unserialize()-它可以完美工作，并且我可以将对象找回来.但是，在具有讽刺意味的是，我正在检索字符串的代码中，我在那里运行完全相同的反序列化选项，它无法正常工作！

This is weird. I made a simple page which just unserializes a serialised object. If I take the serialized string as it is retrieved from the database and unserialize it via this other page which just has an unserialize() on it - it works perfectly and I get my object back. However in the code where ironically I'm retriving the string and I run the exact same unserialize option there ,its not working!

因此，基本上，序列化的字符串没有什么问题-出于某种奇怪的原因，它不会在我的应用程序中反序列化它，但在其他地方反序列化了，这没有任何意义.

So basically there is nothing wrong with the serialized string - for some weird reason it won't unserialize it in my application but it unserializes somewhere else, it makes no sense.

推荐答案

您可能需要先通过base64编码运行它:

You probably need to run it through base64 encoding first:

$safe_string_to_store = base64_encode(serialize($data));

然后将其取回:

$date = unserialize(base64_decode($safe_string_to_store));

尝试一下，让我们知道它是否有效.

Try that and let us know if it works.

(并且不要在其上运行反斜杠-无需这样做)

(and dont run stripslashes on it - there is no need to)
