Question

What kind of code is this?

Answer 1

+2 A:

That looks like a serialized string from PHP. You'll need to run unserialize to use it. Reference

Is there an online tool I can use to turn words into these strings?

Oh actually I really don't think this is possible. It happens when I select a category on my blog then save. Then that is what is put into the database. I'm trying to figure out a way to create all the searlized codes for each category to use in a CSV file. I guess maybe impossible as I will need to know the structure of how it is made?

You can unserialize the data, convert it to JSON, make changes and use that tool to serialize it again. Or, before it's serialized, write a little code to add/change something in it.

Reply to comment edit: Then you will need to query the database and run their function against the data being provided. It's likely doable, but without knowing specifics I can only say that you'll have to gather the data, make a version of the function your blog runs so that you can pass it the data and it returns the serialized string, and then save that to a CSV file.

If they're all this simple, they're trivial to construct. Given an input string ("11807" in the example), just wrap it in a serialized string like `a:1:{i:0;s:<encoded_length>:"<encoded>";}` and change the data and the length to the actual values (length of the resulting string value after two base 64 encodes etc).

Okey sounds very tricky. I'm a complete noob. I guess I shall just have to keep doing this manually. All 600 of them :-( lol

Mark 2010-10-06 11:19:09

@mark Au contraire. For each category you have, you construct a string using the template I provided, where you **base 64 encode the category number twice to get a string, and then in the template replace <encoded> with the string, and <encoded_length> with the number of characters in the string**. In PHP, I have no idea how to do it. I'd use Perl. :)

Answer 2

+4 A:

As @Codeacula said, it's PHP serialization at work:

a:1:{i:0;s:12:"TVRFNE1EYz0=";}

translates into: array of one element, containing an integer 0 and a string of 12 characters spelling "TVRFNE1EYz0=". It's quite human-readable.

Now, what "TVRFNE1EYz0=" is is anyone's guess. You should probably look into your application for the meaning of that.

To generate serialized strings, use PHP serialize function. Or, start counting letters in your strings. Or use this.

The actual string data is doubly encoded Base 64. In this case, "TVRFNE1EYz0=" is "11807". :)

bzlm 2010-10-06 11:06:36

Ah, cool. Did not check. :) BTW: double base64, WTF?

Amadan 2010-10-06 11:14:55

Oh, this is so not cool. I'm telling my mother you took my answer and added more words. /upvote

Codeacula 2010-10-06 11:21:22

Lol, here's a backvote. :) I did not intend to detract from your firsthood, just provide more details OP wanted.
