GET or POST will probably depend on the size of your data : there is a limit on the amout of data you can pass through GET (something like 2000 bytes ; more, depending on the browser).

There is also an other thing to take into account : if you are modifying data, you should use POST ; not GET, which is used to... get... data.

About the format, I would really not go for anything like a custom function doing any kind of stuff like base64 : I would definitly go for JSON, which is a native Javascript notation.

You can for instance have a look at :

• wikipedia
• http://www.json.org/

There are many JS libraries that can generate JSON (probably every JS Framework can ; and there are standlone libraries like this one) ; and since PHP 5.2 there are functions in PHP to encode/decode it (see json_encode and json_decode)
