How can I decode json in PHP 5.1?

Question

json_decode function is not part of PHP 5.1, so I cannot use it. Is there any other function for this version?

Answer 1

I ran into problems with the Services_Json extension on PHP 5.1.3, so I found the following library:

It is under LGPL, and after a very quick look does not seem to eval input.
