Verify json_decode was successful

json_decode will return null if the json is invalid. Check for it and return original content.

Or you could use this:

That is cool. Too bad it is 5.3+. I'll have have to think of how I want to deal with version specific features.

Oh, huh. So it is, I guess I need to update my own JSON wrapper.

FWIW, you might find it useful. MIT Licensed, as well: http://github.com/OpenFlame/OpenFlame-Framework/blob/64f0e75c8ea28f12d8de66e7d4b6b96747cb4589/src/OfJSON.php

I changed it recently so it detects if json_last_error() is present, and if not it'll just throw an exception of code:
OfJSONException::ERR_JSON_UNKNOWN

The exception classes themselves are in src/OfException.php if you want to use that as well. Feel free to reuse the code with proper author/license notation, if you want.
