Hi, This rfc about replacing json with jsond is under discussion.
https://wiki.php.net/rfc/jsond I have finally done some benchmarks. You can find a link in the RFC. It's been extensively tested for the last few months and there is just one BC that I'm aware of. The new parser accepts only float number that conforms to RFC 7159 . This is also not consistent between decoding float number that are and are not in the array/object ( there are two conversion rules). The following formats are rejected: 1. parsed at the top level: 07, 0xff, .1, -.1 2. parser by JSON_Parser: [1.], [1.e1] I feel that this was a bug in the new parser and we must conform to RFC 7159 ! Cheers Jakub
