The fact that you mention JSON or PHP at all makes it technical. The reader couldn't care less whether GC was implemented in PHP, Javascript or COBOL. It is totally irrelevant for him. Just as whether the server uses AMD or Intel chips. To non-programmers the term JSON is just gobbledegook, not telling them anything useful, and to programmers it would likely not be telling anything new.
