Printing to a formatting string like this seems a bit odd - you're just duplicating the message. Can you do a variable assignment instead?

You shouldn't initialize these values twice - errpos is set to 0 above, and errcode is set to PHP_JSON_ERROR_NONE which is also 0, so these two lines can just be removed

Working POC giving a better error message when the
json_last_error_msgfunction is called (only for this function).Adding near character %d to a json related error message.
Putting aside my bad C coding skill, I would like to know your opinions on this PR, and kindly ask for reviews in order to improve it.
Thx in advance.
(@bukka I know you have been working on a new parser, but ... until that reaches the surface, could we go this way? (with the proper adjustments for sure)
