LXXIII. JSON Functions

简介

This extension implements the JavaScript Object Notation (JSON) data-interchange format. The decoding is handled by a parser based on the JSON_checker by Douglas Crockford.

需求

As of PHP 5.2.0, the JSON extension is bundled and compiled into PHP by default.

For those of you who wants to use JSON with PHP4 to process russian KOI8-r text, please read the following article: http://yozhek10nozhek.livejournal.com/5842.html (in russian)



Maybe it is neither completed yet nor professionally-written, but it doesn't aim to be some kind of full-featured manual.



Note, that you must have iconv extension loaded to use it; json extension is not needed, I use Services_JSON (http://pear.php.net/pepr/pepr-proposal-show.php?id=198) implementation.

The JSON function is basically a more widely accepted variation on the WDDX principle:

Two pure-php implementations of the json protocol that might be of use, e.g. for php 4 installs where adding extensions is not an option or because of extra functionality can be found here:



http://sourceforge.net/projects/phpxmlrpc (look for the extras package)

Of course, performance is abysmal compared to the php extension, written in highly optimized C code...
