i think the title is self-explanatory, i work with easyPHP 1.7, which has the php version 4.3.3, which by itself doesn't include support for json, so i found php-json on the web but don't know how to set it up. so can someone help. thanks.
I don't really know easyPHP but I'd suggest you upgrade to something that comes with a more recent PHP-distribution.
On the other hand: before json-support was included in PHP 5.2 I used the PEAR-package Services_JSON. You can install this via PEAR, or just include the one JSON.php file that you can download. Good news is, is that it supports PHP 4.3.
The JSON module for PHP 4.3 can be found in PECL. Unfortunately for you, the packages are provided in a form of a source code, so you have to compile them manually and this is a quite serious problem on Windows. There is another service, pecl4win with binary DLL-s, but it seems to be down now.
I'd suggest you to update PHP to some newer version, because PHP4 is neither supported nor developed and the same is with PHP-JSON for PHP 4.3. Note that the module is going to be a part of PHP core since 5.3.0 version.
