You can't use JSON to parse things, JSON is the data format.

You can use a JSON parser and a JSON serializer at both ends (i.e. in client side JS and server side PHP).

http://json.org/ has links to parsers and serializers in various languages near the bottom, they have documentation which usually includes examples.

JSON is a very simple and straight-forward format, so in case your data model is also simple, you could just use plain echo() or printf() statements on your server to generate the JSON output.

You probably mean that you want to encode something on the server side as JSON. Take a look at json_encode: http://php.net/manual/en/function.json-encode.php
