LXIX. JSON 関数

導入

この拡張モジュールは、JavaScript Object Notation (JSON) というデータ交換形式を実装したものです。デコード処理は、 Douglas Crockford による JSON_checker を基にしています。

要件

PHP 5.2.0 以降、JSON 拡張モジュールはデフォルトで PHP に組み込まれます。

この PECL 拡張モジュールをインストールする方法は、 マニュアルの PECL 拡張モジュールのインストール という章にあります。 新規リリース・ダウンロード・ソースファイル・管理者情報・CHANGELOG といった関連する情報については、次の場所にあります。 http://pecl.php.net/package/json

目次
json_decode -- JSON 文字列をデコードする
json_encode -- 値を JSON 形式にして返す

although the Json is more widely acceptable serialization/deserialization scheme than WDDX, but the decoding speed with Chinese character in WDDX in PHP is much faster than Json; the same several MB serialized data file can deserialize in only ~80ms and for Json is 800ms, 10 times difference !!!

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)

http://mike.teczno.com/json.html

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