OKWaveの検索API http://search.okwave.jp/ に対応したPHPクラスを作りました。使い方はかなり簡単で、こんな感じです。 includeするファイルはこんな感じです。

&lt;?php
/*
 * OKWave検索API
 * (c) twk http://nonn-et-twk.net/twk/
 *
 * 使用例:
 * require_once 'OkwaveSearch.class.php';
 * $obj = new OkwaveSearch();
 * $obj-&gt;setPhrase('test');
 * $results = $obj-&gt;getResults();
 * var_dump($results);
 */

これ使ってちょっと開発中です。
