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。 require_once 'OkwaveSearch.class.php'; $obj = new OkwaveSearch(); $obj->setPhrase('test'); $results = $obj->getResults(); var_dump($results); includeするファイルはこんな感じです。 <?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->setPhrase('test'); * $results = $obj->getResults(); * var_dump($results); */ // http://alexandre.alapetite.net/doc-alex/domxml-php4-php5/index.en.html if (version_compare(PHP_VERSION,'5','>=')) require_once 'domxml-php4-to-php5.php'; /** * OKWave検索API * * @see "http://search.okwave.jp/" */ class OkwaveSearch { var $reqURL = 'http://search.okwave.jp/search'; var $apiEncoding = 'UTF-8'; var $scriptEncoding = 'Shift_JIS'; /** 単一指定パラメータ */ var $params = array( 'mode' => 'search', ); /** 検索対象 */ var $targets = array(); /** データ取得対象 */ var $takes = array(); function OkwaveSearch(){ } function setScriptEncoding($scriptEncoding){ $this->scriptEncoding = $scriptEncoding; } function setPhrase($phrase){ $this->params['word'] = mb_convert_encoding($phrase, $this->apiEncoding, $this->scriptEncoding); } /** * @param 'keyword' or 'word' */ function setType($type){ $this->params['type'] = $type; } function setStart($start = '0'){ $this->params['start'] = $start; } function setItems($results='10'){ $this->params['items'] = $results; } function setBoolean($value){ $this->params['boolean'] = $value; } function setSort($sort){ $this->params['sort'] = $sort; } function setOrder($order){ $this->params['order'] = $order; } /** * @param String yyyy-MM-dd */ function setBeforeDate($beforeDate){ $this->params['before_date'] = $beforeDate; } /** * @param String yyyy-MM-dd */ function setAfterDate($afterDate){ $this->params['after_date'] = $afterDate; } function setQuestionStatus($quesStat){ $this->params['ques_stat'] = $quesStat; } function setAnswerStatus($ansStat){ $this->params['ans_stat'] = $ansStat; } function setThanksStatus($thankStat){ $this->params['thank_stat'] = $thankStat; } function setRemarkStatus($remarkStat){ $this->params['remark_stat'] = $remarkStat; } /** * @param int or 'all' */ function setCategoryId($c){ $this->params['c'] = $c; } function setTargets($targets = array()){ $this->targets = $targets; } function setTakes($takes = array()){ $this->takes = $takes; } /** * @return array or false */ function getResults(){ if (strlen(@$this->params['word'])==0) return false; $query = $this->buildQuery($this->params, $this->targets, $this->takes); $xml = file_get_contents($this->reqURL . $query); $dom = domxml_open_mem($xml, DOMXML_LOAD_PARSING, $error); if (!$dom) return false; return $this->xml2result($dom); } function buildQuery($params = array(), $targets = array(), $takes = array()){ $q = array(); foreach ($params as $key => $value) $q[] = "$key=$value"; foreach ($targets as $target) $q[] = "target=$target"; foreach ($takes as $take) $q[] = "take=$take"; return count($q) > 0 ?
