本文為大家分享了php實現搜索類封裝示例，供大家參考，具體內容如下
<?php
/**
* SoClass.php
* 索引與搜索類 */
class SoClass {
private $_xindex;
private $_xsearch;
private $_project;
public function __construct($project){
//載入引導文件
require_once 'lib/XS.php';
//初始化
$xs = new XS($project);
$this->_project = $project;
$this->_xindex = $xs->index;
$this->_xsearch = $xs->search;
$this->_xsearch->setCharset('UTF-8');
}
public function query($keyWord,$row=20,$jnum=0){
$xs = new XS($this->_project);
$xs->search->setFuzzy();
$xs->search->setAutoSynonyms();
$xs->search->setQuery($keyWord); //支持同義詞搜索，默認打開
$xs->search->setLimit($row, $jnum); //設置返回結果最多為 5 條，並跳過前 10 條
$docs = $xs->search->search(); //執行搜索，將搜索結果文檔保存在 $docs 數組中
$count = $xs->search->count(); //獲取搜索結果的匹配總數估算值
if($count){
$data = array();
foreach ($docs as $key=>$doc){
$data[$key]['pid'] = $doc->pid;
$data[$key]['nid'] = $doc->nid;
$data[$key]['category'] = $doc->category;
$data[$key]['url'] = $doc->url;
$data[$key]['name'] = $xs->search->highlight(htmlspecialchars($doc->name));
$data[$key]['message'] = $xs->search->highlight(htmlspecialchars($doc->message));
}
return array('data'=>$data,'count'=>$count);
}
return array();
}
public function hotWord($num,$type='lastnum'){
return $this->_xsearch->getHotQuery($num,$type);
}
public function expanded($keyWord){
return $this->_xsearch->getExpandedQuery($keyWord);
}
public function lastCount(){
return $this->_xsearch->getLastCount();
}
public function index($data,$update=0){
// 創建文檔對象
$doc = new XSDocument;
$doc->setFields($data);
// 添加或更新到索引數據庫中
if(!$update){
$this->_xindex->add($doc);
}else{
$this->_xindex->update($doc);
}
}
public function delete($idArray){
//刪除索引(主鍵刪除array('1','2','3'))
$this->_xindex->del($idArray);
}
public function addSynonym($word1,$word2){
$this->_xindex->addSynonym($word1,$word2);
}
public function clearIndex(){
$this->_xindex->clean();
}
}
?>
