本文为大家分享了php实现搜索类封装示例，供大家参考，具体内容如下
<?php
/**
* soclass.php
* 索引与搜索类 */
class soclass {
private $_xindex;
private $_xsearch;
private $_project;
public function __construct($project){
//载入引导文件
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); //支持同义词搜索，默认打开
$xs->search->setlimit($row, $jnum); //设置返回结果最多为 5 条，并跳过前 10 条
$docs = $xs->search->search(); //执行搜索，将搜索结果文档保存在 $docs 数组中
$count = $xs->search->count(); //获取搜索结果的匹配总数估算值
if($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){
// 创建文档对象
$doc = new xsdocument;
$doc->setfields($data);
// 添加或更新到索引数据库中
if(!$update){
$this->_xindex->add($doc);
}else{
$this->_xindex->update($doc);
}
}
public function delete($idarray){
//删除索引(主键删除array('1','2','3'))
$this->_xindex->del($idarray);
}
public function addsynonym($word1,$word2){
$this->_xindex->addsynonym($word1,$word2);
}
public function clearindex(){
$this->_xindex->clean();
}
}
?>
