这篇文章主要为大家详细介绍了php实现搜索类封装示例，感兴趣的小伙伴们可以参考一下，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：

1. <?php
2. /**
3. * SoClass.php
4. * 索引与搜索类 */
5. class SoClass {
6. private $_xindex;
7. private $_xsearch;
8. private $_project;
9. public function __construct($project){
10. //载入引导文件
11. require_once 'lib/XS.php';
12. //初始化
13. $xs = new XS($project);
14. $this->_project = $project;
15. $this->_xindex = $xs->index;
16. $this->_xsearch = $xs->search;
17. $this->_xsearch->setCharset('UTF-8');
18. }
19. public function query($keyWord,$row=20,$jnum=0){
20. $xs = new XS($this->_project);
21. $xs->search->setFuzzy();
22. $xs->search->setAutoSynonyms();
23. $xs->search->setQuery($keyWord); //支持同义词搜索，默认打开
24. $xs->search->setLimit($row, $jnum); //设置返回结果最多为 5 条，并跳过前 10 条
25. $docs = $xs->search->search(); //执行搜索，将搜索结果文档保存在 $docs 数组中
26. $count = $xs->search->count(); //获取搜索结果的匹配总数估算值
27. if($count){
28. $data = array();
29. foreach ($docs as $key=>$doc){
30. $data[$key]['pid'] = $doc->pid;
31. $data[$key]['nid'] = $doc->nid;
32. $data[$key]['category'] = $doc->category;
33. $data[$key]['url'] = $doc->url;
34. $data[$key]['name'] = $xs->search->highlight(htmlspecialchars($doc->name));
35. $data[$key]['message'] = $xs->search->highlight(htmlspecialchars($doc->message));
36. }
37. return array('data'=>$data,'count'=>$count);
38. }
39. return array();
40. }
41. public function hotWord($num,$type='lastnum'){
42. return $this->_xsearch->getHotQuery($num,$type);
43. }
44. public function expanded($keyWord){
45. return $this->_xsearch->getExpandedQuery($keyWord);
46. }
47. public function lastCount(){
48. return $this->_xsearch->getLastCount();
49. }
50. public function index($data,$update=0){
51. // 创建文档对象
52. $doc = new XSDocument;
53. $doc->setFields($data);
54. // 添加或更新到索引数据库中
55. if(!$update){
56. $this->_xindex->add($doc);
57. }else{
58. $this->_xindex->update($doc);
59. }
60. }
61. public function delete($idArray){
62. //删除索引(主键删除array('1','2','3'))
63. $this->_xindex->del($idArray);
64. }
65. public function addSynonym($word1,$word2){
66. $this->_xindex->addSynonym($word1,$word2);
67. }
68. public function clearIndex(){
69. $this->_xindex->clean();
70. }
71. }
72. ?>
