今日試左zend既framework 見到佢入面有Lucene 咁就整左個fulltext search既page。咁就放上黎同大家分享下。
先到zend framework下載 所需的library
先講一講folder的結構
├─index.php
├─search.php
├─library
│ └─Zend
index.php
<?php
mysql_connect(DB_HOSTNAME,DB_USER,DB_PASS);
mysql_select_db(DB_NAME);error_reporting(E_ALL|E_STRICT);

include "Zend/Loader.php";
Zend_Loader::loadClass('Zend_Search_Lucene');
Zend_Loader::loadClass('Zend_Search_Lucene_Document');
Zend_Loader::loadClass('Zend_Search_Lucene_Analysis_Analyzer');
/*

Zend_Search_Lucene_Analysis_Analyzer::setDefault(
new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8());
/*
*↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
* 以上部份 資料是utf8 為編碼的這句為重點。如果你是utf8的話必需加入，否則資料會錯誤
*/

}
$index = new Zend_Search_Lucene('index', true);
$sql = "SELECT `id` , `title`, `description`
