Question

到目前为止我有两个php文件，test.php：

<?php
            include("../config_conn_fordon_db.php");
            include("../config_open_db.php");
            // Fix Special Characters
            mysql_query("SET NAMES 'utf8'") or die(mysql_error()); 
            mysql_query("SET CHARACTER SET 'utf8'") or die(mysql_error());

            $root = realpath($_SERVER["DOCUMENT_ROOT"]);
            set_include_path($root.'/SV/bincgi/zend/library/');
            require_once('/library/Zend/Db/Adapter/Pdo/Mysql.php');
            require_once('/library/Zend/Search/lucene.php');

            $db = Zend_Db::factory('Pdo_Mysql', array(
            'host'     => 'localhost',
            'username' => 'user',
            'password' => 'password',
            'dbname'   => 'fordon_db'
            ));
            $query="SELECT * FROM cars_db";
            $result = $db->fetchAll($query, 2);
            echo $result[0]['headline'];


            $index = Zend_Search_Lucene::create('/hej/test', true);
            $doc = new Zend_Search_Lucene_Document();

            $doc->addField(Zend_Search_Lucene_Field::Keyword('headline', $result[0]['headline']));
            $index->addDocument($doc);
            $index->commit();

?>

AND search.php：

<?php
            include("../config_conn_fordon_db.php");
            include("../config_open_db.php");
            // Fix Special Characters
            mysql_query("SET NAMES 'utf8'") or die(mysql_error()); 
            mysql_query("SET CHARACTER SET 'utf8'") or die(mysql_error());

            $root = realpath($_SERVER["DOCUMENT_ROOT"]);
            set_include_path($root.'/SV/bincgi/zend/library/');
            //require_once('/library/Zend/Db/Adapter/Pdo/Mysql.php');
            require_once('/library/Zend/Search/lucene.php');

            /*$db = Zend_Db::factory('Pdo_Mysql', array(
            'host'     => 'localhost',
            'username' => 'user',
            'password' => 'password',
            'dbname'   => 'fordon_db'
            ));
            $query="SELECT * FROM cars_db";
            $result = $db->fetchAll($query, 2);
            echo $result[0]['headline'];
            */

            $index = Zend_Search_Lucene::open('/hej/test', true);
            //$doc = new Zend_Search_Lucene_Document();
            echo "Index contains {$index->count()} documents.\n";
            $query = "";
            $hits = $index->find($query);
            echo "Search for \"$query\" returned " .count($hits). " hits.\n\n";
            echo "HEADLINE: "; echo $hits->headline;

?>

我这里有两个问题，首先我根本没有得到任何结果。我不确定“标题”的值是否实际插入（或索引）应该是什么，无论如何都要检查它是否已经过它的索引？

其次，我收到此错误消息：

Notice: Trying to get property of non-object in C:\wamp\www\SV\bincgi\zend\search.php on line 30

这是search.php中的最后一行，我回显标题......

我想要做的是从mysql表中获取所有'标题'字段并将它们编入索引以便我以后可以搜索它们，但我现在只开始使用它。

由于

顺便说一下：当我在test.php中回显$ result [0] ['headline']时，我从mysql表字段中得到结果，所以它可以工作到那么远！

Answer 1

$hits = $index->find($query);

返回的值是一个数组;这就是你收到错误信息的原因。

返回的值通常用于以下代码中：

foreach ($hits as $hit) {
    $title    = $hit->title;
    $contents = $hit->contents;
    ...
}

使这个基本搜索功能起作用的帮助很小（Zend Lucene）
