这期内容当中小编将会给大家带来有关Solr的PHP客户端是怎样的,文章内容丰富且以专业的角度为大家分析和叙述,阅读完这篇文章希望大家可以有所收获。
solr查询返回只是xml格式或是json格式,并不像我们平时使用google或百度时的那种漂亮清爽的界面,实际上solr只负责数据的查询和返回,并不负责显示,如果要生成如google那样的界面,还的借助solr的php客户端,通过客户端进行查询后,再通过php代码显示出来。
本文的做法是一台服务器使用tomcat,运行solr,另一台服务器使用apache,负责和用户的交互与显示。
solr的php客户端也有好几个,本文选择了一个简单易用的, php-solr-client ,该项目的地址为 http://code.google.com/p/solr-php-client/,下载后解压放到apache的网站根目录。
下面是一个简单的查询例子:
<?php
// make sure browsers see this page as utf-8 encoded HTML
header('Content-Type: text/html; charset=utf-8');
$limit = 10;
$query = isset($_REQUEST['q']) ? $_REQUEST['q'] : false;
$results = false;
if ($query)
{
// The Apache Solr Client library should be on the include path
// which is usually most easily accomplished by placing in the
// same directory as this script ( . or current directory is a default
// php include path entry in the php.ini)
require_once('Apache/Solr/Service.php');
// create a new solr service instance - host, port, and webapp
// path (all defaults in this example)
$solr = new Apache_Solr_Service('localhost', 8983, '/solr/');
// if magic quotes is enabled then stripslashes will be needed
if (get_magic_quotes_gpc() == 1)
{
$query = stripslashes($query);
}
// in production code you'll always want to use a try /catch for any
// possible exceptions emitted by searching (i.e. connection
// problems or a query parsing error)
try
{
$results = $solr->search($query, 0, $limit);
}
catch (Exception $e)
{
// in production you'd probably log or email this error to an admin
// and then show a special message to the user but for this example
// we're going to show the full exception
die("<html><head><title>SEARCH EXCEPTION</title><body><pre>{$e->__toString()}</pre></body></html>");
}
}
?>
<html>
<head>
<title>PHP Solr Client Example</title>
</head>
<body>
<form accept-charset="utf-8" method="get">
<label for="q">Search:</label>
<input id="q" name="q" type="text" value="<?php echo htmlspecialchars($query, ENT_QUOTES, 'utf-8'); ?>"/>
<input type="submit"/>
</form>
<?php
// display results
if ($results)
{
$total = (int) $results->response->numFound;
$start = min(1, $total);
$end = min($limit, $total);
?>
<div>Results <?php echo $start; ?> - <?php echo $end;?> of <?php echo $total; ?>:</div>
<ol>
<?php
// iterate result documents
foreach ($results->response->docs as $doc)
{
?>
<li>
<table >
<?php
// iterate document fields / values
foreach ($doc as $field => $value)
{
?>
<tr>
<th><?php echo htmlspecialchars($field, ENT_NOQUOTES, 'utf-8'); ?></th>
<td><?php echo htmlspecialchars($value, ENT_NOQUOTES, 'utf-8'); ?></td>
</tr>
<?php
}
?>
</table>
</li>
<?php
}
?>
</ol>
<?php
}
?>
</body>
</html>
进行查询,如输入car ,结果如下
连接solr查询成功,再进行些美工上的优化,就能有像百度一样的查询界面了
