Solr 学习（6） —- Solr的PHP客户端

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 HTMLheader('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 $e)  {    // in production you'd probably log or email this error to an admin        // and then show a special message to the user but for this example        // we're going to show the full exception        die("<html><head><title>SEARCH EXCEPTION</title><body><pre class="brush:php;toolbar:false">{$e->__toString()}
