Solr擴展允許你在PHP5中有效的和Apache Solr服務器通話。

Solr擴展快速, 輕量級, 有允許PHP開發(fā)者和Solr服務器實例有效通話的特性豐富的庫。

兼容APache Solr 1.3 和 1.4。

有內置工具添加文檔和更新到solr服務器，還有工具允許你在搜索文檔時構建高級查詢。

需要PHP5.2.11及以上版本。

需要安裝libxml及curl擴展。

Example #1 啟動文件的內容

<?php/*?Solr服務器的主機域名*/define(’SOLR_SERVER_HOSTNAME’,?’solr.example.com’);/*?是否以安全模式運行?*/define(’SOLR_SECURE’,?true);/*?連接到的HTTP端口?*/define(’SOLR_SERVER_PORT’,?((SOLR_SECURE)???8443?:?8983));/*?HTTP?基本認證名?*/define(’SOLR_SERVER_USERNAME’,?’admin’);/*?HTTP?基本認證密碼?*/define(’SOLR_SERVER_PASSWORD’,?’changeit’);/*?HTTP?連接超時?*//*?http數據傳輸操作時有一個最大執(zhí)行時間（秒），默認是30秒?*/define(’SOLR_SERVER_TIMEOUT’,?10);/*?File?name?to?a?PEM-formatted?private?key?+?private?certificate?*/define(’SOLR_SSL_CERT’,?’certs/combo.pem’);/*?File?name?to?a?PEM-formatted?private?certificate?only?*/define(’SOLR_SSL_CERT_ONLY’,?’certs/solr.crt’);/*?File?name?to?a?PEM-formatted?private?key?*/define(’SOLR_SSL_KEY’,?’certs/solr.key’);/*?Password?for?PEM-formatted?private?key?file?*/define(’SOLR_SSL_KEYPASSWORD’,?’StrongAndSecurePassword’);/*?Name?of?file?holding?one?or?more?CA?certificates?to?verify?peer?with*/define(’SOLR_SSL_CAINFO’,?’certs/cacert.crt’);/*?Name?of?directory?holding?multiple?CA?certificates?to?verify?peer?with?*/define(’SOLR_SSL_CAPATH’,?’certs/’);?>

Example #2 添加文檔到索引

<?phpinclude?'bootstrap.php';$options?=?array( ’hostname’?=>?SOLR_SERVER_HOSTNAME, ’login’????=>?SOLR_SERVER_USERNAME, ’password’?=>?SOLR_SERVER_PASSWORD, ’port’?????=>?SOLR_SERVER_PORT,);$client?=?new?SolrClient($options);$doc?=?new?SolrInputDocument();$doc->addField(’id’,?334455);$doc->addField(’cat’,?’Software’);$doc->addField(’cat’,?’Lucene’);$updateResponse?=?$client->addDocument($doc);print_r($updateResponse->getResponse());?>

以上例程的輸出類似于：

SolrObject Object( [responseHeader] => SolrObject Object( [status] => 0 [QTime] => 446))

Example #3 合并一個文檔到另一個文檔

<?phpinclude?'bootstrap.php';$doc?=?new?SolrDocument();$second_doc?=?new?SolrDocument();$doc->addField(’id’,?1123);$doc->features?=?'PHP?Client?Side';$doc->features?=?'Fast?development?cycles';$doc[’cat’]?=?’Software’;$doc[’cat’]?=?’Custom?Search’;$doc->cat???=?’Information?Technology’;$second_doc->addField(’cat’,?’Lucene?Search’);$second_doc->merge($doc,?true);print_r($second_doc->toArray());?>

以上例程的輸出類似于：

Array( [document_boost] => 0 [field_count] => 3 [fields] => Array( [0] => SolrDocumentField Object( [name] => cat [boost] => 0 [values] => Array( [0] => Software [1] => Custom Search [2] => Information Technology)) [1] => SolrDocumentField Object( [name] => id [boost] => 0 [values] => Array( [0] => 1123)) [2] => SolrDocumentField Object( [name] => features [boost] => 0 [values] => Array( [0] => PHP Client Side [1] => Fast development cycles))))

以上例程的輸出類似于：

SolrObject Object( [responseHeader] => SolrObject Object( [status] => 0 [QTime] => 1 [params] => SolrObject Object( [wt] => xml [rows] => 50 [start] => 0 [indent] => on [q] => lucene [fl] => cat,features,id,timestamp [version] => 2.2)) [response] => SolrObject Object( [numFound] => 3 [start] => 0 [docs] => Array( [0] => SolrObject Object( [cat] => Array( [0] => Software [1] => Lucene) [id] => 334456) [1] => SolrObject Object( [cat] => Array( [0] => Software [1] => Lucene) [id] => 334455) [2] => SolrObject Object( [cat] => Array( [0] => software [1] => search) [features] => Array( [0] => Advanced Full-Text Search Capabilities using Lucene [1] => Optimized for High Volume Web Traffic [2] => Standards Based Open Interfaces - XML and HTTP [3] => Comprehensive HTML Administration Interfaces [4] => Scalability - Efficient Replication to other Solr Search Servers [5] => Flexible and Adaptable with XML configuration and Schema [6] => Good unicode support: héllo (hello with an accent over the e)) [id] => SOLR1000 [timestamp] => 2009-09-04T20:38:55.906))))
