該擴展提供了針對Sphinx搜索客戶端開發(fā)庫的綁定. Sphinx是一個獨立的搜索引擎系統(tǒng)，其目的是為其他相關(guān)程序和應(yīng)用提供快速的、規(guī)模可擴展的全文搜索功能. Sphinx有著良好的設(shè)計，可以很方便的與SQL數(shù)據(jù)庫結(jié)合，并使用腳本語言調(diào)用. Sphinx 以及 其客戶端庫 可以從?官方站點獲取，中文用戶也可以從Coreseek獲取支持中文的版本和服務(wù)。

安裝需求：需要PHP5.2.2及以上PHP版本。

安裝步驟請參考：Linux下編譯安裝Sphinx、中文分詞coreseek及PHP的sphinx擴展

安裝過程中，如果?./configure?不能正確找到 libsphinxclient 文件 (例如, 他被安裝在用戶自己定義的目錄中)，使用?./configure --with-sphinx=$PREFIX來制定libsphinxclient的具體位置（$PREFIX是libsphinxclient的安裝位置）。

編譯安裝：

從http://pecl.php.net/package/sphinx下載所需的sphinx擴展源碼安裝包，解壓到指定目錄，進入該目錄。

./configure --with-php-config=/usr/local/php/bin/php-config --with-sphinx=/usr/local/libsphinxclientmakesudo make install二、使用實例

Example #1 基本使用范例

<?php$s = new SphinxClient;$s->setServer('localhost', 6712);$s->setMatchMode(SPH_MATCH_ANY);$s->setMaxQueryTime(3);$result = $s->query('test');var_dump($result);?>

以上例程的輸出類似于：

array(10) { ['error']=> string(0) '' ['warning']=> string(0) '' ['status']=> int(0) ['fields']=> array(3) {[0]=> string(7) 'subject'[1]=> string(4) 'body'[2]=> string(6) 'author' } ['attrs']=> array(0) {} ['matches']=> array(1) {[3]=> array(2) { ['weight']=> int(1) ['attrs']=> array(0) {} } } ['total']=> int(1) ['total_found']=> int(1) ['time']=> float(0) ['words']=> array(1) { ['to']=> array(2) { ['docs']=>int(1) ['hits']=>int(1) } }}三、SphinxClient 類
