PHP读取sphinx实例

阅读原文：http://yzswyl.cn/blread-1611.html

1.未采用mysql二进制网络协议的代码：

//检查sphinx是否能连接，不能重试两次，能则连接,不用mysql协议,仅供参考

function checkSphinxNoMysql() {

    $flag = true;

    $retries = 0;

    while ( $flag && $retries < 2 ) {

        $s = new SphinxClient ();

        $s->setServer ( $_ENV ['db_host'], $_ENV ['current_sphinx_port'] );

        if (! $s->open ()) {

            //此处为如果连接不上就更改配置文件，根据项目需要来写

            //global $configDefault;

            //updateConfig ( $configDefault );

            $retries ++;

        } else {

              $flag = false;

            break;

        }

    }

    return $s;

    if ($retries >= 2) {

        //sendemail or not

        return false;

    }

}

  

$order_column = 'id DESC,time DESC';//排序规则

//$s = checkSphinx ();

$s = new SphinxClient ();

$s->setServer ( 'sphinx_host', 'sphinx_port');

//以上两句代码亦可使用$s = checkSphinx ();来代替

$indexname = "page_keyword";//索引名字

$s->setMatchMode ( SPH_MATCH_PHRASE );

$s->SetSortMode ( SPH_SORT_EXTENDED, $order_column );

$s->setMaxQueryTime ( 100000 );

$s->setLimits ( 0, $limit_total, $limit_total );

$keyword_sphinx = iconv ( "gbk", "utf-8", $keyword );

$result = $s->query ( $keyword_sphinx, $indexname );

$s->close ();

if ($result ['total'] > 0) {

    var_dump($result ['matches']);

    //根据打印出的结果进行相应的读取

}

2.采用mysql二进制网络协议的代码：

//检查sphinx是否能连接，不能重试两次，能则连接,用mysql14协议

protected function checkSphinx() {

    $flag = true;

    $retries = 0;

    while ( $flag && $retries < 2 ) {

        $conn = mysql_connect ( "{$_ENV ['db_host']}:{$_ENV ['current_sphinx_port']}" );

        if (! $conn) {

            //此处为如果连接不上就更改配置文件，根据项目需要来写

            //global $configDefault;

            //updateConfig ( $configDefault );

            $retries ++;

        } else {

            $flag = false;

            break;

        }

    }

    if ($retries >= 2) {

        die ( "Please contact with administrator." );

    }

    return $conn;

}

  

$order_column = 'id DESC,time DESC';//排序规则

$conn = mysql_connect ( "sphinx_host:sphinx_port" );

//以上代码亦可使用$conn = checkSphinx ();来代替

if (! $conn) {

    return - 1;//连接不上返回状态

}

$keyword_sphinx = iconv ( "gbk", "utf-8", $keyword );

//keyword为索引名字

$sql = "select * from keyword where match('{$keyword_sphinx}') order by {$order_column} limit {$limit_total} option max_matches={$limit_total}";

$result = @mysql_query ( $sql, $conn );

  

$i = 0;

while ( ($row = mysql_fetch_array ( $result )) !== false ) {

    var_dump($row);

    //根据打印出的结果进行相应的读取

}

$totals = $this->getTotalFound ($conn);//获取总记录个数

如何获取总记录个数参考：sphinxql如何得到结果数？show meta的详细说明？

关于开启mysql二进制网络协议参考：Sphinx/MySQL 协议支持与SphinxQL
