PHP讀取sphinx實例

閱讀原文：http://yzswyl.cn/blread-1611.html

1.未采用mysql二進制網絡協議的代碼：

//檢查sphinx是否能連接，不能重試兩次，能則連接,不用mysql協議,僅供參考
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 ()) {
            //此處為如果連接不上就更改配置文件，根據項目需要來寫
            //global $configDefault;
            //updateConfig ( $configDefault );
            $retries ++;
        } else {
              $flag = false;
            break;
        }
    }
    return $s;
    if ($retries >= 2) {
        //sendemail or not
        return false;
    }
}
  
$order_column = 'id DESC,time DESC';//排序規則
//$s = checkSphinx ();
$s = new SphinxClient ();
$s->setServer ( 'sphinx_host', 'sphinx_port');
//以上兩句代碼亦可使用$s = checkSphinx ();來代替
$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']);
    //根據打印出的結果進行相應的讀取
}

2.采用mysql二進制網絡協議的代碼：

//檢查sphinx是否能連接，不能重試兩次，能則連接,用mysql14協議
protected function checkSphinx() {
    $flag = true;
    $retries = 0;
    while ( $flag && $retries < 2 ) {
        $conn = mysql_connect ( "{$_ENV ['db_host']}:{$_ENV ['current_sphinx_port']}" );
        if (! $conn) {
            //此處為如果連接不上就更改配置文件，根據項目需要來寫
            //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';//排序規則
$conn = mysql_connect ( "sphinx_host:sphinx_port" );
//以上代碼亦可使用$conn = checkSphinx ();來代替
if (! $conn) {
    return - 1;//連接不上返回狀態
}
$keyword_sphinx = iconv ( "gbk", "utf-8", $keyword );
//keyword為索引名字
$sql = "select * from keyword where match('{$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);
    //根據打印出的結果進行相應的讀取
}
$totals = $this->getTotalFound ($conn);//獲取總記錄個數

如何獲取總記錄個數參考：sphinxql如何得到結果數？show meta的詳細說明？
