zend框架实现支持sql server的操作方法

本文实例讲述了zend框架实现支持sql server的操作方法。分享给大家供大家参考,具体如下:

1.修改Zend/Db/Adapter/Pdo/Abstract.php中的connect方法

protected function _connect(){  // if we already have a PDO object, no need to re-connect.  if ($this->_connection) {    return;  }  // get the dsn first, because some adapters alter the $_pdoType  $dsn = $this->_dsn();  // check for PDO extension  if (!extension_loaded("pdo")) {    /**     * [url=home.php?mod=space&uid=86763]@see[/url] Zend_Db_Adapter_Exception     */    require_once "Zend/Db/Adapter/Exception.php";    throw new Zend_Db_Adapter_Exception("The PDO extension is required for this adapter but the extension is not loaded");  }  // check the PDO driver is available  if (!in_array($this->_pdoType, PDO::getAvailableDrivers())) {    /**     * @see Zend_Db_Adapter_Exception     */    require_once "Zend/Db/Adapter/Exception.php";    throw new Zend_Db_Adapter_Exception("The " . $this->_pdoType . " driver is not currently installed");  }  // create PDO connection  $q = $this->_profiler->queryStart("connect", Zend_Db_Profiler::CONNECT);  // add the persistence flag if we find it in our config array  if (isset($this->_config["persistent"]) && ($this->_config["persistent"] == true)) {    $this->_config["driver_options"][PDO::ATTR_PERSISTENT] = true;  }  try {    //print_r($this->_config);exit;    if($this->_config["pdoType"]=="sqlsrv"){      $this->_connection = new PDO( "sqlsrv:Server=".$this->_config["host"].";Database = ".$this->_config["dbname"], $this->_config["username"], $this->_config["password"]);      $this->_connection->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );      $this->_connection->setAttribute( PDO::SQLSRV_ATTR_ENCODING, PDO::SQLSRV_ENCODING_UTF8 );      $this->_profiler->queryEnd($q);    }elseif ($this->_config["pdoType"]=="dblib") {      $this->_connection = new PDO(        $dsn,        $this->_config["username"],        $this->_config["password"],        $this->_config["driver_options"]      );      $this->_profiler->queryEnd($q);    }    // set the PDO connection to perform case-folding on array keys, or not    $this->_connection->setAttribute(PDO::ATTR_CASE, $this->_caseFolding);    // always use exceptions.    $this->_connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  } catch (PDOException $e) {    /**     * @see Zend_Db_Adapter_Exception     */    require_once "Zend/Db/Adapter/Exception.php";    throw new Zend_Db_Adapter_Exception($e->getMessage());  }}

这里针对linux和windows提供两种连接方式。

2.mssql.php 中的为 protected $_pdoType = "sqlsrv";

protected function _dsn(){    // baseline of DSN parts    $dsn = $this->_config;    // don"t pass the username and password in the DSN    unset($dsn["username"]);    unset($dsn["password"]);    unset($dsn["driver_options"]);    if (isset($dsn["port"])) {      $seperator = ":";      if (strtoupper(substr(PHP_OS, 0, 3)) === "WIN") {        $seperator = ",";      }      $dsn["host"] .= $seperator . $dsn["port"];      unset($dsn["port"]);    }    // this driver supports multiple DSN prefixes    // @see http://www.php.net/manual/en/ref.pdo-dblib.connection.php    //print_r($dsn);exit;    if (isset($dsn["pdoType"])) {      switch (strtolower($dsn["pdoType"])) {        case "freetds":        case "sybase":          $this->_pdoType = "sybase";          break;        case "mssql":          $this->_pdoType = "mssql";          break;        case "sqlsrv":          $this->_pdoType = "sqlsrv";          break;        case "dblib":        default:          $this->_pdoType = "dblib";          break;      }      unset($dsn["pdoType"]);    }    // use all remaining parts in the DSN    foreach ($dsn as $key => $val) {      $dsn[$key] = "$key=$val";    }    $dsn = $this->_pdoType . ":" . implode(";", $dsn);   // print_r($dsn);exit;    return $dsn;}

3.ZF 的web.xml 数据库配置文件改成:

<db>  <adapter>PDO_MSSQL</adapter><config>    <host>localhost</host>    <username>sa</username>    <password>123456</password>    <dbname>testdb </dbname>    <pdoType>sqlsrv</pdoType>  </config></db>

期间遇到中文乱码问题

function convert2utf8($string){    $config = $this->getCfg();    $pdoType = $config->db->config->pdoType;    if($pdoType == "dblib"){      return iconv("gbk","utf-8",$string);    }elseif($pdoType == "sqlsrv"){      return mb_convert_encoding($string,"UTF-8","auto");    }}function convert2gbk($string){    $config = $this->getCfg();    $pdoType = $config->db->config->pdoType;    if($pdoType == "dblib"){      return iconv("utf-8","gbk",$string);    }elseif($pdoType == "sqlsrv"){      return mb_convert_encoding($string,"GBK","auto");    }}protected function &getCfg() {    if ($this->cfg_ === null) {      $registry = Zend_Registry::getInstance();      $this->cfg_ = $registry->get("web_config");    }    return $this->cfg_;} 

针对不同的类型,进行不同的处理。
