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 .

这里针对linux和windows提供两种连接方式。
2.mssql.php 中的为 protected $_pdoType = 'sqlsrv';

3.ZF 的web.xml 数据库配置文件改成：

期间遇到中文乱码问题

针对不同的类型，进行不同的处理。
希望本文所述对大家基于Zend Framework框架的PHP程序设计有所帮助。
