刚开始学zf,在数据库查询上出现了一些问题
   $registry = Zend_Registry::getInstance();
//$registry->set('config', $config);
$params = array ('host'     => '127.0.0.1',
                 'username' => 'root',
                 'password' => '',
                 'dbname'   => 'zf');

$db = Zend_Db::factory('PDO_MYSQL', $params);
Zend_Db_Table::setDefaultAdapter($db);
以上代码测试ok,但是一旦执行这个语句就
$result = $db->query("select * from 'album'");
会出现以上的问题  
Fatal error: Uncaught exception 'Zend_Db_Adapter_Exception' withmessage 'The PDO extension is required for this adapter but theextension is not loaded' inC:\AppServ\www\learn\lib\Zend\Db\Adapter\Pdo\Abstract.php:95Stack trace:#0 C:\AppServ\www\learn\lib\Zend\Db\Adapter\Abstract.php(380):Zend_Db_Adapter_Pdo_Abstract->_connect()#1 C:\AppServ\www\learn\lib\Zend\Db\Adapter\Pdo\Abstract.php(206):Zend_Db_Adapter_Abstract->query('select * from '...', Array)#2 C:\AppServ\www\learn\index.php(27):Zend_Db_Adapter_Pdo_Abstract->query('select * from '...')#3 {main} thrown in C:\AppServ\www\learn\lib\Zend\Db\Adapter\Pdo\Abstract.php on line 95
我的php版本是5.1.1   
zf版本1.0

Zend_Db需要pdo扩展的支持才可以运行
打开php.ini，找到以下两行，
;extension=php_pdo.dll
;extension=php_pdo_mysql.dll
将前面的分号去掉，保存后重启apache。

我的php.ini没有
;extension=php_pdo_mysql.dll

我的版本是5.2.3
只有
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_pdo.dll
extension=php_pdo_sqlite.dll
