在使用zend framework时遇到’The mysql driver is not currently installed’错误！！

Fatal error: Uncaught exception ‘Zend_Db_Adapter_Exception’ with message ‘The mysql driver is not currently installed’ in D:\svn\news-qzx-com\Zend\Db\Adapter\Pdo\Abstract.php:112 Stack trace: #0 D:\svn\news-qzx-com\Zend\Db\Adapter\Pdo\Mysql.php(96): Zend_Db_Adapter_Pdo_Abstract->_connect() #1 D:\svn\news-qzx-com\Zend\Db\Adapter\Abstract.php(459): Zend_Db_Adapter_Pdo_Mysql->_connect() #2 D:\svn\news-qzx-com\Zend\Db\Adapter\Pdo\Abstract.php(238): Zend_Db_Adapter_Abstract->query(‘SET NAMES utf8′, Array) #3 D:\svn\news-qzx-com\common.php(77): Zend_Db_Adapter_Pdo_Abstract->query(‘SET NAMES utf8′) #4 D:\svn\news-qzx-com\index.php(12): require(‘D:\svn\news-qzx…’) #5 {main} thrown in D:\svn\news-qzx-com\Zend\Db\Adapter\Pdo\Abstract.php on line 112

解决方:打开php.ini打到 extension=php_pdo_mysql.dll 去掉前面的分号就行了。
