Zend Framework 事务处理问题
官方给出一个示例，如下：

<?php<br />
<br />
// 创建一个 $db对象, 然后开始做一个事务处理.<br />
$db->beginTransaction();<br />
<br />
// 尝试数据库操作.<br />
// 假如成功,commit该操作;<br />
// 假如, roll back.<br />
try {<br />
    $db->query(...);<br />
    $db->commit();<br />
} catch (Exception $e) {<br />
    $db->rollBack();<br />
    echo $e->getMessage();<br />
}<br />
<br />
?>

我写的实例中，确没有通过，而是提示
Fatal error: Uncaught exception 'PDOException' with message 'There is already an active transaction' in E:\php\ZendFramework\library\Zend\Db\Adapter\Pdo\Abstract.php:305 Stack trace: #0 E:\php\ZendFramework\library\Zend\Db\Adapter\Pdo\Abstract.php(305): PDO->beginTransaction() #1 E:\php\ZendFramework\library\Zend\Db\Adapter\Abstract.php(484): Zend_Db_Adapter_Pdo_Abstract->_beginTransaction() #2 D:\svnrepos\WiClub\src\application\models\shop.php(76): Zend_Db_Adapter_Abstract->beginTransaction() #3 D:\svnrepos\WiClub\src\application\controllers\ShopController.php(507): shop->inserttest(Array) #4 E:\php\ZendFramework\library\Zend\Controller\Action.php(513): ShopController->shopaddtestAction() #5 E:\php\ZendFramework\library\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('shopaddtestActi...') #6 E:\php\ZendFramework\library\Zend\Controller\Front.php(946): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 D:\svnrepos\WiC in E:\php\ZendFramework\library\Zend\Db\Adapter\Pdo\Abstract.php on line 305

似乎是提示已经有一个事务在运行？刚接触ZF不久，不太熟悉，把相关源文件贴上来吧

config.ini

<br />
[general]<br />
db.adapter = PDO_MYSQL<br />
db.config.host = localhost<br />
db.config.username = root<br />
db.config.password = 123456<br />
db.config.dbname = testdb <br />
db.config.charset = utf8<br />
date_default_timezone = "PRC"<br />
