zendframework中文字段进行筛选,取不出mysql中文字段,英文和数字字段都可以
以下是IndexController.php控制器部份,这部份用中文字段进行筛选，无法取出记录

<br /><?php<br />require_once 'Zend/Controller/Action.php';<br />require_once 'application/models/goods.php';<br />require_once 'application/models/db.php';<br />require_once 'BaseController.php';<br /><br /><br />	class IndexController extends BaseController<br />	{<br />		<br />		function indexAction()<br />		{<br />			$this->view->title='aaaa';					<br />			$goods=new goods();		<br />			$dbs=$goods->getAdapter();//适配器查询返回的数据是数组		<br />			$cname="索尼高性价比入门单反  A580 单反相机【演示数据】";<br />			$res=$dbs->query("select * from shopnc_goods where goods_name=".$dbs->quote($cname)." limit 0,9")->fetchAll();	<br />			echo "<pre class="brush:php;toolbar:false">";<br />			print_r($res);<br />			echo "

";
exit();

}

}
