Zend Framework教程-Zend_Helpers-动作助手-Url

Url主要用于创建url；
public function simple($action, $controller = null, $module = null, array $params = null)
public function url($urlOptions = array(), $name = null, $reset = false, $encode = true)
public function direct($action, $controller = null, $module = null, array $params = null)

<?phpclass IndexController extends Zend_Controller_Action{    public function init()    {        /* Initialize action controller here */    }    public function indexAction()    {        //$urlParser = $this->_helper->getHelper('UrlParser'); 		//var_dump($urlParser->parse('http://blog.csdn.net/mengxiangbaidu/article/details/7236249')); 		    	$url = $this->_helper->getHelper('Url');    	    	$action = 'actionname';    	$controller = 'controllername';    	$module = 'modulename';    	$params = array('param1'=>'中文参数');    	var_dump($url->simple($action, $controller, $module, $params));    	    	$urlOptions = array(    			'action'=>$action,    			'controller'=>$controller,    			'module'=>$module,    			'params'=>$params);    	var_dump($url->url($urlOptions));    	var_dump($url->direct($action, $controller, $module, $params));    	     	exit;    }}
