Zend Framework动作助手Url用法详解

本文实例讲述了Zend Framework动作助手Url用法。分享给大家供大家参考，具体如下：
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://www.jb51.net/article/80479.htm"））;$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;}}

string（101） "/helper_demo1/public/modulename/controllername/actionname/param1/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0"
string（101） "/helper_demo1/public/modulename/controllername/actionname/params/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0"
string（101） "/helper_demo1/public/modulename/controllername/actionname/param1/%E4%B8%AD%E6%96%87%E5%8F%82%E6%95%B0"
